<VV> "Screwed" fuel pump

My leaking fuel pump problem was solved by using longer than standard bolts
that extended through the bottom of the housing, and then putting
lockwashers and nuts on the ends to increase the clamping force.

There  was some discussion on warped castings some time back.  You might
one of these.  The fix was to take the pump apart and using a  large file
flatten (true up) the gasket surfaces.

I don't see why  you couldn't use locktite on the threads of the screws.

You might want  to contact the vendor that sold you the pump for

Good  luck

As I recall, Keith, the usual problem is not the screws loosening up, it is
the gasket material squeezing down in regular operation, allowing leaks. You
are  not re-tightening the screws, your are tightening them further in. If
loctite the screws down at first installation, it might limit the later
"adjustment" tightening down. What you might try, if the vendor doesn't have
better suggestions, would be to true up the gasket surfaces and tighten the
screws. Follow up later with another tightening. After a period of time, if
 think the screws are backing off, then you could tighten them down and
loctite  them. You will be tightening them onto an already compressed
gasket.  -
