By now your stock lift pump is probably worn out, If you have turned the fuel up on your pump I can just about guarantee your fuel pressure is being pulled down to 0psi under hard runs. This cause extra wear on you pump and also does not allow it to advance the timing like it should. To fix this problem you can get a low pressure piston lift pump that will be set at the correct PSI and not need the regulator. It is a great improvement over the diaphragm lift pump the 1st gens came with. The piston lift pump gives you better pressure and should support you past 350HP, also if the diaphragm in the stock pump breaks you run the risk of filling your crank case full of diesel fuel.

Here are the parts you need and the part numbers in a picture that David BC847 took.



Your going the need to trim the insulation off the side the block to make it fit but other then that its a direct bolt up.

 

Here is a writeup written by David on how to install the pump.

how much did the pump and line cost you

 

And the pressure that this is pumping is safe for our injection pumps?

I just might have to do this while the motor is sittin on the floor. Definitely a good thing to do to reduce the possibility of havin to get under the hood after the performance mods.

 

WITH THE LO PSI SPRING YES

 

So the FASS DDRP would be a good canidate fer my 1st gen or just go with something at the parts store

 

Depends on how much power you want to spend, the pump in the 1st post is good for 350-400hp

 

and go with the airdog over the fass IMO

 

so if i go to dodge or cummins and order that pump with that part# will that be the low pressure lp, or will i have to do some mods to it? what kind of money to do the swap?

 

THOSE numbers are for the low pressure pump. There is a HIGH pressure pump that comes stock on teh 2nd gen trucks. Go to a Cummins dealer, be cheaper.
