Ok, we've all seen the posted problems with fuel cell foam and pump gas (or whatever you attribute the problems to). I was working on getting my used fuel cell into my truggy, and took out the foam that was in there from the p.o. The bottom looked like it was liberally sprinkled with coarse black sand, particles of the foam that was in there. The sock would probably keep most of the problems at bay, but not what I want to trust or depend on. I've also seen where people run quart oil cans with the top and bottom cut out, and packed into the tank to act as a baffle. And, I saw where a guy had cut up some plastic pipe (I believe it was something like 3" PVC?) and stacked in standing vertically like a 24 pack of beer cans on its side. Question is, will common PVC stand up to constant and long term emersion in gas? What other solutions do you guys know of other than "build a baffle". That's certainly an option but I really don't have equipment to do a good job in aluminum, and don't feel like building a steel tank at the moment. And putting a steel baffle in an aluminum tank has it's own issues, so I would rather avoid it... This is not about keeping fuel at the pick-up point, baffles alone are really no good for that anyway. It's only about fuel slosh and aeration control.
