He's probably talking about the Fedex pump. As I understand it EVERYONE
now incorporates the more reliable electronics of the original / replacement
Fedex units. There's also a bushing that went from bronze to steel IIRC. I
haven't followed the VP44 saga too closely because mine seems to be working
fine so far.
so its agreed that the lift pump is the first step, what is the word on the
in the tank pump any better??
i have in and out gauges on the filter and i kept min of 5 lbs but is goes
up and down with cold starts up and drops with petal to the metal
Relocate the stock Carter to the frame rail. install PSI guage. do away with
banjo bolts and restrictive stock steel lines. My '98.5 is done like that
after the last VP44 failure just after I got the truck. Now I've got 14psi
at idle and cannot draw it under 10psi at WOT. I used Metric/ -8 JIC
fittings to replace the banjo bolts and 1/2" Goodyear gatorgrip diesel fuel
line., from the tank to the pump.
