Went off-roading a few months ago and on an extreme angle I think sucked some air. The truck never died but sputtered for a while. The rest of the day it would intermittently
sputter again on angles. Drove it home with a slight lack of power due to the sputter. Came home, change the secondary fuel filter and bleed all the air out and it ran fine. Drove it for a month and the only problem is sometimes it would loose prime. Pump the primer a few times and everything ran perfect.
Today the sputter came back and wouldn’t go away. Here is a list of things I’ve tried.
With engine running, bleed all the fuel lines that are after the lift pump. Two on the filter housing, inlet into the IP, IP return line. Clean fuel came out with no air
Pressurized the fuel cap and checked for leaks where air could be sucked in. No leaks
Changed the lift pump
Ran the truck from a 5 gal can of fuel
Cracked all the injector lines with the engine running
Checked the IP timing
Changed the secondary fuel filter. Cut the old filter open,
looked good.
Filled the passenger fuel tank to the very top. This is the
tank I am using
Tried using the driver fuel tank. Same results.
I drove the truck about 20 miles today. I held the pedal to the floor for about ¾ of a mile to try to get all the air out. The sputter happens at idle and while moving. I don’t think it’s a cracked feed tube in the tank because both tanks have the same results and there is a strong spray of fuel when the bleed fittings are opened while the truck is running.
