I dropped my fuel tank to install an Aviator pump and was shocked at how much sediment was in the bucket and how dirty the socks were. It on only has 7500 miles on it and I only use name brand Premium gas,it was disgustingly dirty IMO. I fly on helecopters and our fuel filters NEVER look like that. Of course aviation fuel has to be clean for obvious reasons IMO this was ridiculously dirty fuel even for a car. I wonder if the dirt/dust could be getting in through the vent system or if if comes out of the pump that way? You would think that if we can keep aviation fuel clean we could keep gasoline a little cleaner than what mine was. I had to change my fuel filter because even though I was extremely careful I guess I broke some debris loose and clogged the filter becuse after the pump change pressure would drop almost to zero on deacceleration,changed the filter and now it works great.
