Engine/Transmission (1994 - 1998) Replacing semi-rigid fuel supply/return fuel lines on 98

[DBazley]

OK the new fuel line is on, fittings are tight and no leaks anywhere. I bet the old ones were leaking quite a bit of fuel, as I notice a distinct absence of diesel fuel smell. At $ 3 per gal, kinda hard to afford that.....



Once I figure exactly where the fuel & return lines enter / exit behind the injection pump, I may just replumb back to the

tank or at least to the juncture where the steel lines leave the frame rail on the driver's side.



Thanks for the discussion, David B.

I replumbed my fuel lines with aeroquip 3/8 line. For the return I rerouted the return line over the front of the lift pump inline with the gear case, and flared it to -6AN. It is a metric line and a little smaller than 3/8" but worked. For the tank end, I got some alumnium bungs made up for it that was in 1/4 pipe threads and ran it in there.
