Engine/Transmission (1998.5 - 2002) Fass question

[Hobart]

Can I just disconnect the power from in tank pump and install the Fass or do I need to remove the pump. Dealer said I can add the fass without first removing the pump and that the Fass will draw through the intank pump no problem - I'm not so sure.

I had the same questions when I was installing my FASS.



I did not alter the stock fuel delivery system, much. I cut the ground wire to the in-tank pump and soldered in a fuse holder that I can access easily without dropping the tank. If I ever need the in-tank pump again, I drop in a 20 Amp fuse and off we go. I then removed the fuel feed line from the back of the stock fuel filter. I plugged the banjo with a bolt and a couple of new crush washers to keep debris out.



I installed the separate pickup line to feed the FASS. All the replies I got on this forum indicated the stock feed line would not provide adequate flow. I did all the other plumbing per FASS instructions except for where I deliver fuel to. I have the feed line from the FASS entering the back of my stock fuel filter. Now I realize some people are going to wonder why I'm putting fuel thats been filtered to 3 microns through another filter that only goes down to 7 microns. Ease of installation mainly, but the installation from under the hood looks stock as the changes I've made are in behind the stock filter.



Overall I really like my FASS. In my Mega Cab with the doors closed you can hear a faint hum with the ignition on but when the engine is running any noise from the FASS in drowned out by the engine.

Apparently this dealer has not installed any in this fassion. Because i will tell you that it will not work! :-laf Many have tried and failed.



You will need to go back to the stock sending unit or install a STK-1001 to by-pass around the in-tank pump.

would a draw straw work?

Robin "Axion" how long have you ran your fass through the stock filter pickup?Any problems to this point? Sounds to me like it would work because you always have stored fuel in the 2 filters proveded by fass giving you the volume needed to maintaine engine performance.
