George at Utterpower.com has some MICO filter housings for a good price. The are well built and don't leak. My Metro filter had a nice coiled cotton felt tube filter, but the housing leaked as badly as the rest of the fuel system so I changed to one of the Mico units, and am happy with it.
Watch out for you brass petcock on the tank- you might as well assume it will leak. NAPA has decent replacements with standard NPT threads.
Don't assume that your head clearance, injector timing, etc. are properly set as shipped. Glad your "kit" of assembled parts wasn't a sand hog.
