1972 Polly gas tank swap...any fab work needed

[72freak]

I am needing to change out my stock 1972 Suburban gas tank because it is leaking. The polly tanks are cheaper than the steel replacements but I have heard that the fitting (hose) sizes and filler neck tube port are a different size from the original and require some step down hoses. Anyone know? Any truth to it?

Thanks

The neck is a little smaller, but I was able to just clamp the hose down enough to make a good seal. Otherwise it's a direct replacement.

They are 1 1/4" o.d. filler necks which are the same as my 67, 68, 69 Panel Trucks, and both my 68 & 71 Suburban have the same 1 1/4" stock necks. To my knowledge 72 are the same, the vent lines were all correct also on these.

I just put one in my 72 Suburban the only problem I ran into was the neck on the poly tank was not as long as the steel tank and I had to go to NAPA and get a longer piece of rubber gas fill hose. And hold on that hose is not cheap.

where did your tank come from?

The tanks are oversized so it would cost $15.80 for delivery, are poly tank by itself runs $149.95+15.80shipping=165.75 delivered to your door. You'll find them on the following page of our web site
