Before I changed the pump I'd do  fuel pressure and delivered volume tests cranking the car with a grounded coil wire.  If it tested OK Then I would make a poor man's fuel pressure gage from a spare oil pressure sender and some fittings in a modified fuel line, and put the oil light wire on it. I generally ran an oil pressure gage, but if I was nervous about driving with no oil light I'd make a pigtail so either low oil pressure or low fuel pressure would light the light.  I'd think about using an oil sender that "went off" at 1 or 2 psi instead of zero if I could find one real cheap, because gasoline ate the last oil sender I did this with.  And I'd carry tools and a 1/8 inch pipe plug to remove and block the sender if it started leaking. Oh, and I would test the vapor line by blowing in it to be sure it was not blocked.
