I'm installing a new gas tank in my 1949 3600. Ordered the new one from Jim Carter that advertises a more accurate angle to the inlet and vent pipes: https://www.oldchevytrucks.com/cart/product.asp?prodid=MEG150&i=19888|||||
Of course, once in hand, they don't line up so well with the existing filler/vent tube. If the filler lines up then the vent is off center to its pipe by 3/4", and the filler tube while it is aligned with its tank tube is doing so at a different angle (off by about 3 degrees). Probably nothing that can't be fixed with the short length of rubber hoses, but the old tank lined up perfectly (and sadly it is one rusty barnacle!).
Is there something I'm missing? Or any tips/tricks? Otherwise I'm bolting this thing down tomorrow and hoping for no fumes in the cockpit!
Can't say. I got one from Rock Auto maybe 3 or 4 years ago for $110 plus shipping and you couldn't have had a more accurate lineup for the filler, vent and lower outlet. The tank was made in Canada and I think the name of the company was Spectrum, Spectra or something like that. I was very impressed with the way it was built and packed. I did have to work a bit on the rubber cab grommet, but you want that to be a tight fit.
I put in a new filler grommet, tight but no big deal. And I've rotated the filler pipe every different way but no joy. I'm using the original filler pipe, I wonder if the reproduction fillers are different?
Ed, from your pic it looks like you have the tank tipping backwards about 3 degrees? Is that just the pic or did you deliberately not mount it upright?
The tank I got came with a sheet of self-adhesive 1/16" thick neoprene which you could cut as needed (according to the instruction sheet that came in the box). Very impressive product and less costly than many of the other options out there. If your outside rubber grommet doesn't seal quite right, use some 3M 08509 Auto Bedding and Glazing Compound. It stays flexible until a week after forever.
Ed, yep, a little tilt back is the only way it would mount. Odd because that creates a small pooling area in the back edge of the tank. I originally fiddled with the location of the tank until the filler and vent pipes lined up (better but still not perfect), but then the outlet under the tank wouldn't match up with the hole in the floor.
