well my previous EFi setup is still intact. The EFi pump Was wired up with a relay so that it 'primed' on accesory and then ran on start.

Crazily enough the Holley TBi doesn't run on normal EFi pressure (45psi) it runs on 15psi.. and the carb runs on 4-5psi lol.

So I'll have to swap to this pump I have at the moment whilst on the carb which is 30MPG and 4-9psi... and then probably get a holley blue or something later for the throttleinj.
