Yeah, the measurements are in the Jegs catalog. I was going to go buy it tomorrow (actually, later today since it's so late, err early).
Yes I'm using hard line, though I suppose I could use steel braided with some AN to NPT and vice-versa fittings.
I'd planned on mounting it in the engine compartment so it could be between the pump and carb. After looking over the engine compartment a second time, I figured I could just use a male-to-male pipe nipple from the pump to the filter instead of a small section of hard line like I mentioned in my original post. That could act as a partial mounting bracket (I would also bend something up to reinforce it more, as well). The tricky part would be getting the filter to line up in the correct vertical position when everything tightens up. I figure I could just wrap the threads with some teflon tape so that it tightens where I need it to be.
