Hi guys. Working on my son's 1997 F250 7.3 diesel. It quit while driving down the road, like it was running out of fuel. Checked fuel pressure at the schrader valve, zero. I removed the fuel pressure regulator and clean the screen. It had a lot of trash on it. It took a lot of cranking but it finally started. Only has 10 psi of fuel pressure at idle and will only build up to about 20 psi at 2500 rpm. Very sluggish and low on power. I'm thinking the fuel pump is failing. Thanks.

 

It's probably a stupid question but did you replace the fuel filter. What did it look like

 

Replaced the filter. Old filter was only 5k miles old, bowl was very clean. Thanks.

 

If the truck runs the same on both tanks, I would say you are on the right track with the fuel pump. If it runs like it should on one tank and not the other, I would start looking for a hole in the fuel line from the tank that it runs poorly on.

 

Replaced fuel pump. Got 60 psi at idle now, runs great! Only problem, plunger and nose of pump broke off and fell into engine. Rotated the crank till I heard it fall in the pan. The sump is pretty deep, hope it stays there!

 

I have read before that you will be OK but don't know for sure.

 

Get an industrial magnet, get the magnet to pull the broken piece into a corner until you change the oil pan gasket.
