Holley Hydramat

Hello,
I just wanted to share my experience with the Hydramat so that it might help others. I bought Part # 16-101 which is a 15" by 8" X.
I needed a little more capacity in the tank because there were only 7 usable gallons before starvation in the stock 85 tank. This is under track conditions.
I found an 87 tank but it had pinholes and was very dirty inside. I didn't feel like I could properly clean and repair the tank with the stock baffle but did not want to risk getting less usable fuel so it sat for about a year. When the Hydramat came out I decided to risk removing the stock baffle and rely on the Hydramat to collect the last bit of fuel.
I turned down the flats on a "precision" NPT fitting to the same size as the stock fuel pump inlet and used a very short piece of fuel submersible hose to connect them. I also bought magnets from McMaster and attached them to the holes in the corners of the Hydramat to keep it on the floor of the tank. I had to cut the stock fuel feed on the sender back so that the fuel pump could sit higher. I also cut back the return so that it would sit above the Hydramat the required depth.
This setup works fantastic! The added capacity of the 87 tank helps, but the Hydramat is also better than a stock baffle. When fuel starvation would occur on the 85 tank then as many as 5 more laps and possibly more could be made. With the Hydramat barely 2 and the tank is absolutely dry.
This may not be the best solution for everyone's situation but it is was a miracle worker for me!
