Is it the current wisdom that the mechanical fuel pumps, now made
by Moyer Marine new or rebuilt with new diaphrams are superior to
the electric fuel pumps?
I converted my engine to a electric pump 10 years ago, not from any
difficulty, but listened to caviats about diaphram failures pumping gasoline
into the crankcase. Initially I had some difficulties with overheating
faucet pumps, but that was solved. I then have ran better than 8
years without problems - that is until this year.
I spent a month tracking down shutdowns, the final outcome was that
it was probably due to pinhole air leaks because everything else was
swapped out, hoses, pumps etc.
The electric is pesky to prime, even with the bulb, and seems to be more
failure prone.
I am wondering if, with the improved moyer mechanical fuel pump,
it is better to return to the mechanical pump?
One reason I mention this is that a respected Atomic 4 expert has
reverted his engine back to a Moyer Mechanical pump.
What is involved in reverting back to the mechanical pump?( I have
no reason to believe there is any problem with the engine section
other than reinstalling parts.)
