70 Chevelle, 489 BB, Jerico DR4
That's a pricey piece😁 Carter says 8 psi though. I'm not sure how legit some of these specs are.I ran the Carter M4889 for a while on my 540 and it put out a steady 7 psi. It wasn't enough for my motor so I upgraded it to the Carter M7901G pump which is their Billet aluminum pump and it fits the bill for my combo. The M7901G puts out 6 PSI. It's fed from 1/2'' stainless hard line and pick up from the tank to the pump, and 1/2'' stainless from the pump to both inlets on the carburetor. Its pricey, but its a great pump. Everyone hates it because it's anodized blue. I could care less, as long as it works.
