Vega friends,

I have an outboard with two fuel tanks and a central water filter. I believe I've gotten an air leak in one of my lines either between one of the two tanks and the filter or between the filter and the fitting for the line that connects to the outboard. When I tried to pump fuel up to the outboard, I got nothing. I tried two different external lines with built in primer bulbs; neither worked. When I attached one of them to my portable auxilary tank it primed right away. All the fuel lines run under the deck.Any ideas?

Attach the portable tank to the next join away from the engine to see if it runs , if it does move away to next join and continue step by step approach until engine fails to pull fuel through. There is your problem. I once had a persistent air leak that I couldn't seem to solve but by adopting this method eventually showed me that the air hole was in the fuel pipe inside the tank and once identified was easily cured.
Hope this helps
Mike
