Fuel systems, let's see 'em

[redmedicine]

Like it says, let's see your fuel systems. I would start, but right now mine is a pile of -6 hose, ends, fittings, electric pump, return style regulator, 20 gal fuel cell and that's about it. Hence, I would love to see what you guys have. Especially hose/ line routing under hood and maybe if someone else has a "universal" fuel cell mounted. Post 'em up folks!

That is from the rear of the engine, right? Where do you have the lines entering the engine bay. I am trying to figure if I want them pass side, drivers side, in front or rear of the shock towers, etc. Also not sure where I want to mount my regulator. I bolted it up at the front drivers side of the intake just to see what my options would be, but I'm not convinced. I will be having a ton of underhood heat and am trying to keep that in mind. Thanks for the post.

On my previous 68 Stang, I ran my duel feed tree facing the firewall, the regulator and fuel filter was mounted on the pass side firewall and the lines ran down and under the car on the passenger side out to the back.

[redmedicine]

I am thinking that I am going to have to run the feed and return lines outside the engine bay as much as possible due to heat/ clearance. My headers take up pretty much the entire space between the engine and firewall. I was thinking of having them enter at the front drivers side ahead of the engine. But then I would need to find a spot to run 2 -6 lines along the frame rail around the suspension, brake lines etc. I had the regulator on the firewall, but mounted to one of the bolts for the export brace. I didn't like the position and routing the lines back there was kind of iffy with all the heat. I should get some time to work on it this week and I will get some pics. How about fuel cells. Anyone?

Here are some shots of mine: http://forums.corral.net/photopost/s...t=1805&ppuser=

It's for EFI in a '65. My fuel pump and filters are mounted on the front of the fuel cell box, just aft of the diff. I also stored two pictures the same style cell box built by a friend of mine for his '65 Mustang for a carb application. His pump and filter are mounted on the side.

[redmedicine]

That's the stuff I'm looking for, thanks. I was trying to figure out how to mount/ enclose my cell and that helps a ton. Part of the problem is the cell I got, is sumped and what I thought was the side, is the rear, so it's longer than it is wide. I can make do, but it leaves some space to fill in the trunk floor. The other problem is having a 429 in a 68 with shock towers and 2" headers. Lot's of heat, not much room to route lines. Thanks for the replies folks, keep them coming.

Also, to make sure I am doing it right, anyone know the proper way to install AN hose ends/ fittings?

Red,

Both my cells in those examples are sumped. They're elevated up off the floor of the box.

If you look at the two boxes, mine (the black one) has an area on the left where I made it flush with the trunk floor. Meaning, it's narrower than the stock tank. I did this because I run rear exit exhaust and needed the room there for it. The carb car has side exit exhaust.

Not sure what you mean by the proper way to install the hose/fittings.

I also (just) stored a picture of the carb set up, where the line enters the engine compartment. It's in the stock location with the regulator on the front of the DS shock tower.

As far as installing the hose ends, when threading the end onto the collar, should it be run down all the way, or will that compress the hose too much and make it split? The problem that triggered this whole re-vamping of my system comes from the car sitting for a couple months during the winter and this spring when I flipped the pump on to start it, I had a sprinkler system under the hood. Every one of my hose sections was spewing fuel and the only thing I can figure is something in the fuel (pump gas) that broke down the lines, underhood heat killing them, or overtightening the hose ends to the point they split the hoses. They were Summit brand steel braided hoses less than a year old. I was baffled.

[redmedicine]

I like the placement of your regulator. I might have to see if I have room there. My PS pump might limit me, but it may be much better in the long run. I also plan on (eventually) running full length exhaust and need the clearance on either side of the tank. That's why I hung on to the cell.

Okay, sorry. No help there. I used push lock style hose fittings. I'm cheap and like the industrial look.

Here's my fuel system:
- Fuel Safe fuel cell
- 3/8" rubber fuel line to 180* 3/8" hard line
- 3/8" rubber fuel line from hard line to pre-filter
- 3/8" rubber fuel line from pre-filter to in-line pump
- -6AN high pressure line from pump to throttle body, dual feed line

The fuel line runs along the inside of my subframe connectors and feeds the throttle body from the rear of the engine.

I made a bracket for the regulator that bolts on where the E choke would go. The port on bottom is for the return. It has a 90* hose end fitting.

[oldbugs]

^^^Yea... um... I'm going to need some more pics of that engine bay right away^^^^^

[brianj5600]

Old turbo.





Old vs new. MP T-70 on the left and Borg Warner S475 on the right.





Still working on it.

Man that is sweet!!! I need one of those for my '66

[66mustfb]

I have a 16 gallon Fuel Safe cell that feeds into a filter and than into the pump (both mounted to a plate between the cell and the diff). AN 8 for supply, 6 for return both run up the drive tunnel to exit on the drivers side near the brake booster. The tee seen in the photo runs to the fuel rail. On the Explorer engine (2000) the fuel rail input is above cyl #8. The rail does not have a return port so hooked it to the fuel pressure regulator. Works great for me but I'm using pretty much a stock exhaust (hipo ex manifolds).

