I agree with the ball check valve.
Turns a difficult job into an easy one.

Couple pics of the fuel filter in my car.
Hard to tell but the plumbing is, tank, ball valve, filter, pump.





The filter is a small Wix fuel filter.
The mount is a regular oil filter remote mount for the Fram PH8a series of filters.
Although, there's a different nipple that has the remote filter threads on one end and a smaller thread for the filter.

After I made the nipple and put it all together I find that Wix makes a PH8a size fuel filter that screws right onto the remote mount.

The Wix filter box will say "fuel fiter" on it.
Pay attention so you don't end up with an oil filter in your fuel system.
