What Is The Best Electric Lift Pump For 3-375 Hp And Do You Remove The Mechanical Or What. What All Do I Need To Do To Install It.

 

what makes you want to go to an electrical pump?? for that power you would be fine with a piston lift pump JMO.

 

Ok So What Is The Best Piston Pump Im Looking For Relibality And Consisant Fuel Pressure

 

The piston pumps are all reliable. The old standby "1st gen" lift pump will supply mid-300's no problem if you upgrade the fuel pick-up.

If you want to go electric I recommend the Walbro 392.

I still have the piston pump on my truck, the two pumps work in parallel.

 

Wanna, explain " Parallel ".

 

Sweet Does Any One Know The New Cummins Pt # For The Piston

 

The output from the Walbro feeds into the tapped banjo bolt in the filter head inlet. So with the Walbro turned off the piston pump feeds the truck.

 

So both feed the same location on filter inlet? Do you have a special fitting on it? Could I do the same thing with the stock lift pump or would it back feed the stock pump?

 

Yes, they both feed the same fitting. The mechanical pump feeds through the banjo fitting, the Walbro feeds right in the end of the banjo bolt.

The banjo bolt is 1/4" NPT tapped, I got it from Glacier Diesel.

Mechanical lift pumps all have a check valve on the outlet, so this will work with a stock pump or a piston pump.

I like this setup because even if one pump fails the other will get me home.



The hose from the Walbro comes in from the lower right corner of the pic.
