Hi Captain,
Welcome to Oldgas.com Shop Talk.

Making your own fuel is one thing, but making larger quantities and selling it brings in complications. You'll have to be certain to conform to fire, safety and environmental rules or you'll risk big problems with the law.

Check with a local member of PEI, Petroleum Equipment Institute at http://www.pei.org/
for help with fire, safety and environmental compliance.

Check with Ark Petroleum on the Web at
http://www.benfordfueling.com/
for which pump models will have available replacement functional parts.

Best of luck on using a vintage pump. Sounds like a cool idea.
