Does your mechanic know that the pump has to supply at least 50 psi
working pressure?

The standard pump pulls fuel from the tank very nicely -- it's a
positive-displacement pump and would likely pull at 100 psi except
that gasoline vaporizes at much less pressure.

On the gasoline tanks there's a filter "sock" over the outlet line
inside the tank which can get clogged.  I think the longterm solution
is a new tank, but blowing compressed air into the outlet can blow
some of the crud back into the tank.  I strongly suspect that this is
your issue.
