this is for my tpi conversion. i know the closer to the tank the better. and fortuneatly i already have the return line stock installed. but i was wondering if its ok to put it in the cab or put it on the frame rail?

IMO, you need to mount it on the frame rail near the tank. Electric pumps push better than pull. I would also find a way to insulate it ( rubber mount it) to keep the noise down

in the cab,, if you want to be covered in fuel if a line lets go..
mount it on the frame

You'll want it down low so it also gets the syphoning to help. Frame rail under the cab is the best location.

alright. well what i think that i am going to do is remove the feed line and mod it with screw in fittings and flare it so i don't have to run many chunks of rubber hose to connect the pump. at least i don't have to worry about installing the return line since mine has the factory return line

You might double check the diameter of that return line to be sure it's sufficient for TPI. A problem I ran into was the factory return in a stock '72 sender was way too small and would end up shooting your fuel pressure waaaaay up. Let us know what you come up with!

Hi stevencvn72

Putting any fuel component in the passenger compartment is a CAPITAL NO-NO!!!!!

Even proper fuel pressure gauges isolate any fuel from the passenger compartment.

Mounted mine right across from the tranny in the frame rail right where the tranny cross member is located that way it was kinda protected and slightly hidden.

Is the fuel tank considered a fuel component?

On my 72 with a TPI 350 I mounted the fuel pump on the frame rail and used the stock sending unit as for the supply and return lines with no problems. Just avoid running it below 1/4 tank.

Heh-heh, holy brainfade, you got me there. Been so long since that butt-bomb was in my truck I forgot about that. Guess I need to get out more.
Way back when my (then) future ex-wife proclaimed that neither she nor her son would get into that truck until the cab was "dry". Hmm, I guess maybe something positive did come out of that disaster, after all.
The factory putting fuel in the cab was bad enough, but the thought of DIYers plumbing gasoline through the cab kinda gives me the willies. A really bad place to have one of those "Bubba" moments.
I think my statement still applies, especially to modifications.

Nice catch, Longhorn!
