    Lift pump pressure adjustment

    With today's electronic lift pumps from FASS and Airdog, TYPICALLY they do not come with a way to easily adjust fuel pressure. There are options out there but they are quite spendy and there's easier ways to accomplish the same thing. So for those who have pumps that do not have an external/adjustable regulator, your pump more than likely uses a spring and ball to regulate fuel pressure. Springs should be provided from the pump manufacturer to provide adequate pressures. Typically between 16-18psi. The pumps use a hard plastic ball, either a Buna or Viton ball. This will create a seal when the pump is off and keep fuel from "leaking" or "moving" in the lines once the pump is off. The springs can be inconsistent which can cause erratic fuel pressure readings or lower then expected readings. Using this diagram of a FASS system, if you remove the hose/fitting that is connected to the "air/vapor return to the tank" you will find a spring a ball, it will look like this. If your spring comes out looking like this... You were more then likely experiencing erratic fuel pressures. You could either straighten out the spring and reinstall or replace the spring all together. I only have experience with FASS but I called FASS support and they sent me a replacement. I imagine the same would happen with Airdog. The next factor in all this are the balls. In my research I've found that FASS uses a Buna ball and Airdog uses a Viton ball. I was having a mixed bag of issues, erratic fuel pressures and also lower then expected fuel pressures. Upon removing the spring and ball I found my spring had twisted (previous pic) and that the ball had indented into the spring. You can see the indentation here. I tried a couple replacement balls from FASS with the same results. I then went with a Viton ball and the problems haven't returned. The Viton ball is stronger material and seems to be holding up well. If you're still having lower pressure issues then you can put a washer in to shim the spring and raise pressure. The following measurements should get you in the ball park but make sure you double check you're not adding any additional restriction by using to small of an ID. Here are the measurements: OD - .631" ID - .320" thickness - .039" ***This washer/shim should be added between the fitting and the spring NOT between the spring and ball.*** So what helped fixed my issues was going with a Viton ball and a 17lb spring. This isn't meant to say one company is better then the other, just what I found out in my research and what fixed my problem. The point of this article is to help educate others on potential fixes. ***Additional notes*** List of parts I used Viton Ball HERE 17lb spring HERE I understand these are labeled as Airdog parts but they worked fine in my FASS 150. The Airdog fitting DID NOT work on my FASS pump so if you're looking to replace that on your FASS 150 you would need to contact FASS to get a replacement. Here's the difference FASS LEFT AIRDOG RIGHT Pretty noticeable difference in threads and overall length so if replacing these fittings they must be brand specific.
  2. Hello, Curious if anyone has done this FASS 150 upgrade, and if so, your results/comments please. Thanks
  3. So I'm in the process of putting the truck back together and I ran into an issue. My fass draw straw is oof the old design, the new fittings I got for my fass don't work with the fass95. So I was going to take the inner during on the draw straw and use that on the fass pump. But that leaves my draw straw. I was looking at getting the Fass Sump kit since it allows you to draw from the inside of the bowl. Being here in Jersey I don't foresee any issues with hitting brush, etc that could cause it it be knocked out. I refuse to use a sump that requires an external hose, as I'm currently dealing with an enlarged hole for my old draw straw. If your wondering this is what it looks like. https://www.xtremediesel.com/fass-stk-5500-fuel-sump-kit?gclid=EAIaIQobChMIyKPM25us5wIVGKSzCh20sQvFEAQYASABEgL2a_D_BwE Anyone have any long term reports of it's reliability, if it leaks, etc. I'm currently on the fence with buying one, vs trying to find more fittings. It would be nice to get back to putting 30 gallons of diesel in the truck lol
