I am converting my 74 2.0 to dell 40s. How do I plumb the fuel. Is there a fuel scavenge. My " new " fuel pump only has an in and out. My old one for the fi has three lines. If I dont need a scavenge or return why does one carb have two hose fittings at the banjo fitting?
ANY help is greatfully welcomed.
Thanks
Shane
