Hey guys and merry Christmas!
So a couple weeks ago I took off my mech fuel pump and put a e pump on. I installed it in the engine bay and not back on the frame so it pulls instead of pushes. So here is my morning routine since install. 1. Pop hood 2. Grab half empty can of starting fluid 3. Turn switch on so the pump runs 4. Go to the fuel filter Schrader valve bleed air for a sec 5. Release and do it 2 more times until fuel squirts out 6. Spray start fluid 7. Floor the fuel and pray it starts 8. If it doesn’t start it will fire off for a split second and die 9. If #8 happens bleed fuel again 10. Most of the time batteries are tired and it’s not gonna happen. 11. Wake wife up give a choice to either drive me or be without a car for the whole day 12 if truck fires off and you get to work park the truck shut it off 13. Pop hood 14. Turn switch on so fuel pump runs 15. Bleed until fuel squirts out 16. Wonder why you replaced the mechanical pump cause this is worse than before.
The truck is a 1994 f250 7.3idi turbo. 281,000. The rear fuel tank leaks and I only use the front. It’s a project plus a daily driver any help would be appreciated
Like the prior posters said, you have air intrusion. Finding where it's at is the hard part.
If you're not interested in doing the diagnosis, your first stab in the dark should be to install a return line kit, new olives on the fuel lines, and replace the check valve on the filter head. Also install a new filter return check valve # F2TZ9K061A, or cap it off and eliminate that line.
If after all of that, you're problem persists, you'll have to use clear vinyl tubing from the hardware store and find out where your air is coming in from.
Did you have air intrusion issues before your pump swap?
