Im running a Holley blue pump and holley reg which is adjusted to 5psi (wot) but occasionly the pressure seems to spike to 9 thus causing it to push past the floats and actually over flow over the top of the carb :eek:

both the pump and reg were new when fitted but im wondering whether to replace with a supply and demand electric pump or go for a std chevy mech pump or even just replace the regulator :?:

Ant idea's or reconmendation's :tup:

(need it to have 10mm tails for fuel hose)

Sounds like your reg is fooked, strip it and have a look to see if there is anything immediately wrong. If it's overflowing by that much then you stand a chance of hydraulically locking your motor anf wrecking it :-(
