Mr Pagel has stated before that altering a OEM tank is a no-no and that includes putting a hydromat in an OEM tank.

Re: Holley Mat

Hydramats have an integrated female 3/8" NPT fitting. Getting from there to a generic metal pickup tube (that's either for a fuel cell or for a stock-type application that will never race in Lemons) is just a matter of plumbing. I highly recommend the fancy anodized push-lock fittings and fuel-submersible hose recommended for proper fuel cell applications. I used a site called ANPlumbing.com when we did a fuel cell in the Dart; they had stuff from many different manufacturers all sorted into nice categories for easy price comparison.

Theoretically, getting to a stock-type metal pickup tube on a street car would be best done with a flare fitting, but if you can't flare the tube then a properly-installed compression fitting would work.

Re: Holley Mat

I guess I didn't really see where a mat inside of the gas tank would be any kind of safety issue? It seems to me as a larger filter or sock as they say. What is the safety issue? I'm curious.

Re: Holley Mat

I think it depends on the tank. To put a mat in some would require getting a bunch of baffling out of the tank. Baffling that may not only be preventing slosh and starvation, but may be vapor isolation to prevent a fire.

Re: Holley Mat

I've done this with a '73 Suburban tank. Pretty easy.

In fact they have a sample how to in the Holley install PDF: https://documents.holley.com/199r10782rev7.pdf

Page 6 is the method I used.... not on a Lemons car. In an un-baffled '73 tank...
