If that gas was bad it's all bad!

I would lose the big filter, that's beside the main pump under the car!
This will also help clear the main pumps suction side of junk coming from the tank line. You pull the whole tray out as a unit to get at it.

Warning! The filter is a bear to get loosened and has to go back as tight not to leak. Use new copper gaskets and an impact if necessary.
Most likely, it may have been change once in the cars lifetime.

Out of sight, out of mind, rules are in play there!

Drained is an open statement of how?
Don't know if you dropped the tank and inspected it. I hope you did!
Did your tank have the screw in the bottom? I have seen some and that leaves trash let alone a clogged inlet sock!

Move to the FPR or at least the return hose there, going back to the tank. Blow air from there to the tank or best the other way around, if you can still access the Hose?
If not, the wee bit that goes back into the tank, will most likey be dissolved into several fresh gallons.


Next, bleed the fuel rail by jumping the pumps at the fuse panel. Run them until all is clear as some new baby oil in your catcher.

The whole jest of this, is to rid the system of as much of the old congealed fuel before it hits the injectors. Hopefully that's not too late!
If not you will be cleaning a screen or a pintle or two.

Seal it all back up and that should help cut down on many, many problems.

Best thing to do next is....Drive it more like you own it. It pays back dividends, in reliability!
