D7E filter housing problem

What are you getting for fuel pressure?
Pressure relief valve is in connection to transfer pump.
Which fuel filter gasket is blowing, top or bottom.
If bottom gasket the flange is noted to get bent if bumped or over tightened. The housing is made of aluminum if I recall correctly.
Same goes for the top flange, can get warped.

Top one. Bottomn is fine. Just surprised me that it just happened all at once. Do the top plates warp or whole housing?

Idk can’t run it long enough to check fuel pressure it’s spitting it out everywhere on the top flange.

If there is allot crud in the system then the relief valve must be stuck shut or crud got in the tube to the injection pump and plugged it. The relief valve is down on the transfer pump.

Kinda what I am thinking. I will start there tomorrow after work and pull it all out and clean it and put it back.

Do you have a first stage filter before the transfer pump? Check that too. That should have kept the heavy scale out if its in good condition and working right.

Ton of fine rust made it through into secondary housing.

To fine for the Rock stopper on the primary.

Ten-4, hope you get it cleaned out.
