Engine/Transmission (1994 - 1998) Fuel Line 90* bend prefilter to pump

[barngal6]

Replaced fuel lines front end of truck 98 12v



ended up with a sharp bend (bent) hose between prefilter and banjo bolt on pump



I was using 3/8" marine hose for supply line,

prefilter barb and banjo barb on pump turned out it was 1/2"!

I kept whining about how hard it was to get my 3/8" hose on... lol



Well, I bought a 3/8" hose barb installed it on the prefilter,

but since I had already wrestled the 3/8" hose onto the 1/2' banjo bolt,

I didn't want to take it off (and didn't have a 3/8" barbed banjo bolt to replace it)

The bend between the 2 barbs is incredibly tight,

and my hose is bent pretty sharply



I tried rigging it with a big loop, but the sharp bend was still there so configured it like the original, only hose looks bent, not smooth angle



I plan to rig a guage to check my fuel pressure, but is this common with this fix (the sharp bend)? Is it usually ok?

Just pick up the correct formed hose

Dodge has a special piece of hose for this application. For some reason, the new LP's don't seem to line up like the old ones and even that hose does not work right. If you have a sharp bend, it will split on you sooner or later.

Instead of doing a 90 degree bend, I do a 270 degree bend using 1/2"ID marine fuel line and it seems to work quite well for me.

You need a bigger loop. The problem with factory replacement is it's of lower quality than Marine Grade Diesel line. On my 96', I made the loop just barely small enough to avoid rubbing on the steering shaft. Might have loosely zip tied it to avoid rubbing?

OK, thanks. I'll replace the 3/8" barb back to the 1/2" barb and try a bigger loop.

If I could get an 90* 1'2" barb, seems like that would work better. Using marine hose

Since its hooked up for now, think I'll just run a fuel pressure test,

and if its good to go, it'll give me time to hunt down such a thing as a 90* barb fitting.

Thanks for the good info, I won't plan for it to last a lifetime.
