Here is what I did. I went to the local hydraulic hose place with my buddy that specializes in HD machinery. We looked at the closest fittings in diameter, cut one end off, drilled it out a bit....then allowed a SOLID welding base. My fittings are steel not alum. I think you can do it with alum fittings but would need to find a local welding house that can silver solder. Hell of an opportunity for a company to make these without the pumps and AN fittings premade. I like the idea of buying a 500-700$ sending unit and pump, but my pocket book says otherwise right now.
