Hi All, The fuel gage on my 70 Vista Cruiser went to full all of a sudden. Checked it out and the sender is open. I know this is a tough one to find but am in need of a working sending unit. It has 3 lines that go to it. 1/4",5/16" and 3/8". Thank You Steve

 

Send your unit to Tri-Starr Radiator for a rebuild.

Thanks for the information. I would like to find another unit so I don't have to have the tank out of the car a long time. Steve

 

I appreciate your position. I think Tri Starr can give you a quick turn around. If you picked a period of forecast bad weather to pull it, you would miss little. In any case if you find a used unit, you may want to have it rebuilt before installing it.

Just in case-- the symptom of "going to full all of a sudden" is so often associated with a bad ground connection for a wire leading back to the tank sending unit.

 

Thank You. If I do find one I will send it out to be rebuilt. I just don't want to tie up my lift for a extended period of time as I am always using it. Steve

 

There isn't really much to these.
I pulled mine and took it apart (A couple bent tabs) soaked it in white vinegar to eat away the rust.
Then sprayed the ends of the wires with electrical contact cleaner.
Wiggled the connections back and forth a bit repeatedly to clear the corrosion away between the parts.
Repeated the process until the unit moved the ohms meter up and down when moving the float up and down.
I'm far from an electrical guru, but this was something I'm pretty proud to have done myself.

BTW. The tank will come out with just a jack and removing the wheel. Might be easier on a lift, but doable on the ground.

 

Thanks for the information. The car season is almost done here so will do it in the spring but figured I would start looking. I put the tank in before installing the body on the frame but looks like it will slide out of there just have to tape everything up real good so I don't scratch anything.

 

It's definitely tight. I had to pry the fender out slightly. The tank won't drop straight down. It comes out towards the wheel, and then down.
Fortunately, my Crusty is pretty flexible, but I did crack a little bit of his bondo... LOL

 

TTT...Still looking for a tank sending unit. I would like to find one to send and have rebuilt. Don't want the car on the lift for a extended period of time so want one ready to install. Thanks Steve

 

Did you send Tri Starr a picture of what you have left of your original? He may have enough parts to put one together for you.

 

I am hoping to find a good rebuildable one to send out for repair so I don't have the car apart on my lift for a extended period. Thank You Steve

 

Do you have the part number? If not, someone could post it. Once you have the number, search the internet for it and cross reference any interchange with Buicks and Pontiacs.

 

Check CT (CTC Auto Ranch) for the tank unit out of this Vista Cruiser:

I don't know the part number. Will check my parts book to see if it is listed. I will email ctc but the tank is not there unless it is stored somewhere. Steve

 

Bone yards often remove, drain and store the tanks first thing.

 

I will contact them. Thanks Steve

 

Steve—if the Olds unit does not work out, ask them about a Buick Estate wagon tank unit.

 

I notice that CT Auto also has a 70 Safari wagon. I would investigate whether the Pontiac wagon's sending unit will interchange with your Olds.

 

They did not have the tank or sending unit for the vista. Still trying to figure out part number and interchange. Steve

 

Searching and placing a parts wanted ad on this station wagon forum is another option:

Thank You. Steve

Thank you. Steve

 

Grp. 3.107---6428036, 1968-70 exc A/C...6428004, 1968-70 W/AC wagons of course.

 

A Buick Sport Wagon without AC 68-70 is also 6428036. Nether a Buick Sport wagon with Ac or a 70 Buick Estate wagon are the same as the Olds numbers posted above.

Thank You for the information. Steve

 

Thank You for the information. Steve

 

!969-70 Pontiac Safari wagons match 6428004:

Thank You that would widen the search parameters. Steve

 

Did the 70 Catalina wagon at DVAP not have this part?

 

Did not have that part, Steve

 

Still in need of this. I have contacted some yards without luck. If anyone has one working or not that would work. I can send it out for rebuild Thanks Steve

 

Did you check to see if this one has a donor?

I may have called already but worth trying again. Thank You
