Fuel Pump hangers ?

Let me start by saying my knowledge on the fueling end of things lacks greatly.

Doing a simple 255 drop in on a friends car. I have the pump and all the bits that go with the install...

...aaand then I saw the ProM Fuel Pump Hanger video.

Is the hanger a necessity? Are there easy tricks to make the stock one work well? Or am I simply worried for no reason?

I enjoy DIY projects instead of giving my money away. I modified my stock hanger.
-Remove orange rubber spray cap and clamp
- Use a steel brake line one size bigger than the return line so it will fit over the existing return line.
- Bend line so it hugs along the length of the pump with 90 at the end.,
- test fit into tank multiple times before attaching
- weld or solder new longer return tube and install

The welds are not pretty but holds 40 psi without leakage.

Did this mod a week ago and now no more fuel smell from the charcoal can. Also fuel pressure rock steady with no bounce.
I also get a bit better MPG and seems like more power.

Thank you for the pics theYman and thank you guys for the tips. Car is definitely under 500hp. 275 is probably more accurate but the owner keeps hinting at a power adder so my goal is simply not having to revisit this if he decides to order one up.

Why not just clamp a longer rubber fuel hose curved away from pickup onto the return?

the pro m video is absolutely correct. You would be better off with a 155lph for your horsepower. would be quieter as well.

Most tuning issues are fuel related. Tuners "tune" around that. That's why tuner shops ask you to come in with 3/4 tank of fuel. To avoid the cavitation that occurs when you put a pump too big in.

The proof is right there in the video. Just because it fits doesn't mean that its right. '

Been there done that. Get a smaller pump and you will be fine.
