I bought a VIA 42 this spring and sailed it down from Halifax
. Had to get a tow the last 20 miles. 1985 MD-17D. The lift
pump was failing and had to hand pump it every hour or so, ran for a good 4 hours then dwindled down to not running more than 5 minutes. Tried to install the new lift pump, but they failed to account for the fuel
return line which feeds back into the input line. The old pump is discontinued and the replacement has the in/out put rotated and spaced different. The fuel
return was the tricking part, it doesn't go back to the tank, it goes to a double banjo on the input side. Solution was to cut the metal tube and rubber hose the gap. The main fuel line also didn't have enough reach for the new 90 degree turn. I wanted to put an aftermarket electric pump
on, but the return made it tricky and i was short on time. If you carry a spare that is not the same, carry extra tubing etc.
It has 8000 hours and will be pulled this fall or next spring for a new Beta.
Next dilemma, who wants a used MD17? Is there a market for used engines or just scrap them? Have extra (used) parts and filters also.
