You'll probably have to settle for used. What's wrong with yours?

Re: NEED NEW SENDING UNIT!!

It's rusted and ruined. I fixed the gas tank and coated the inside, but the sending unit is ruined. Any suggestions on where to find a used one?

Re: NEED NEW SENDING UNIT!!

That seems to be the right part. It is the part that fits in the tank and reads the fuel level and sends it to the fuel guage in the dash. I have a 350 V8 5-speed tran.

It wouldn't have had a 350 from the factory, but it might have one now. Wouldn't make a difference, just use the 305 part.

$200???

As that site shows, the same part was used for V6 and V8 cars.

I'm using the original V6 carb pick-up and fuel lines for my 350. It's all 3/8" stuff.

I can't imagine paying $153 plus shipping for that part. Check the classifieds here.
