[QUOTE="Big Bore, post: 144083, member: 760"] Update. Did a little investigating and the AD fuse was blown ( it's a old style glass fuse????? took me an hour to dig one up since I've gotten rid of all my old junk, wife had to remind me of the old camper lol). Replaced fuse, pump came on, then blew fuse again. Replaced once more, same thing. Already checked the AD harness and pretty sure it's good so not sure what else would cause the fuse to keep blowing. Going to dig up manual and see what it says. So, that means the Walbro has been sucking fuel through the AD for who knows how long. I'm sure that's what killed it. So now I get to pull the AD and bypass it till I figure out wth is wrong with it. If it needs a new pump, I'll prob turn it into a filter head for my fuel bowl delete, if possible, and move on.
