On mine the one way valve has failed. Likely caused by dirt, I'm told. And
it so happens to have coincided with the internal filter braking off. So
I'm not keen on the same happening to the expensive replacement I have
waiting to fit.

Totally agree with your logic, no knowing what crud is in an old tank or
may fall in later.

Would a Y-strainer suit you? I thought of the CH ones that BES do but
who knows if the sealing O-ring would be fuel friendly. Here's one that is
fuel rated and only a fiver but it's 1" BSP, second item down:

Hopefully some kind of fuel hose adaptor could be found or fabricated.
