Hi Dave, I had to replace the lift pump (might be called a transfer pump)
because the diaphragm was leaking and I couldn't get a diaphragm and that
cured the worst leak. Next I'm going to replace the crush washers to try and
cure some minor seepage that still exists. When my lift pump was leaking
you could see the drip but I was able to fit a margarine container under it
to catch it for short term.
Cheers,
Tom S

From both pumps oddly enough....
Lift pump seeps, appears to be gasket and or crush washers on banjo fitting.
I’m wondering whether in addition to replacing the gaskets I should also
replace the (still operating, likely original) pump for reliability’s sake.
Thoughts?
High pressure pump has very minor seepage as well. Can’t see what’s
causing it. Any likely scenarios?
Many thanks!
