Whenever my fuel tank gets down to 1/2 and below, I can easily hear (and feel) fuel sloshing around when I stop or turn corners. Does anyone make an internally baffled fuel tank for A bodies?

Sorry, that's part of the A-body experience (along with saggy rear springs). THe project wouldn't be too hard to make or build one, if you have a couple of good clean cores to work with, and are handy with a tig welder...


Time to get 'buddies' with my brother the welder, when the 'off season' starts and see what he thinks...

It'd definitely be a great project to work on. Be very beneficial to avoiding starving the fuel pickup when doing a Steve McQueen around corners :P

The sock almost literally sits on the floor of the tank, you'd have to have about 1/2 gallon of gas before starving the pickup. Where it staves out is the float in your carb (if still running a Holley 1945, this is quite common, and actually was a known problem in the 1974 cars, along with the floats sinking).

I had the baffle system breakloose on an old T-bird once-upon-a-time....

Anyway, it consisted of a pan surrounding the fuel pump and fuel-pump pickup.

But here's the important part, fuel got into the pan from tubes that entered from one side of the pan on the outside, but exited on the other side of the pan on the inside, not just holes in the pan. This tended to trap fuel in the pan so the pickup wouldn't suck air when cornering

I had a gentleman suggest to me, that filling the tank with wiffel balls (the perforated plastic base-balls) would solve all the problems...

I didn't like the idea of loosing the sending unit.

True. A car that won't run because its engine is internally coated with whiffle balls melted by gasoline, won't tend to create any sloshing noises from the gas tank when going round corners.

Well that hasn't happened to me yet, but now that I have yet another reason to lose the POS 1945 and replace it with a Carter or 1920, I oughta put the money aside and get one so I can install it ASAP and not have it always fricken die in the cold weather.

Resulting in the owner being baffled, not the fuel tank.

Get the foam that's used in aftermarket fuel cells. It would be no problem to squeeze enough blocks of it thru the filler tube hole (the opening in the tank, not the tube) to prevent slosh.

foam? must be some sort of special stuff! isn't styrofoam what the crazy pyro kids melt into gasoline for home-made napalm?


also, wouldn't the foam displace a lot of the tanks volume? effectively reducing it's capacity?
