Moroso EFI fuel return line kits will allow you to convert to fuel injection without welding a return line or fitting into the gas tank. Just cut a 2.75 in. section out of any 2 in. fuel tank filler tube neck, and insert the billet aluminum adapter. Use the included Buna-N sleeves and four stainless steel hose clamps to seal the connection on each end of the adapter. They include a 3/8 in. aluminum fitting with a smooth 90 degree bend to direct fuel downward into the tank.
