Need some help! I'm running a 350 SBC with a 671 blower with dual 600 Edelbrocks. The blower is 20% under-driven. I came off the blower base plate to run vacuum to PVC and trans module. The hose to the trans module fills with raw fuel, not totally, but about a thimbles worth. I've got vacuum at the hose with engine running and hose off at modulator. Whats up with that???
