Well I went and screwed the pooch. I dropped my pick-up saddle tank and installed a 31 gal TBI Blazer tank as part of a fuel injection swap. Long story short I bought a used tank based on the seller's word that it was clean and ready for install. Turns out the tank was filled with dried up gasoline varnish similar to a bathtub ring. Over the course of the last week and the first full tank of fuel my fuel system began to plug up. I dropped the fuel filter yesterday and out came a bunch of varnish flakes and muck. So this morning I pulled the tank and drained it, pretty nasty inside along the varnish ring and it looks like the inner tank coating may be bubbling in places. I pulled the TBI injector pod and the injector screens were clean as a whistle - no hint of orange crap. However the fuel I dunped out today looked like red sandy river water where you can see the tiny particles suspended in the fluid. When I'd pour out a bucket of the fuel it looked like a miner panning for gold. I have included pictures because I need your honest advice. 1. Should I throw the tank away and a buy a new unit or try to clean this one? 2. Considering how bad the contamination was should I replace the injectors? 3. Should I replace the in-tank pump itself, will it be damaged? 4. Beyond blowing out the lines and changing filters do you have any other suggestions? Thanks, James.
