Currently running a holley 750 double pumper with vac secondary's and while out hotrodding around and jumping I noticed that the current holley Mighty mite 34gph 7-10 psi electric fuel pump cannot keep the carb full of fuel when at wide open throttle.
From day one the holley mighty might has barely been able to maintain 4 psi at the carb.
Anyone have any ideas?
I was thinking perhaps a Holley Blue 110gph 7psi pump and regulator part# 12-802-1
1986 Suburban
454 big block
speed demon air gap intake
Engine pro MC2004 hydraulic flat tappet stage 2 cam with roller rockers.
Heads are the old scool 290's with mild porting.
Manual transmission
