I mounted my fuel pump/pre-filter to the front side of the passenger footwell with these.
And mounted my Malpassi Filter King filter/regulator with SS cable clamps on the torsion tube on the inboard of the passenger side frame rail.
If I had to do it all over again, I’d keep the fuel pump on the beam but use SS cable clamps instead of putting it on the footwell, only because it hums a bit (cause it doesn’t know the words) and the footwell kind of amplifies it. OTOH, it’s comforting to hear it run before I start the engine. It’s inaudible with the engine running.
FWIW-CAP Hardware sells these rubber covered Stainless Steel cable clamps in just about every size. IMO, they’re one of the handiest things around for building our clown cars.
