The rubber fuel line from the tank to the pump has been soften by ethanol & the pump can collapse the fuel line as the RPMS increase. Replace the line.

Line was replaced... new lines from fitting on top of tank to the pump. The only part that has not been addressed is inside the tank. I tried when replacing the other lines last year to access the pick up in the tank and was unsuccessful. The fitting on top of the plastic tank was far too tight and I feared breaking it...

Sorry, didn't do a good job of reading. The fitting at the top of the tank has a spring and ball in it, if there was debris in the tank and could pick it up and clog that fitting so that you are not getting full fuel flow.

Yes, the ball fitting is the anti siphon valve. This was first cleaned...then removed for testing.

DOes anyone know if there is anything in the tank (like a screen or sock) that could be causing the problem?

Has anyone had success removing the fittings and pick up tube from the plastic tank?

Thank you,

Thank you,
If I am thinking about the correct year model, yours being an 86, I think there is a screen on the end of a straight pickup tube that is in the fuel cell. I'd have to see a photograph of the assembly to be sure. I took an older model apart just a few months back.

There is a fairly recent thread here about the fittings and someone's mod to a fuel cell to make it work....tutorial with photographs.

Check every hose clamp on the fuel line assembly for tightness.

You can run a straight fitting without a ball / check valve. It won't kill it. I have done several this way. Still working like a Timex.

Yes. The long (pick-up) tube in the photo had a fine-mesh screen attached to the bottom of it.

While my tank is plastic, I have a feeling that this is the issue. Has anyone had success removing and inspecting the plastic tank pick up?

I have tried to remove it and was worried i was going to bust up everything. When looking at your photo, I think I may be able to add a bit of heat and a larger wrench...
