Either my oil pressure sender failed or I've lost all oil pressure!

I had no problem at all finding one, wish. The first place I went to (dare I admit it?? - AutoZone!) had it. The brand is "GP Sorenson".

I'm no TQ expert like Demonsizzler, but from my limited experience the most troublesome parts of the carb are the O-rings at the bottom of the main fuel wells and the metering rods and jets. The rods and jets had greenish crud all over them from gas evaporating in in the fuel bowl, and I'm sure that the crud was interfering with fuel flow. The most difficult part of the job for me was getting the metering rods to go into the holes in the step-up piston rack while at the same time getting them to go into the metering jets.

It's really a cool carburetor, though. The only way Carter could flop open those big air doors to the secondaries to achieve the TQ's 850 CFM rating without flooding the motor is to very carefully control the mixture when the secondaries open, which the step-up piston assembly does very well. And the fuel never comes into contact with any metal that conducts heat from the engine, so it stays about 20 degrees cooler than in all-metal carbs.

I have 3 Mopars with TQs. Once the fuel bowl cracked on one of them. I sent it to a plastic "stitcher" (repair company) and when they returned it, you couldn't even tell where they'd repaired it, except that they reinforced the area that broke. So it's really no problem keeping the TQs going.
