[NSRCA-discussion] Bad fuel

I had that problem too so I don't have a filter, weight or anything metal
inside the fuel jug.....I make the pickup line long enough so that it curves
around the outside wall of the jug. I cut a V on the end of the pickup so it
can't suck to the wall and then use a filter outside the jug and again in
the model.

I had the same problem. Cause was the corroded brass pickup. I've now
use only the sintered bronze pickup from DuBro. The only problem with
it is that it still has brass tubing but that could be covered by fuel
tubing. Still need to check it once in awhile. Dwayne
