whats the best way to plumb the fuel system? Ive been thinking about running aluminum lines with an fittings, but lately have been looking at braided hose, going to need to plumb two systems, one for the nitrous, and the other for the engine. The thing thats got me about the braided hose is the fact that i wont have to bend any line.

Also right now i have the fuel cell in the bed and the pumps mounted on the frame rail below, how does everyone fuel Very Happy about mounting the pumps in the bed next to the cell? I like the way i have it now but the hose is pretty close to the exhaust and the pumps can be tricky to get to, if they were in the bed it would be really convient but they wouldnt be below the tank.

Im going to be picking up all the an fittings and want to do the job right, just dont know if i should use rigid line or not? Oh and im going with 1/2 inch if that matters.


Thanks

on what ? where to buy braided hose or how to set it all up ? to do it all in braided hose with fittings and everything, you will be in the neighborhood of $300-$500. maybe more depending on how you design your system.

People have tried to tell me before I shouldnt have plumbed the Galaxie with all braided- I supposedly needed to do hard line except where I needed flex (frame to engine etc) and they half-quoted an NHRA rulebook about it... Not that I am sure the rulebook would ever matter to your project.

I dont know how you plan to mount yours but rubber insulated strap clamps with #14 drillpoints can work easily and nicely imho

Pump height vs. tank I have no insight on sorry.

It is always best to have the pumps submerged. Most are great pushers but hate having to suck.

AND! lol. hard line is the best. May take longer to install but will never leak. Unless you hit something.

The main reason to run hardline is plain and simple cost. I would guess hard line would be about 1/4 of the cost of braided. Some pumps suck, some don't. My experience with the Holley pumps is they will suck pretty good and you won't have any problems with the pump mounted like you are describing. We have used a BG pump that had to be below the bottom of the tank to do anything. It would pump like crazy, but it wouldn't prime itself for squat. Fuel injection pumps can be a little tempermental also but you should be fine doing what you are describing. Now get a tubing bender and learn. Clay

Cost of running braided line adds up quick. My vote is run solid lines and only use flexible only where you need it.

I think I have posted what I ran for fuel system stuff.

1/2" aluminum hard line for sure to feed the motor. I will have to look when I get back from a business trip to see the rest.

Well, I dont smell anything with mine...

I suppose I will hard line it when this stuff gets old... I am not sure what the average life span is of braided stainless line?
