Engine/Transmission (1998.5 - 2002) Fass Question

[Hobart]

The question: nothing in the directions address the in-tank pump's fuel level sender. Definitely want the fuel level sender active. The directions I have don't refer to an 02 with the intanker so I'm wondering if anyone has some experience - I'd like to know what to expect before I take the tank out and start. As I remember from the Glacier directions there is some splicing to do. And since its already there, I'd like to be able in case of a Fass failure to rehook up the in tank pump.

Mine came with 6AN fittings & yes, it pumps plenty

just hook up the FASS as per the instructions included with your kit. Then install the Suction tube kit to by-pass around the in-tank pump.



The Retrofit conversion uses the factor plug that normally runs the stock lift pump on the block to run the in tank pump. When you unplug it to install our harness, you will disable the in-tank pump. Sending unit should work fine.

Just installed the new HPFP but my Westech guage/sender(Genos) mounted on the fuel filter cover has very erratic readings ,12 to 15lbs at idle but dropping as low as 5lbs on light acceleration. I hooked up a Vulcan fp guage at the injection pump- it reads a steady 15lbs and drops to 14lbs on acceleration.

I assume the erratic readings could be from trapped air? I haven't test driven the truck yet but will do so tomorrow but seems to idle ok maybe a little up and down by a 50rpms at idle (the Vulcan guage also shows a 1lb change as the idle goes up and down).

Sounds like you got a bum sending unit..... that is what they do when they are defective or going south (Not to mention some personal friends that had Westech's that ran though the exact same song and dance)... . you get a snubber with that thing? If you didnt... i would HIGHLY recomend it... ... anyone that carries Auto Meter can get you one... .

What's a snubber?

Might also be a bad ground. That's what had mine going erratic for a while. I ran a ground direct to the neg. Battery terminal & it's steady at 20 now & I can only pull it down a few lbs with heavy throttle.

Very pleased with the response - smoother and lots more power (don't understand that one) fuel pressure 15lbs to 13lbs on acceleration. My main objection is the mounting of the pump in clear sight - wouldn't last a second in a mexican parking lot (I travel mexico a lot) or any other major city in the US. So that will have to be modified asap. Then the hose connections should be 90s!
