Thanks Josh you are right the gauge measure inches of mercury not atmospheres.(
.489 vs 14.7 lbs) I did an experiment this morning and our Universal M35 uses
an electric fuel pump made by Facet that runs at 6-8 psi. The gauge running
shows 1 inch of mercury or just around .5 lbs and it will
I'm pretty sure my gage reads in inches of mercury. 29.92in-hg (30) is
generally considered a perfect vacuum (1 bar, -14.7 psig, 0 psia). As I
recall my normal running vacuum with a clean filter is about 6 on the
gage. The arbitrary green band runs between 0 and 10. Yellow is 10 to
15. And

The electric lift pump on mine pulls 1 atmosphere of vacuum and Josh’s yanmar
pulls 3 or 4 if memory serves.

When you say ran out of fuel do you mean the level of fuel in your fuel
filter dropped below the outlet?
Which Racor? A 500? If so, check the gasket and check the top for
warping. A warped top may not seal properly and may begin to leak when the
fuel level gets down to 1/2 tank or so.

Tom, I think you have an issue with fuel lift. Either there is a hole in the
fuel pick up at the 15 gallon gallon level in your tank or the lift pump for
some reason isn’t able to pull fuel all the way from the bottom of the tank. If
you had crud and your filters were getting clogged a fuel
My first thought is, why not polish it? Diesels like fresh clean fuel.
My second thought is to check if your pickup goes all the way to within 1/2” of
the bottom of the tank.
Is the pickup on one side of the tank so it’s sucking air when you’re heeled?
I’m having a similar issue with a boat I’m
I have a weird issue. 2x last year a ran out of diesel and needed
only 25 gallons to fill my 40 gallon tank.And, yes, I made sure it
was topped off. I pulled the pickup tube to see if that was the
issue, but it was solid straight and clean. In fact,
