I've asked on uk.rec.cars.maintenance without much success so fall back to
the experts.;-)

I've got a problem on the old Rover with the one way valve in the petrol
pump failing. It's a fuel injected car so has a high pressure pump mounted
underneath and close to the tank. There is a filter after the pump and a
gauze one inside the tank which I'm told often fails by falling off. ;-)
So what I need is a 1/2" fitting in line filter to go in the rubber hose
between the tank and pump - there's plenty of room for near any size and
shape within the transmission tunnel behind the pump.

I'd question the wisdom of fitting a filter in the location you suggest. At
the most you don't want any more than a strainer because positive
displacement roller cell (is this correct?) pumps don't like to suck, and
given the low vapour pressure of modern fuel it will cavitate and make
noise.

But, many manufacturers don't even bother with even a strainer between tank
and pump, so why fit one? I suspect you suspect that there's crap in the
tank? IMHO you should remove the tank and clean it out and forget about
fitting strainers.
