The above link sells the Webb VorMax filter for $250. I was going to copy/paste info from their web site but they do not allow this. Viewing the source code of their web side one finds this nice little copyright notice:

I guess I'm in violation of their copyright notice since I copied it from their web side.
Anyway, they comment that due to it's large size and large inlet and outlet ports, the Webb VorMax may not be the best filter option for everyone. They only recommend its use on trucks with heavily modified fuel systems with larger fuel pump and feed lines.
There, I only used part of their words.
