I believe they are 1" lines. They are blue. I'll measure them tomorrow. They could be 1/2 I guess. My return is on the factory line from about a foot below the "T" at back of the motor above the starter until it reaches the top of the tank then it goes back to the blue bigger hose. I've always only dropped 3 psi before but now I am dropping 6 at WOT. I can make it drop 3 psi in neutral revving it to 2500. I'm a little worried that it may be damaged. It also pops with a miss if I WOT it while in neutral. Right after I hit the throttle it'll pop then revv up fine with a puff of smoke.

Ok guys, I got it fixed. You'll never believe this crap. While I had the drivelines out, I think I forgot to mention that I dropped the fuel tank and repaired the fuel gauge sender. When I got it all back together and started it, my fuel gauge was pegged at 30 psi at idle. I adjusted my air dog back down to 18 at idle and until today I never could figure out what happened. Apparently when I put the fuel tank back in the dark, I pinched the return line between the tank and frame.. I found it today and fixed it and when I started the truck, my fuel psi was 10. I adjusted it back up and it's running great. My final question is, how much damage do you think I did running it like that for nearly 100 miles trying to figure the stuff out? It seems to smoke a little more than it ever has now but I've also always had fuel leaks that I no longer have. It's black smoke. Not white or anything. I am dropping 6-8 psi now tho at WOT. I am dropping from 18 down to 10. Should I bump it up a little more to say 20 at idle to keep 12 or so at WOT?

Ok so I got the codes cleared and the only 2 that come back now are p0251 and p0252. I'm beginning to fear the worst has happened. On a side note though, yes the ecm plug could have been sprayed directly. I know the ecm itself was but the truck had no batteries in it at the time and didn't have for about 5 days after.. idk guys, is there anything left that could cause this other than the pump? I have not cleaned the ground for the ecm but could that even cause these codes??

Ok I just had the codes ran again. Let me say 1st that I have no way to clear codes at the moment but prior to me pressure washing the entire engine bay, changing the clutch, and changing the fender, I had no check engine light or codes other than the 1698 for a bad ground on passenger side battery. The truck ran flawless and I've never had a problem with it. The glow plugs I unhooked and left off the truck when I changed the fender. I'll post a pic of the codes now and tell me where to go next please. P0237 P0234 P0113 P1698 P0251 P1287 P0380 P0382 P0236 P0252 https://photos.app.goo.gl/DhcQ9c4xJYznQJ82A

Ok, I blew out all the electrical plugs with air to make sure they were dry. I also replaced the main ground wire on the drivers side battery. I still have the same problem. 1600 or so it starts popping like a rev limiter up to 2100 and blows some black smoke. I can hear the turbo spooling up but where should I go next?

A week or so before the clutch the ground on passenger side battery pulled out of the gray connector and caused the "NO BUS" to come on where the odometer reads. I assumed this code was from that. I never checked or cleared the codes then.

I dont have the factory fuel pump anymore. I have the air dog 2 lift pump. I will try blowing out all of these pins today. I'll post back with results. Thanks

I need help here. I have a 2001 with the 6 speed. The clutch went out a couple weeks ago so I decided to do some long overdue work on the truck while tackling the clutch job. I put a new south bend dd in and a new slave cylinder assembly. I also changed the drivers fender as well and pressure washed the entire engine and undercarriage. The truck ran perfect when I shut it off to do all the work. I have the air dog 2 with a 2 year old industrial injection vp44. I've always had 20 psi fuel pressure at idle with about 17 at WOT. When I got everything back together and started the truck, it idles perfect but it won't rev above 2000 rpm and started defueling causing a missing and backfire around 1600-1800. It pours black/blue smoke like it's tuned but it has no programmer. I also had a horrible sudden fuel leak from the connector tubes so I changed all the orings and fixed that problem but still there was no change to the engine sputter and defueling. I ran the codes and had these codes P0234 p0113 p1698 p0251 p1287 p0252. I can't help but think I'm missing a ground somewhere or have something wrong or wet but can't figure it out. I have a hard time believing that the IP just quit at the same time I did all of this work. Any help would be appreciated.
