Factory Lift Pump
 

I just picked up a 95 2500, it still has the factory mechanical lift pump. Does anyone know what kind of pressure,this thing pushes? How much pressure can you push thru the stock filter housing, to the p7100?

Well I guess no one knows the answer to my question. I see there where alot of views but no replies, not even any suggestions. Any help would be greatly appreciated. If I don't reply back quickly, it's because I'm out on the road, and I only get to look on here every three days or so. thanks in advance for the help.

Stock, it should be around 20 psi at idle, and something like 35 at 2k rpm with no load. I have mine at 40-45 at idle, and it holds the same at speed. No leaks out of my filter housing.

Thanks for the info.
