Hello, I recently bought an '01 cummins and come to find out the previous owner had recently taken off a FASS system and left the stock fuel filter out of the plumbing when he stuck a regular lift pump back on...so since the truck had no fuel filter the vp died and I ended up putting a new one on. I feel like an idiot but live and learn I guess

Anyway, I had a guy put on a brand new vp and he plumbed in an inline fuel filter right before the frame rail mounted holley blue thats on the truck now. Is this enough for this truck? I see those FASS systems with those giant filters and all I got is this little bitty one. How am I supposed to drain water out of the fuel like stock? I can't can I? Also, I have a vulcan mechanical fuel pressure gauge and my pressure has slowly gone down over the past month and a half that I've had the truck back w/ the new vp. It was about 14 idle 10 wot and now its about 11 or so idle and I can pull it down to about 7-8 wot. Is the little filter already clogged? Or is the holley dying? Forgive me if this is ignorant...I'm new to the diesel world! Haha. I'd buy the dang $664 full FASS system with filters and be done with it and not worry about the pressure anymore but I don't have that kind of money to spend right now. I just want my new vp to last as long as humanly (...electronically?) possible!

 

Do you know what micron the filter is filtering? Believe 10micron is stock. I have a permacool filter/water seperater that filters at 2 micron before the holley. Spin on filter.

 

I have the stock fuel filter/water separator in place, plus I added the GDP MK-2 (2 micron) filter kit, between the stock filter and the IP. I also added the GDP Fuel Boss fuel system. My psi run between 8 psi at idle, and hits 30 psi at 2,200 rpm. Unlike the electric pumps, the Fuel Boss is mechanical pump, psi goes up at a linear rate with increased throttle.
I would highly recommend a 2 filter system (7 micron + 2 micron) and a aftermarket fuel system. Nobody likes getting stranded out in the middle of nowhere with a bad LP, which ends up ruining your IP as well.

 

Do they offer the GDP Fuel Boss System for the 2nd gen's?

 

I'd bet the guy sold the truck because he knew the IP was dying.

 

yes they do

I've got an airtex pump as a replacement from O'Rielly's moved it to the framerail with a big line/relocation kit from Vulcan and am very happy with the 17-18 psi at idle, 11-12 psi WOT, but I'm still really thinking about this setup. I really like that you would have your electric pump already installed as a backup, and for priming the system

Anybody got one of these on a second gen? What pressures are you seeing?

 

I don't honestly know. I had a very reputable diesel mechanic do the job so I'd like to think my simple setup is enough but I'm not sure. All I have is the little clear plastic jobby with a filter inside it thats plumbed in right before the lift pump. Where did you buy the permacool filter kit? I did a quick search and saw that they were something like $39.99? Thats not bad at all. Do you have the part # you used?

 

Hey I found these three perma cool items on summit. Which one would best fit my application? The first one looks like its for dual carbs. The other two the only thing I can see is the thread size is different but is that it? Why such a price difference? Thanks!
