There has been lots of interest in EFI recently. I'm using a Tanks, Inc #U9-A trunk mounted tank, and all that is needed to convert it for EFI service is a return port. The easy way to do that is to either 1) weld a NPT bung on the blankoff plate for the filler port not used, either top or end, or 2) (my way) drill a nominal 9/16" hole in the blankoff and install a bulkhead AN to barbed hose fitting, with a short piece of hose inside the tank to direct flow down into the tank volume. I'm using the top port for a straight neck, billet cap filler port, leaving the end port for the return line. I can zip tie the internal return hose to the internal supply tube, then install the blankoff plate with gasket. Tanks, Inc says that the solution to EFI is their internal tank mounted pump assembly, with the supply, return, and vent on one bolt on connection, but all you need is a return port to make the universal tank work. For me, I like an external, frame mounted pump for future troubleshooting/maintenance access. Here is the #U9-A tank I'm using. One thing to know, the slanted filler is only available for external connection, no cap. The billet cap only comes on the straight neck filler. My tank tilts back about 12 degrees to hook to the internal steel bracing, so a straight neck will be OK.
