Back in the fall Holley introduced a new product at the SEMA show, the Holley Hydramat. It's a product that mounts in the bottom of a fuel tank and if the fuel in the tank touches any part of the Hydramat the fuel will be sucked in even if no gas is touching the rest of the hydramat.

Holley started shipping about a month ago so I ordered one and got it a couple weeks ago so I thought I'd show it here. Will post about it again when I get it set up in the tank. Cost of mine was a couple hundred bucks. Seems expensive but to save the same weight (on track) with lightweight parts would cost more
This looked like a good product for me to try in my stock unbaffled gas tank until I can install a properly mounted and protected fuel cell. It'll allow me to save weight by keeping less fuel in the car on road courses without risking sucking air in high G corners, reduce the pendulum effect of fuel sloshing in the tank, be safer if there's a fire because less fuel in the car, and since it's also a filter I eliminate the canister fuel filter I've been using also saving weight.
I got the magnet kit for mounting the mat in the tank and will need to install submersible fuel line instead of the stock tube and sock strainer in the tank. Holley makes other sizes and shapes of the mat as well as types of mounting setups for tanks made out of other materials.
