fuel line modifiction
 

ok im updating my fuel lines to 1/2 this weekend and was thinking about useing pex pipe? i was wondering if that stuff would hold up to diesel fuel? the reason i ask is because im a plumber and have lots of fittings and pipe laying around. or dot break line maybe?

The stainless variety?

stainless

always use stainless on those parts

no plastic pex pipe and brass fittings

why 1/2"? 3/8" is plenty

I picked up some 1/2 inch hose from NAPA that was approved for any fuel, it's good heavy duty hose. I can't remember the price but I was suprised at how cheap it was. I ran it all the way from the draw straw to the lift pump, and I know I didn't need 1/2 but figured if I wanna go with an aftermarket pump and dual feed in the future it would already be there since I had to do fuel lines anyways. :c:

thats the route ill mostlikely take is the mult fuel the reason for half is because my cummins is starving for fuel with the factory 1990 f350 fuel lines
