Re-power anyone??

big hoss with injectors

I am wnating to know if there are new Cummins #'s for the lift pump. I don't want one that has been on the shelf for 3 years, you know what I mean. This is lift pump #6. Anyone out there that can help?

Thank You ;)
 
My suggestion would be to forget the factory, Cummins, etc. lift pump and go with a RASP. The RASP is a mechanical fuel pump whose fuel pressure is dependent on RPM. Therefore, no WOT loss of pressure. I have rock-solid 15 psi all the time, including WOT. You can even "tune" it for the pressure you want. It is a little pricey, but being that you have gone through five lift pumps already, I think that a RASP would a least be worth a look.
 
I have a 2001



























































I have a 2001 diesel. I installed the BD Power auxiliary lift pump. Went 5,000 miles after installation and OEM pump failed. It kept running until I had the spare OEM pump replaced for $90 (Labor takes about 1 hour). OEM Cummins pump costs $140 and is easy to replace. With two pumps and a fuel pressue gauge you will never have an expensive fix. Check out the aux. lift pump kit at www.dieselperformance.com/ram/index.php (just click on Lift Pump Kits)

there is now an updated kit from dodge to switch to the in-tank fuel pump like the 05's have... i believe the kits is also for the 2nd gen 24v's

Not trying to start a war or anything but the only 2 disadvantages of the RASP in my own opinion is 1. It is pricey, but after going though that many lift pumps it may be worth it in the long run... 2. You still need somewhat of a good LP to prime the system back up after a filter change or if your RASP would fail (chances are very unlikely) the pressure switch would then kick in the LP so you wouldn't be stranded...



I have a FASS II LP that installs near the tank and at idle I have 16-16. 5psi and WOT it drops to 14. . And as soon as you let off the throttle even a little it jumps right up. I love it and its cheaper then the RASP. . Right now that is probably the most reliable system, but then again as far as electric ones goes you don't hear that many complaints on FASS, Airdog... etc The only issue is if that pump would fail on the road your VP44 will probably not be able to pull throughout the aftermarket pump. . Basically do a search and see what would be the best for your truck... They each have advantages/disadvantages

I know I have been doing a lot of reading about the new in tank pumps and I would not waste my money on them just because the pressures are horrible. . It drops to 0psi really quick. . Dodge says its alright with the flow it puts out... but they also said that about the current engine mounted LP. Do some research on this as well in case I missed a post... I know someone was going to test the flow rate of the news ones compared to the older LP. .



My FASS II is rated at 95gph so i know there is plenty of fuel getting to the VP 44 & keeping it cool... .

I would say that my setup is vastly superior to any electric pump. And, with the price that these AirDogs and RASPS are going for, I was able to put a cam in and fix my lift pump problem for good.



Not to say that you aren't correct in your statement. But, there's always an option.

On edit... BTW I was about half a step away from the RASP when I heard of the cam option. IMO NOTHING compares to the reliabilty of the RASP when compared to ANY electric pump. Besides, the factory stocker will probably last a million miles when run with the RASP.

I hear ya. They are definitely pricey... definite disadvantage. I will certainly agree that anything beyond a stock lift pump (FASS, Air Dog, regular old pusher, RASP) is better than nothing. The mechanical reliability, fact that I could have a back up LP, and higher fuel flow at higher RPM is what did it for me. I'm not saying it's the best option for everybody, but I would highly recommend it.
