66 Fuel Tank Interchange With Chevrolet?
Permalink  

There has been some discussion on here in the past regarding fuel tank interchange between 65-66 Canadian Pontiac and 65-66 Chevrolet. My memory says it's never been proven they interchange, and searching old threads on this site, I can't prove it either.

So, the million dollar question. Has anyone taken a tank from a 65-66 Chevrolet and installed it on a Canadian Pontiac, or the other way around?

We can speculate all we want knowing the frames are the same, but will it actually interchange?

Interesting, after I posted this, I decided to look up a tank at Spectra Premium Industries, a Canadian fuel tank company. I did this because I figured they should know a Canadian Pontiac from an American Pontiac.

Their site lists a GM37K 82 litre for Parisienne, GM37C 76 litre for Impala. Interesting, considering they show the length, width, height as being identical on both!

Tin Man, (Dave), if you see this, do you happen to have tanks from both of them off the cars that you can compare?

Hi Carl, all I can say is the rear cross member of the frame is different between Chev and Cdn Pontiac, I had to change it when i put the Cdn Pontiac frame under my 65. The donor didn't have a gas tank but by the looks of the cross member I would say the neck of the tank comes out slightly different. Chevy above, Pontiac maybe below? With a slight tweek to the neck it might work? Sorry don't have a spare Chevy tank to look at, but can take measurements/pictures of the one in my 65 if that helps.

 

Oh and we are talking fullsize here right? not Beaumont /Chevelle? wink

Yes, full size Dan.

I've been looking at pictures online. On Spectra's site, I think I can see the difference. The neck on the Chev tilts up, the neck on the Pontiac comes out pointing up but then has a kink to make it almost horizontal. The rest of the tank looks the same.

I am going to do some shopping online. I am sure I can change the neck from my old tank if need be.

I just sent an email to NOS to see if they carry a tank for a Canadian Poncho.

Thanks for the info, it pretty much assures me what I see in the pictures is correct then.

Yes I know you are talking fullsize.

That was a jab at why you posted this in the Beaumont section. A little sleepy when you started this post? wink still a little sleepy now? biggrin

Hi Carl

I did a replacement of gas tank with what I thought was a Pontiac tank. It turned out that it was a Chevy tank. The difference was that the Chevy tanks neck was in a more upward position and would not line up with the space in the bumper. I had to cut the neck off of my out tank and weld it so as to make it line up. The tank itself is the same just the neck isn't correct without the modification.

Perfect, thanks! That is what I suspected from looking at pictures online.

I have the correct one on order (hopefully) that is from Spectra, a Canadian company. I hope they know the difference between US and Canadian Pontiacs!

also 65 may need a "0 to 30 ohm" sender while a 66 needs a "0 to 90 ohm" sender

Looks right to me. Just be sure to be careful when you are taking the tank out of the box. They seem to have some very sharp edges. Cut the daylights out of three fingers.

good luck Carl

Good point Luppy. I noticed the edges on my used tank today. I was wearing gloves to handle it though.

I don't know how a 67 would factor against a 66 Carl, but I bought a new Spectra Premium for my GP. It was ordered as 67 Impala. I pulled the original tank and sat it facing "Tube to Tube" with the new one.

Sure enough, the new tank filler end was about 3" too low compared to the original GP tank. Same shape and length of the neck though. About 8" long if I remember. I was miffed.

Wanting the job done, I stood on the new tank where the filler entered and gently eased up a little at a time on the filler neck. It pulled up easily, and eventually I had a perfect match! The tank conformed no issue where the neck was soldered into it.

These tanks are made from a low carbon, Drawing Quality Galvanized steel, are soft, and will move and conform just a little at the neck entry no issue.

Perfect match would be best, but does anyone really make a tank for a 66 Parisienne???

Yes, actually Spectra lists one. The picture looks perfect compared to my orginal too, and when I look at the Impala tank picture, it is certainly different.

I'm gonna look now at Spectra's site. I thought they had for 67's also, but not certain on that.

Nope, 66 Parisienne listed, but not 67. Guess I'm just special, or something!

And for the record, I think I've mentioned this before but it's worth a reminder. The fuel tank strainer for the sending unit is still available from GM for all these older cars (for the 3/8" line at least, 327, 396,427's used 3/8"). 5651702 will get you a new strainer for about 19 bucks list price.

The 5/16 for the 6 cyl and 283 cars may be too, I never checked it.

On my 66 Grande Parisienne, the Spectra GM37K was a perfect fit with the perfect shape of filler neck. In the pictures, the filler neck for the Chevrolet was quite a bit different and looked like it would not allow the fuel nozzle to fit in unless the neck was bent. I think the tank itself without the neck is exactly the same between the two tanks.

Canadian Chev & Pontiacs  share the same chassis and driveline. The tanks are the same as well.
