I have a 1974 455 olds that needs a new carb. (quadrajet) and a new mechanical fuel pump. Anyone have either one for sale? Or maybe someone could point me in the direction of a good boat parts dealer. Yes, I'm a newbie, this is my first jet..... and I love it!

By the way I live in Firebaugh, California. Near Fresno

Fuel Pump - Auto parts store
Carb - Pick up a holley, they are plentiful on ebay and sometimes on here (What size do you need). Rebuild it and go.
Welcome to the site. We like pictures of boats around here...post 'em up!

pics to be coming soon, night time right now! Can you tell me why I should change to a holley. I am in no way doubting your opinion and I appreciate you taking the time to advise me, it's just that the guy I bought the boat from said it ran great with the rochester and I don't know enough about it to go against that. Also, I have been told not to get parts for my boat from the auto parts store because auto parts and marine parts aren't made the same. Like I said, I just dont know. Thanks for your help.

Oh yah, I have no idea what size I would need. How would I find that out? The engine is completly stock, never been rebuilt, spent most of its life in the garage. Bought from the original owner. It is a hardin marine and the valve covers say 455 olds 390 h.p.

Aftermarket parts like Holley, edelbrock, etc offer the ability to tune for your exact application and any changes you may make down the road. Also the rebuild kits for them are available at just about every auto parts store that may be near you. A parts failure is the perfect opportunity to upgrade to the aftermarket.
The fuel pump your looking for is probably the Marine one with the malfunction tube that runs to the carb, right? I dont know much about the Olds motor, wonder if its the same as the BBC? An after market fuel pump (Electrical and Mechanical) for the most part will allow you to run higher pressure/volume then the stock one.
Most of us are in the habit of adding more power, which in turn will require more air/fuel. Hence, an aftermarket carb and pump. I see no real reason to replace worn out parts (For the most part) with stock original ones.
just my .02

There should be some number/letter combination somewhere on it. Havent looked at a Rochester in almost 15 years since i swapped out the tired one on my El Camino for a Edelbrock 750cfm so I dont remember where, but when you find them google will tell you alot about the parts.
