Results for "National Dolphin"

Found out my RV service tech wants $800+ to replace the entire grey water system on my 2007 RV for an intermittent blockage that seems fixable. It doesn't seem to matter if we're level or not - it's completely random.

I've tried using a high suction shop vac and even attempted snaking it, but I'm nervous about forcing things and making the problem worse. I suspect it might be a manufacturing plug that fell into the tank, but I'm not sure. I found one solution with a reverse flush valve that seems to work temporarily, but I'm concerned about the underlying cause.

My 1994 National Dolphin with Ford 460 ran like a champ to the campground, but after 4 days of living the good life, it decided to throw a tantrum when it was time to leave. Engine turns over fine but won't fire up - classic "I don't wanna go home" syndrome. Throws some starting fluid at it and it runs briefly, so I'm thinking fuel delivery issue.

Checked the fuel pump and sure enough, zero power getting to it. Being the resourceful newbie I am, I ran a jumper wire directly to the pump and made it home just fine. But I know this isn't exactly the "proper" long-term solution my wife keeps reminding me about. Where should I start troubleshooting the electrical issue? Is there some safety switch I don't know about that might have tripped during our stay? …more