[redmedicine]

^^^That looks pretty good, 66mustfb. I think if I want a clean installation for my retulator, I am going to need to build a custom bracket. The one that came with it is pretty goofy. I should have some time tomorrow I'll snap a shot of what I am thinking so far with the regulator.

Oh, and Brianj5600, that is a BFT. I like. I have been SERIOUSLY thinking about a pair of LFT's for the wifes car. Hell, I would consider a pair for the one I am working on, but I have enough underhood heat already, no place to put them, and besides, I have no idea what I am doing when it comes to the hairdryers.

[redmedicine]

Here are a couple shots of where I am thinking of puting the regulator. The bottom outlet is the return. as you can see, I don't have a ton of room to
route and set this thing up.




Any suggestions?
And a couple feel sorry for me stranded in the back yard pics.

99coupeGT, tell me about your fuel cell/ tank. How did you mount it? My sump is going to be about that low too. Where did you mount your pump and filter? Looks good.

[66mustfb]

About the sump in the fuel cell...it's my understanding a fuel cell is filled with foam and the gasoline is not free to slosh around, if that's true why would a sump be needed? Is the foam not able to keep the pickup submerged ?

I have a 16 gallon "Fuel Safe" brand cell and thought I was good to go in regard to keeping gas around the pickup.

[brianj5600]

From Fuel Safe website.

The Sportsman® cell is our most cost effective soft bladder fuel cell. The Sportsman® cell meets all FIA-FT3 requirements and is designed for use with all hydrocarbon fuels. The Sportsman® bladders are constructed with a proprietary pre-coated fabric that offers a great balance of performance and price.
All Sportsman® racing cells are race ready and feature the following:
• Durable, FIA-FT3 certified Sportsman® bladder.
• Powder coated 20 gauge steel container with external mounting flange
• Full safety foam baffling, minimizes fuel slosh and the potential for an explosion
• SF6X10E fill plate comes standard with a -8 pickup (plumbed to the right rear of the cell), -8 return, -8 rollover vent valve, high quality threaded aluminum fill cap and a sending unit provision.
• Aircraft grade nut ring and gasket
• Fuel pickup assembly, factory installed
• 2 year manufacturer warranty
• Recommended upgrades: surge tank, sending unit, lightweight aluminum can and more! See the parts section of our catalog for a complete listing of all available accessories.


It looks like FS is basically the circle track style pick up, right rear corner. The last bullet recommends a surge tank for sportsman cells. I rear sumped my tank mainly because it was only about $25 in materials and was not too worried about sustained hard cornering. Here it is.

[91whiteghost]

if you plan on racing at any NHRA or IHRA tracks , check the rule books. they don't allow fuel pressure regulators to be mounted to the firewall.

Also the fuel line should run outside the frame or be protected in the area where it passes the flywheel.

[66mustfb]

Thanks for the good info but the car is just for street use. I did the fuel cell (made just for the early models) trying to improve the safety aspects of a 43 year old car.

And you did a fine job too.
May have to use a setup like yours for my wife's '65 coupe....

[redmedicine]

It is my belief that the sump would be placed, for example in a drag car, at the rear so that it accumulates under acceleration at the pickup. The foam I believe is to prevent/ minimize aereation as well as help with slosh. Mine is a street car and I don't necessarily have any plans to race, but I wanted to keep that option open. The cell that I chose I did so because I wanted to have a little more clearance around the exhaust out the back, and room to mount the pump along side the cell. The tank that fit the dimentions just so happened to be sumped. It also helped to decide where I would put the pickup. Unfortunately my width ended up being my length and vice a versa. So now I really have plenty of room on the sides for a pump and exhaust clearance. But it will still work.

I am also now leaning towards puting the regulator at the front pass side of the engine. We will see. I haven't had a whole lot of time to work on the car.

[99coupeGT]

this is my factory tank with a sump and baffles added. cost me about $160 to have it done at Powered by Ford here in Orlando. works great! Also I have a holley Red pump and Summitt 40 micron filter mounted between the gas tank and passenger side rear frame rail. never had any issues with this stuff, provides plenty of fuel for my slightly thirsty 408w :-p hope this helps!

[redmedicine]

I had consdered working with my original tank, but too much trash and the though that it may be contaminated, contributing to the deterioration of my lines, got me looking at new stuff. I am using a Mallory pump and regulator with a Fram filter. I like the way HRS65's cell is enclosed and think I will do something similar, then mount the pump and filter along the side of the enclosure. Thanks for the help. I should be ordering some parts in the next few days and will get something going. First I need to just get something rigged so I can move it to the garage.
