Glenn's Sleeper Tank - Whos really making power with it 700+

I am all about the sleeper tank. I hate the look of all the crap out back. But simple physics seem to say a feed at the front of the tank defies gravity and just would not support big numbers.


My goal is 850rwhp on E85. I have the pump picked out Magnaflow 4303.


Who is REALLY making the power with this tank. Not hey I bought the setup it was packed nicely, or wow Glenn is a nice guy on the phone. Real world examples.

I posted this in Turbo because that is inline with my setup but if anyone else is reading please feel free to chime in especially any other Forced Induction.

i have that tank and not only love it but made low 700s to the tire on a humid day at 15# and expect to see upper 700s when i go back and push up the boost with better air.

note that i'm able to log my fuel pressure, among other things, and saw no signs of fuel delivery issues. that's with 10AN feed, 100 micron filter, dual walbro 392s pumps, and a 10micron filter after them.

I have the exact same setup you're thinking of doing and made just over 700rw without a fuel starve issue. My friend Matt has the tank with 3 of their sleeper pumps and made 845rw with it...real world, real numbers...And his pumps are up front of the tank, 4303 is behind

this confused me, he has a 4303 behind the tank? and 3 in line pumps for a total of 4 pumps?


The 4303 scares me a BIT with the -8 in/out, but a turbo guy on turbomustangs put down 1137rwhp (e85) with it.

Sorry for the confusion..

I have 1, 4303 pump and it's mounted behind the tank. Kurgan said he has tuned big power cars 1000rw plus with this pump. I drove it on an 800 mile round trip with this pump on e85 with 0 issues as well.

My friend Matt has the 3 sleeper pumps in front of the tank...

We both have their sumped tank...

The tube goes back into the factory fuel pump area. Where there are some baffles. The feed location has nothing to do with how the Walbro pumps in his kit get fuel. They do not need to be gravity fed the fuel. They are great at "sucking" fuel up to the pumps. I read a while back the amount of fuel they can suck from a long distance. It was impressive. (Too lazy to look up the info now haha) So as long as the feed tube is submersed in fuel the system will work. And being the tube is in the factory fuel pump location you should not have any issues.

No. I have one of the old style Aeromotive rear sump tanks. You know, the ones that starve the system for fuel when below 1/4 of a tank. hahaha The lack of proper baffling causes that issue. They changed the tanks years ago to solve that issue.

But I do run 3 Walbro pumps on my set up. The pumps are well above half of the tank. But they have no problem drawing fuel even though they are above the fuel. As long as there is fuel in the sump. I just keep the car above 1/4 tank. haha I actually plan to switch to a sleeper tank and twin Bosch 044 pumps over the winter.

I know a couple people using the sleeper tank with no issues. I have seen a local guy use the same set up where he puts a feed tube in the front of tanks where it draws from the bottom, back and factory sumps for all kinds of cars. Especially EFI conversion cars like on old muscle cars. He has said he has never had someone come back with a fuel issue. Used with a pump that car draw fuel in to itself properly of course. Some making insane power.

I also know people who have 8 second cars using factory tanks, the drop in fuel tank inserts and inline pumps. Again, with the right pumps, as long as the feed is submersed in fuel the system will work.

I also know of a few sleeper tanks w/o issues. They all make in the 700-800rw range.

I run a Glenns sumped tank, wish I could help more.

Good luck man!

700-800 range on gas or e85, big difference in volume flowing out of the tank.

I run E85 and make just shy of 800rw thru an auto, so yes I was ref'ing E85 since thats what you said.

Although they run 5spds, but make that power on E85 and the sleeper tank.
