Dump HPOP question
[What does it pump or diesel. Yes diesel is an oil does it pump diesel?
Reason i ask is i am replacing the o rings $1.01 each at international. While it is draining i see motor? Draining out of the ports. Is this an indication there is other issues?
In advance

HPOP is a high pressure oil pump, that pumps motor oil (not diesel fuel) at high pressure, which is used to fire off your diesel fuel injectors.

Ok got it
Another ? Why was fuel consumption so high 1/4 tank for 10 miles did it just dump the fuel into the cylinders? Oil level is ok i do not see where oil has dropped that much
I assume i will need and oil change now correct?

Diesel usage wouldn't have anything to do with the hpop. Are you sure you didn't blow a braided fuel line?

I think riffraff has the braided fuel lines. I know they have the high pressure oil lines. You can send Clay an email or call if you can't find them on his site.

I believe I have my fuel lines in the shop if you would like. I converted to electric fuel so have no need for them. Of course no guarantees, they had 150k on them, but didn't leak at all.

I don't know if you have enough posts to pm me, but if you are interested and can't, email me. 427fordman at No spaces in the address, and at replaced with @. I can send them out monday.
