Lift pump has a lifetime warranty. Hopefully I get it narrowed down tomorrow. I have not even looked for the tee in the back of the head yet as I have not seen any evidence of fuel leaking from there. What’s the best way to access that tee?

Ok, the return line wouldn’t cause the low pressure while running would it Everything is JIC and I beiieve everything downstream of VP44 is stock

Good afternoon, I put a titanium fass lift pump along with a Fleece sureflo sending unit on my 2001 pickup about a year and a half ago. It’s been flawless for a few thousand miles. I had been noticing some slow starts when warm. Not bad just a few more revolutions than what was normal. I put some NAPA cross referenced fuel filters on because I didn’t have FASS replacements and didn’t have the time to wait . I started to take a trip recently and fuel pressure dropped significantly. I got the truck home and parked it for a month . I wasn’t real confident about the NAPA filters so i replaced with the direct replacement FASS filters. Test drove the truck for an hour or so and all seemed fine. Today it did the same thing again. I had gotten 17-19 psi at idle and 15-17 WOT. Today it dropped to 15 idle and drops significantly at WOT. I talked to tech support at FASS and he mentioned something about a valve in the VP 44 might be a problem. Now when I turn the key on PSI jumps to 17 and drops to zero momentarily when I start the pick up. I’m in the process of putting a mechanical gauge in line to verify that the brand new auto meter pillar gauges are not the problem. Does this sound like a VP44 problem? Truck only has a 160000 miles, but I assume VP44 and everything beyond is original equipment . Thanks, Kevin

Congratulations!

Sorry Im not closer, Id give you a hand

JIC really is the best way to go with any pressurized hydraulic or pneumatic connection

I grew up n Tx. I understand 😁

Weather is still not conducive to a lot of wind therapy where I’m at. Lots of time for maintenance on my FLHC and FLHTCUI . Looking fwd to a long ride in May

I was just making plans to reseal my OEM vacuum pump and replace PS pump. Glad I found this. Thanks for sharing fellas , I’ll share when in done

Can you please remind me how to edit my signature? TIA, Kevin

Congratulations

Good check up?

So,I have an 01 with nv4500. 4x4. When I bought this thing a year ago it needed tires real bad . I bought it in Couer d alane, ID with 3 may pops and a will pop lol. Looking to buy tires before I drove I it home to Wa coast I ignorantly looked for 35’s and rims and would have bought them if they would have had them in stock. Thankfully I ended up buying stock size L285/75R16 on to the stock rims. Did all of these pick ups come with the same rear end gear ratio? How can I figure my gear ratio?

Is the rear end on these trucks heavy duty enough to stand posi traction? Am I going to snap axles or anything else? Any reason I shouldn’t do this?

Yeah I got stuck in the sand the other day. I wouldn’t have if it would have been posi traction. I’ve never needed to get into a differential. Pretty straight forward install?
