So the first thing that I looked at on my Delta was the inside of the gascolator.
Sure enough there was lots of debris in the bottom and on the screen.
It looked sort of like little fragments of jello.
After removing the fuel filter it was found to be severely restricted.
I believe that the new auto fuel formulated with ethanol is causing my fiberglass fuel tank to slowly disintegrate.
When this fuel tank was first constructed in 2001 leftover pieces of fiberglass samples were submerged in fuel to test its long-term effects. Those pieces are still in tact, but that was the old fuel with MTBE.
The fuel tank is being used to test the new formulation and it appears that it is failing.
Next project … perhaps an aluminum fuel tank.
Well back to the drawing board.
