Vapor lock? Fuel cell? Help!

[bertsdirt]

Is anyone familiar with '94-'95 GT-40s vapor locking? A mechanic at the Nautique dealer says I have to convert to fuel cell to eliminate this problem. Does this sound right to any of y'all?

Accually ther was a upgrade for the 94 where you had to splice the return line with the line between the low pressure pump and high pressure pump, but the 95 used a different fuel pump that already had the fitting built in the pump. By the way what grade of fuel are you using(octane)?

Turns out that it's not vapor locking at all. I've got a firing problem, but don't know where to start. My spark is yellow/orange rather than blue.

What did Paul say about it?

Has he looked at it?

I haven't talked to him since I discovered that vapor lock isn't my problem.
