Correct, I know it's before the filter AND always has to do with HEAT. Anyway, it's a lot easier to go for a cruise on the highway and get it good and hot then come home and hit the fuel pump with a garden hose than it is to change the fuel pickup to a gas can. So if the garden hose doesn't stop it, THEN I'll do the hose in a gas can. When going by the process of elimination, one can also logically do the easiest test first.
