John,
I filled it with acetone, pressurized it to ~60psi. Found 2 pin hole leaks, welded up the leaks and called it good. It shouldn't see more than ~4 psi while in use, so I think it should be good.....
Mike,
I plan to bolt it to the front side of the fuel cell box, just rear of the mustache bar. I have just over 4" of clearance there.
qwik240z,
MSA has some nice ones in their latest catalogue for ~$40, but will need some modification for more inlet/outlets, depending on your application.
I made mine up fairly quickly and cheaply, and it will be hidden under the car, so the bling bling factor doesn't come into play.....
