My belief is to never mess with old metal castings unless absolutely necessary.

Well - I had to rebuild the fuel pump (used a kit from Zip) as the internal oil seal was suspect but most likely the cause of my oil leak was the push rod plate gasket - replaced all of it... Diaphragm spring seemed weak as well - replaced with the kit spring.
Apparently, from sitting in the body shop or for some other reason, enough moisture was in the pump to leave rust stains... The diaphragm mating surfaces weren't all that flat either so I dealt with that.
Pump is in and works fine and leak free, however while running the car on the lift I heard this little bird chirp, not sure what it is or if it had been there before - its louder from underneath the car on the lift. It almost disappears when the car warms up - something rubbing the timing cover ?
I can't imagine its anything to do with the new fuel pump - nothing of a metal-to-metal nature moves in there other than the push rod/pump actuator arm which were greased before the install.
Guess I'll loosen the fan belts and do a short run to see if the noise abates but I'm thinking that's not likely...

I agree and thanks....
Got new belts this evening and will just go ahead and replace them - they're about 7 years old (or more) anyway

Well. L8DYBRD has a 5 speed “tranny”
Do I have to explain that ?

It was the belts. New ones installed and no more noise. Should be ready for spring cruising now.

Frankie, after running a short time re adjust your belts and you are good to go. You loose some tension as soon as they rotate the first time.
Boroughs makes a belt tension gauge that will show you this if you choose to test the theory.
The belts will quickly lap into your pulleys and sink a little in the V grooves after initial start up reducing tension.
Slipping belts will glaze over and then they chirp or squeal leaving you un happy.

Yup - I've always rechecked fan belts after replacing within a short time of running with them...
The car actually is idling better with the rebuilt pump, can't explain it but its a noticeable difference...
