I’m trying to find a gas tank with a filler neck for my 67 Skylark. For some reason every tank I find for the 67 has no neck filler. On Jegs I found one for 64-66 and Pretty much looks identical. The only difference I found is that it is 1.5 gal bigger? Any ideas guys? Thanks
If your tank has only 1 vent towards the front of the car use this one..............https://www.autocityclassic.com/196...buick/oldsmobile-a-body-zinc-gas-tank-gm37jq/ If it has 2 vents towards the rear use this one...................................................https://www.autocityclassic.com/196...1967-oldsmobile-zinc-gas-tank-2-vents-gm37gq/ Both types also come in stainless if desired.
Nice! thank you for the reply. My tank has two vents at the rear but they were looped together by a rubber hose. Not sure what the purpose of that was. I bought the car for my friend and I don’t know what all he did to it. Shouldn’t one of those be vented ? I was thinking about adding a check valve. Didn’t seem like the old tank set up had aNy ventilation.
This is straight from the service manual, which BTW you should pick up a copy for yourself................ 8 0 - 2 DESCRIPTION AND OPERATION FUEL TANK AND FUEL SYSTEM SECTION A FUEL TANK AND FUEL SYSTEM CONTENTS Division I n in Paragraph 80-1 80-2 Subject SPECIFICATIONS AND ADJUSTMENTS: DESCRIPTION AND OPERATION: Description of Fuel Tank and Fuel System SERVICE PROCEDURES: Removal of Gas Tank or Gas Gauge Tank Unit Page 80-2 80-3 DIVISION I I DESCRIPTION AND OPERATION 8 0 - 1 DESCRIPTION OF FUEL TANK AND FUEL SYSTEM In all m o d e l s except station wagons, the fuel tank is attached under the trunk floor pan by two straps and is of the center fill design. The filler neck extends from the rear upper center of the tank to a point just forward of the rear bumper. See Figure 80-1. To fill the tank, pull down the spring-loaded l i c e n s e p l a t e bracket and remove the filler cap. In station wagons, a longer filler neck extends to a door in the left rear quarter panel behind t h e rear wheel. See Figures 80-2 & 3. The filler in station wagons is made up of two sections joined by a short hose and clamps. To fill the tank, lift the spring-loaded filler door and remove the filler cap. Filler necks are soldered into the tank in all lower series cars. See Figure 80-1. In u p p e r series cars, the lower end of the filler slides through an O-ring seal and is held in position by a bracket and screw near the upper end. See Figure 80-4. In all models except station wag- ons, the tank is vented during operation by a special breather, rather than at the filler cap. (A "NO VENT" type filler cap is used.) In Specials and Skylarks, this breather consists of two pipes extending from the upper left rear corner of the tank; one pipe vents the left rear corner and the other pipe leads to the right front corner. Two rubber hoses are held in position verti- cally to prevent fuel loss from fuel sloshing. See Figure 80-1. With this arrangement of vents, the uppermost part of the tank is always vented, whether the car is sideways to a slope or straight with the slope. This prevents fuel loss due to expansion of trapped air. In L e S a b r e s , Wildcats and Electras, the breather functions the same as in Specials, but is located at the right front upper corner. See Figure 80-4. In Rivieras, this breather is an inverted U-shaped pipe extending upward from the right front cor- ner of the tank and is fastened to the body. See Figure 80-5. In Rivieras, this pipe provides the only venting both during opera- tion and during filling. In all models except Rivieras and station wagons, the tank is vented during filling by a baffle which extends from the lower end nearly to the upper end in the upper in- side of the filler. In station wagons, the tank is vented only at the filler cap. A special external vent pipe extends from the top of the tank to a point in the filler neck just under the cap. See Figures 80-2 & 3. The tank outlet consists of a com- bination fuel pick-up, filter and fuel gauge tank unit. The tank unit can be removed by removing a cam ring which retains the unit; in Specials and Skylarks, this can be accomplished without lowering the fuel tan
Cool. I’ll definitely pick one up. From what I can tell the two left vents are vented to the atmosphere. Maybe i could run two hoses to two small breathers or to check valves?
This is what I used on my car.............https://www.thepartsplaceinc.com/pr...urge-valve-replacement-for-gm-403846-ea/32744 I just added a short piece of hose to the top nipple when I installed mine.
As mentioned above the GM37G is the tank you need if you want tank for a ‘67 Buick A-body with a filler neck attached and 2 vents. Many places sell the GM37G with very different prices BUT the shipping cost will be dramatically different as well so be sure to look at the overall cost. For instance I just bought one these tanks back in July and Autocity classics wanted $65 for shipping. Amazon had the tank at a higher price but with their free shipping it was cheaper to buy from Amazon. Prices may have changed since July but just be aware that the shipping cost for a gas tank can be very high due to the large size. Also, make sure you are getting a Spectra tank. When I tried to buy one for my GTO the tank that two different vendors tried to sell me was a steel tank that was painted silver, not coated like a factory tank. So just be aware there are more than one supplier of tanks. Also consider a new set of gas tank straps if appearance is important to you. Here is a thread from 2018 about the same ‘67 gas tanks: https://www.v8buick.com/index.php?threads/67-gs400-repro-gas-tank.333294/#post-2800409 Here is how the tanks are shipped so it’s not uncommon to read about them arriving with damage. With my buick tank the filler only stuck out of the box a few inches but the GTO tank had the filler neck sticking out over a foot. I’ve been fortunate to not have a tank arrive damaged.
