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?

What are my options for upgrading rear end to posi? 2001 4wd 2500

What are the benefits of 35 spline shafts, high pinion housing and 3.73 ratio?

I just scrolled this whole thread. Amazing work. Thank you for sharing your time!

5 u joints, three shafts, unserviceable wheel bearings, differential and transfer case spinning all the time needlessly was my main concern. Increasing efficiency was secondary. That being said, I like the idea of a hotter thermostat. I run diesel engines for a living and have alway understood that they are more efficient when ran a little hotter. A little bit at a time. I have a few more upgrades planned then I’ll be looking to bump up horsepower. Turbo, injectors, tuner 😁

Can you tell me more about the permanent set up to eliminate the CAD please?

Beast came with the solid axle?

I’m pretty sure that’s what it is . Haven’t had time to look at it yet everywhere I look is a project and pickup has slid back down priority list. 😂. I haven’t done any thing with vacuum lines on axle in fact I don’t even really understand what the do as the 4wheel drive manually engages…. Posi lock? I know not Thanks

Finally got the Spyntec free spin hub kit and Autometer pillar gauges installed. I’ve always hated the idea of all that hardware turning up there all the time. I rarely need 4 wheel drive . A lot of work, glad to finally check these off the list , I’ve had the parts for longer than I care to admit. It seems I’ve dislodged something in the process though. Cruise control quit working. The light comes on ,but no function

Good afternoon. I’m in the process of hooking up Autometer gauges on pillar pod. I’d like the lighting to illuminate and dim with the factory gauges. What is the best way to accomplish that?

Thank you. I will do that. Too busy this weekend and headed back to work for probably 5 weeks Monday , so it’ll be September before I can get this done, also gauges, exhaust,one piece drive shaft and free spin hubs next. I’ll post with results. Kevin

Yes.
