My 2QM15 is not getting fuel, It gets to the lift pump input but no
further. I just had the fuel polished after some crud problems, so likely
either there's crud blocking the diaphragm hole, or the new additives made
the 42 yr old rubber diaphargm "retire".
Some years sgo there was discussion abo
that feed fuel line? I think I

Joe, I like the remote fuel pressure gauge! That looks like aviation or race
car technology. Tom is trying to find out why he can’t get that last 15 gallons
of fuel. I believe Josh has the same Yanmar and believe he posted his vacuum
numbers so there is something to compare to. He can also shut

So, if I understand recent responses to my recent post on running out of fuel
at less than an empty tank, the theory is that with a weak fuel lift pump at a

Vacuum gauges are useful, but they only tell half the story. No vacuum
can indicate all is well or it can indicate the fuel pump failed. The
engine - gas or diesel - could not care less about vacuum, it wants fuel.

Tom, it’s your boat and wallet but an inexpensive vacuum gauge will tell the
tale. I would hate to buy an expensive Yanmar pump and find out it’s something
more simple unless you want a spare pump anyway. They are available on amazon
or eBay and maybe 20$

I had a similar problem with the lift pump on my Beta 28. The tank location
compared to the lift capability of the Beta was marginal, even tho the lift
pump was working ‘fine’.
My diesel mechanic recommended bypassing the mechanical lift pump and using an
electric pump. Installed it with a switc

So, if I understand recent responses to my recent post on running out of fuel
at less than an empty tank, the theory is that with a weak fuel lift pump at a
certain fuel level in the tank, the pump would stop lifting fuel, thereby
causing the engine to run out of fuel.
So, guess I’ll take a sho
