I ran 1/2" line all the way to the front I just have a small section off the tank that is 3/8". I wouldn't think that would hurt the pickup is 5/16". Do you have the name of the manager you talked to at fass,there are some real bozes there. They think I may be bleeding down and sucking air from the factory pipe dope they use on the suction side,so I am going to pull it out and redo it. I guess its possible but i dont have any leaks.He also said put new filters on,just want I want to do is but 2 filters on a system that is a week old.

You are right on that! My fitting wouldn't go on so I called them and they said I needed to file some off my factory tube so I did. Then it popped on and dripped fuel. So I hose clamped a 6" piece of 3/8" diesel hose then used a 3/8" to 1/2" straight barb and went back to their line.

Fass told me to by pass the ecm due to the fuel pump circuit possibly having issues. I wired it exactly how they told me. On the suction side I have the 1/2" line that came with the pump attached to the factory pickup on top of the tank. I fuse I used is a keyed hot. I agree with you that there is a loss on the suction side but any guesses where it could be? I have no leaks that I can see.

I'm not getting any pressure until it starts, once I start it I get pressure and normal starts every time till it sits over night. The reason I bi passed the ecm is the carter glitched a couple times on me so I wanted to bi pass the ecm. Fass recommended I do so. I still am using the relay just the 10 amp ignition for a trigger wire. When it sits over night the pump is whisper quiet and not returning any fuel to the filler neck. Once I start it sounds gargley like it has air in it, I drove it on a 2 hour run with my camper and it still sounded like that when I got there.

I just installed a Fass 165gph system on my truck. I previously was running the carter pump on the frame with no issues. Now if I let my truck sit over night it cranks longer before it starts. Also I see no fuel pressure on my gauge until after the engine starts. My fuel pump is wired to the 10 amp fuse in the cab marked ignition. After the truck sits over night I turn on the key and check the fuel neck to see if the pump is pumping and maybe my gauge is wrong but its not until the truck starts. I am lost on this one its not that complicated of a system but this has me stumped.

Sounds good to me I will order a Fass set up. What kind of new injectors do you recommend? I run Howes 16oz at every fill up.

Do you think I really need a Fass with the pressure I have now. I have been running this set up forever. I always get mixed answers on how much pressure is needed to the vp44.

What are you guys doing about your stock fuel filter set up with fass pumps. I have been running a stock pump on the frame with no banjo bolts for 15+ years with 12 to 13psi idle and no less than 9 at wot,,usually 10 to 11. But I was thinking about going to a fass system if I could get rid of the stock filter set up but I think the return line runs through it. Any thoughts?

I'm not sure what to do. I don't mind welding the flanges into my exhaust, pac brake does not make a vaccum remote one but BD does. I want to stay with a vaccum operated one. It just sucks its another 1200 bucks. That's pretty close to what my turbo is now I think.

Ok will do, and I will take the injectors out and have them tested I looked at the manifold and I didn't see any soot. I just wonder if the intercooler is leaking somewhere that I cant get to I thought about getting some bigger injectors when I up graded the turbo but I don't want to make more problems for myself.

My injection pump only has about 40,000 miles on it, I hope it isn't wore out but anything is possible. It was a reman from diesel injection service in St.louis. I need to check the back of the turbo like diesel future said. As far as my exhaust brake it seems to be working fine but I am considering taking it off and getting a BD Exhaust flange mounted one anyway. The reason I say that is because the turbo mounted one is handcuffing me on upgrading my turbo. Unless somebody has a better idea with the turbo upgrade, I would love not to buy a new exhaust break but I cant live without it.

Its close but its not all back. I took the elbow off the back of the turbo and the exhaust brake is open, unless it is messing up when im driving. My fuel mileage is down to 11mpg with my camper and it used to be at least 15.

I will check that, I have not checked that spot. I have a mechanical boots gauge(auto meter). I am using snoop, same as soapy water but bubbles at less pressure.

My elbow is not adjustable. I just got back from camping, pulling the hills in Mo at 70 my egts were around 1000 to 1100, the back roads at 55 they were 1200 and on the longs hills they hit 1200 at 70. Still to high and my mileage is crap at 11mpg. I had a little more boost with my new elbow at about 29psi wot, at 70 they were about 26 psi. I have checked and checked for boost leaks and haven't found any. I can't get to the whole intercooler to check it, I guess I could pull it and check it on the bench. The truck runs fine so I wouldn't think it is injectors. I just don't want to start up grading things without finding the problem first.

Makes sense. I am going camping this weekend so I will know then.
