Cumminsman, The commin rail engines are not as crititial as the VP44 trucks, but I have heard of some of these transfer pumps failing. The low pressure light or fuel gauge are excellent to have for all of these trucks. The inline pump is still a good idea, the extra fuel that is not used isjust returned to the tank. I do recommend that you run the inline pump off of a relay controlled by the factory fuel pump wiring.

 

I have a 99 and recently replaced my stock fuel pump with one from Oreilly's put back in the stock location instead of the dealer fix in the tank. Can I still run the holley fuel pump as well to get more pressure??

Check out Espar Heaters at Cummins or on the web. It's the only sure fire way to beat the winter diesel truck blues. Also I'd recommend checking the front end out at your local mechanic. Mines an 05 and has only 125,000 Kilometers on it-about 80,000 miles and the front end is toast one u joint rusted out and one sealed front bearing, stabilizer and upper and lowers are showing serious wear. This truck has never been off road and it's already costing over $3000.00 Plus $1700.00 for new tires. Better have deep pockets for one of these money pits.

 

Huutch98, Yes I have used this with inline pumps as well. The nice part of it is the inline pumps are not normally good pulling pumps so niether pump has to work as hard. I have mounted the Holley about 3 inches in front of the crossmember in side the frame.

 

rimesm,
I ordered that Holley 12802-1...did you use the pressure regulator that comes with it or just the pump??? Thanks!

 

Thanks, I will add a fuel gauge to watch the fuel pressure. I plan on doing a bunch of work to it. at stock I am told right now as the truck sits it gets about 19mpg. I am going to add a banks boss hoss bundle with the six gun tuner. Then I am wanting to put smoke stacks on it. I am wondering what my mpg will be if I change out the head studs with arp head studs and put a twin tubro system on it from ats diesel. I know after i put that on i will need more fuel so i am looking to also put the fass system on there also.

 

tburke & CumminsMan,

No, I do not use the regulator, but you will find it is more expensive to get it without. I do recommemd to run it off of a relay controlled by the fuel pump wiring for the factory transfer pump.
I would not expect fuel mpg to increase, not sure. I just started dealing with Quadzilla Performance... you may want to give that a look the Adrenaline w/ Pulse Kit (180hp). Best Bang For The Buck I have found. E-mail: adventurer440@hotmail.com

 

i have a 99 3500 dually 5.9 Cummins turbo diesel. When it sits like over night it is hard to start but once it starts you can cut it right back off and it will start right back up fine. You can even start it up cut it right back off and let it sit for a couple of hours and it will start right back up this is in North Carolina so it is not cold here right now. Is this something else or would this inline fuel pump do the trick
thx
