I have been searching for a fuel filter that has a 5/16 inlet and a 3/8 outlet. The steel line from my fuel pump is 5/16 and the inlet for my edelbrock carb is 3/8. I currently have a cheap spectre glass filter that you can plumb with different sized inlets. It's ok, but I would rather run a higher quality filter. I was thinking about changing the carb inlet to 5/16 so I could just run any 5/16 in/out filter, but I can't seem to find a 5/16 inlet with the correct 5/8 in.-20 Male Thread. Any suggestions?

I cannot find anything that is 5/8-20, are you sure?
Not SAE, not JIC/ AN, not inverted flare, and not U.S. pipe threads
What I was going to suggest, let's say it's JIC/ AN O ring. Easy. Go to anyplace that sells hydraulic fittings, get a fitting that screws into the pump, cut it off if necessary, then drill / rheam/ thread it for 1/8 or 1/4 U.S. pipe, and then screw whatever size hose barb x pipe fitting you want into the adapter.

Here is the inlet on my carb. http://www.summitracing.com/parts/EDL-1497/ Am I reading it right? Thanks for the suggestion.

Ahhhhh for some reason I was thinking threads in the pump (as in "big electric") instead of the carb. Those are proprietary fittings. SOMEONE may make the one you seek, I just don't know who.
So I"m guessing the line from your pump is the mechanical pump. I've cheated in the past, some 5/16 hose you can stretch over 3/8, and some 3/8 hose you can clamp down on 5/16

Yeah, that's the way I had it before I bought the glass filter with the different in/out sizes. I'm just surprised no big name filter companies have made something like this.
Looked at their website. Looked like good stuff. I'll have to see if they have what im looking for.
