View Full Version : Chris Craft 350Q fuel system

I am trying to get her run right for the summer.
I have found one of the Carter fuel pumps is not pulling her weight.
Where can I find a rebuild kit?"

Better replace it with a new one. About 60 bucks.

Robert will have the rebuild kit."

The original pumps are years out of production.
There doesn't seem to be any next best model to replace it.
But Robert at chris-craft-parts will be supplying the rebuild kits.
I will post the results when it's done.

What was your symptom I have 1 350Q that will not run above 3400 to 3600 RPM the other tops at 4200 as it should. I am wondering if it is starving for fuel? Considering the fuel pump too?

"the symptoms I started with, like you engines don't follow.
The chase and the fix.
The bad gas, get it out.
Fuel filters full of cra_. Sub in a large volume filter before engine filters.check and replace in-line filters as required.
Pull the carbs and have them remanufactured.
The total of the problems and the fixes.
every fix helped to some degree. I replaced the plugs several times for fouling and the plug wires after I got tired of replacing the plugs.
I will have the carbs back in a few days, and hope to be able to balance the drives under load.
will post again when I have the carbs installed"
You can buy a new Carter AV4891 (Marine)pump and take the old pump arm off your old pump. Then replace the arm on the new pump with the old one. This way you have a new pump and it takes a lot less time and effort to do. I have one on my 350 Catalina with 350Qs and it works fine. You can get the pump at DirtTracker.com or Summitracing.com. Summit's is a little cheaper
