What kind of Fuel Pressure will 20XE with Twin 45 Dellorto's need? got a Facet Red top fuel pump atm but i think their soo ugly and quite large so nowhere to hide it out of bay, was thinking of fitting the newer type Facet Posi-Flow which are pretty small, but available in different pressures. ime still going to run an inline FPR whihc has been set by Bog Brothers last time it was tuned. Any help would be appreciated.
