Re: fuel pump...maybe
 

So now fuel pump #2 is installed...

And, in the meantime... the check valve on the brake booster went bye-bye.
But that fix was (so far) easy enough... not much more exciting than a suddenly dead brake pedal !:ahhhh:

On to the next task...

Re: fuel pump...maybe
 

FYI: Carter has discontinued the M3987 fuel pump for the early 305 V6 engines, a company in Texas has three left, you can Google them. This pump is better quality than the Airtex.
When I received my 1961 4WD GMC Suburban the gas gauge did not work. I dropped the tank and removed the send/pickup unit, the float had filled up and the thin brass conductor was broken. I installed a new float and solder the brass connector. The tank was perfect on the inside, I went ahead and coated it so I would never have a rust problem in the future. The pickup did not have a screen on it and I left it with out one. There is a paper cartridge fuel filter mounted on the frame rail, which is available from most any parts store.
