Blitz fuel tank switch sucks air

[Ganmain Tony]

Chris, not trying to be condesending...but lap means - to grind (finely) the surfaces between the the feul tap and the body of the fuel tap it sits in.

It makes both surfaces sit evenly against each other thus preventing a fuel leak. As Mike has suggested, valve grind paste should work well.

Doing this should provide a pretty good seal. It may still weep a fraction initially but should "Take up" after a while and stop leaking.

Good call, Tony. We take these tasks for granted, I mentioned polishing paste, only to finish off or if the fit was not bad enough to require use of a fine valve grinding paste.

And to answer the other part of your question, Chris, the taps are available NOS from Dirk Leegwater as Ford C11Q-9285 & C011D-9287.

Your F15 would still be under warranty, wouldn't it?

Not sure Tony, I think the Aussie rebuilder only gave a concrete warranty: once it's off the concrete, the warranty expires. Or was that a '12-12' warranty: 12 inches of forward movement or 12 minutes......??
