This problem is starting to get on my nerves. Almost every time I get above 3200 rpms the engine runs out of fuel and not just the same one. Fuel comes from same tank. thats the only thing they have in comon. Changed water fuel seperator filters upteen times. Removed all fuel and cleaned tant best I could. Looked in tank with fiber camera and tank looks clean (now) changed to different pickups it has 4 options. no change. Any ideas would greatly apreated


ps the tank had some old rusty fuel gauge sensor parts and three foot rubber hose and a lot of gritty crap removed all that I possibly could. Now the starboard engine after running for about 5 minutes. stalled out and restarted would go any more than 1500 rpms without backfiring and stalling out no fuel. Replaced liftpump about 3 hrs on it

sounds like the fuel tank isnt vented,or there is an anti siphon valve in the gas tank,,,search anti siphon valve

If you had rusty crap in the tank from a deteriorated part, some of that could have made it into the fine filter screens in the injectors themselves. Fuel is a pain if not properly stored and cared for etc...

not 100% sure but someone else had mentined there being a filter down by the cool fuel setup.

antisiphon valves checked and vent checked even ran with cap off still the same thing. pulled lift pump off crap in the screen. Cleaned waiting to try' is there any other filter other than water fuel seperator filter in this system
