[Healeys] fuel pump filter

[Bob Spidell]

FWIW, I have no filter--besides the thimble-shaped screens in the carbs--in my  BJ8 and have run over 100K miles with no 
issues attributable to a lack of filter.  Make sure your fuel system--esp. the tank--is clean and rust/crud-free (use a 
good sealer if you're so inclined).  If you have a lot of crud in your fuel system the filter will eventually plug and 
you'll have problems anyway.

My theory--and it's only that--is that the passageways in an SU fuel/carb system are so (relatively) large that anything 
small enough to pass through the screens in the carbs and fuel pump will not cause a problem (not the case with a 
modern, fuel-injected car).   I guess one of the transparent, plastic filters would allow you to see if crud was coming 
through.

I opened a fuel filter from my Ranger with 100K miles on it and except for a few small black flakes--which I attributed 
as shed from the black plastic tank--the filter material was clean.
