Hmm, I was thinking about going to hard lines!

That shouldn't be a problem. I like to to use hard piping for most of
the fuel system but if I had to do it over again, I'd probably use flex
hose for more of it.

It wouldn't hurt to check the vent, as somebody else suggested.

One benefit to putting a bypass on the pump is that you can also tee in
a manifold to use the pump for polishing and transferring fuel as well.
That is my plan, I put in the tees but not the pump. I'm going to add
another set of tanks (probably flexible bladder type) in the
not-too-distant future. Add in some gages, too.

I'd like to have a fuel scrubbing system. Have you seen these fuel
monitoring systems that measure fuel flow and fuel return to track
fuel usage. I read about them a few months back and I'd like to
find out more about them. I don't want to be wondering how much
fuel I have.

There are a couple of benefits: greater flow is one, more compact, more
resistance to various kinds of stress, less prone to leakage in places
other than fittings... the down side is that they're more difficult to
fit, and you can't pull them out of the way to work on something else.
Over years, the hard copper pipe will work-harden with vibration and
become impossible to keep tight. The copper pipe I put in is mounted so
that (hopefully) the vibration will be minimum.

Me too... it's on the list, along with many other upgrades

Yep... a lot of control systems we work on have some fancy fuel flow &
fuel consumtion/efficiency packages.

In industry, Siemens and ITT are about the best IMHO. For boats the
FloScan is popular and seems practical. I know a number of trawler
owners with these

You'd need a flow meter hooked up to a totalizer. Really, that seems
like overkill for our boats. A good reliable tank level gage should be
fine... most are cheap junk, like the ones in cars... better than
nothing though!
