I want to modify my dual aluminum fuel tank(s) on my cabover to allow me to run in-tank fuel pumps for Throttle body Fuel Injection on my 406 SBC. I have some Questions. 1. Is there an inexpensive way to mount pumps into the tanks? 2. Who supplies various flanges that I can weld onto the tank and use to mount the pumps? 3. How do I isolate the tank from the steel mounting surface? 4. Can I drill and tap the 1/8" aluminum so that it will hold a bolt on flange? (is it thick enough) 5. Does anyone sell a weld in flange to use factory GM style pump pickups with the twist ring? 6. How big should the internal tray be...and how big for the drain/fill hole on the end? Any other advice anyone can offer? Thanks in advance.
