Hi Guys! I'm sorry for not getting back here over the last 36 hours or so. Life got in the way. Yes, it is a carburetor on a 454. Have not eye-balled the electric pump yet, but I suspect it's behind a cover where fuel hoses are leading just behind the outer passenger wall behind the rear wheels, opposite the regulator mount adjacent to the fuel tank.
In any event, I removed it yesterday. Although it is possible that it just needed cleaning, I made a decision to get a new one. I'll keep the old one and see about cleaning, or maybe seeing if a kit is still available.
In the meantime, right or wrong, I ordered a Holley 12-803. This model is for a carbureated motor. By purchasing it thru Amazon online, I was able to receive it overnight. Got it delivered as I'm writing this.
It has a range of 4.5-9 psi. Just for reference, I put a call in to Holley and they indicated that I need about 5-6 psi for my particular motor/carb. Holley indicated that the regulator should be fine for that without adjustment.
I will install it within the next few days and report back.
Thanks for the replies.
