It is cool, but not too practical, unless you can tow a trailer on skis behind it for you cargo. Basically a tractor with no field to plow.

What is his RPM at 63 MPH? Too much torque for his torque converter? Did he try it with OD off?

Just hit 47 on Dec. 19th 2009, I am in the middle of the road with the rest of you.

OK, guys Chip sells the Fass, but do you know of a better cheaper place to buy the pump? And I am pretty sure my FL already has the 1/2" lines from the factory, since I was just out there, I did the volume test and got just shy of 1 - 1/2 quarts with the key on no start. I put in a new fuel filter, and even swapped out the transfer pump. With fuel temperature in the teens, I am still only getting about 8 PSI with a brand new OEM transfer pump. I still have a suspicion that the VP44 is already failed due to a defective computer? I agree it makes good sense that excess fuel that is by passing the ball check banjo is a good idea for IP cooling and lubrication is a good idea.

You are the first one to consider that pressure to be too low. My ears are open and I am listening to you. Will that low pressure cause the problems I describe, or will it just be harmful to my VP44?Blue Chip did not have any problem with that pressure, and the diesel truck repair shop that scanned for codes said it was OK? I am planning on doing the fuel volume test, and air bubbles on the pump, and throwing in a new filter for good measure. I do keep a spare OEM pump in my truck for emergencies, but I would really like to go with a Fass.

Great site, glad I found it. My name is Bob Donnelly, I have a Freightliner FL50 with a Cummins ISB and, Fuller Eaton 6 speed. At 117K I replaced my VP44 because the truck was not running the same. Chip at Blue chip diesel, determined the computer on the VP44 was bad, so I replaced it , and the power was back. At only 120K I am having the same issues. Chip said to take it in for DTC scan. I did, it has no codes, the owner of the shop, said to test the wastegate, and to replace the leaking exhaust manifold gaskets. The wastegate leaked, so it has been replaced, and the manifold has new gaskets and bolts. I installed a fuel pressure gauge in dash at the time of the VP44 replacement, because pumps have failed before, and I usually would not even know this until a filter change or a flat spot on acceleration. I am getting about 10 PSI at idle and 7-8 psi at WOT. Both of these pressures will drop when it is colder out and slowly rise as the fuel thins out. If any one has any ideas, other then I got a bum VP44 let me know.Once again, great site, and thank you Mopar1973Man for all of your effort.
