Been having fuel problems for 3 years. New fuel tank, fuel line, 3 different fuel pumps, 3 different carbs and new pick up/sending unit. One thing I never thought to replace was the fuel pump push rod  :brickwall:

Ordered a new Carter fuel pump and Comp Cams fuel rod and put them both in yesterday...Here's what I found.







Long Story short car runs great now  :brickwall: :slap:

The issue wouldn't be hesitation would it?  If so I know what I have to do with my Coronet....

Ran into lots of these , a few years back I was at a show & a guy had a 69 Charger , he had a new engine in the car & had gone through what youdid had it into numerous shops , finally called me , carb wouldn't stay full , popped the fuel pump off , same problem , years of frustration & lots of $$ , the machine shop never even pulled the rod when they rebuilt it :brickwall:

Same thing here, my engine was rebuilt in December 2008 and the guy who rebuilt it never even checked it or put a new one in.

As for signs of problem, My car would fire up and run great one day, next day would be bogging out and running like shit. Finally in Feb I was driving only a couple miles from home at about 40mph and the car just died. Coasted to a stop and tried cranking it, nothing. Popped air cleaner off and looked in sight glass of my aluminum 770 Holley Street Avenger carb, bone dry. Sprayed a little carb cleaner in front bowl and fired right up but wouldn't stay running if I didn't spray. Got promoted at work and was busy and sidetracked with other projects from Feb until this past weekend. Drove the car Sat night after finishing it and also just drove it to my parents and back tonight, runs great.

I was so tired of messing with this thing. Put on a new Year One tank thinking my old one had dirt and shit in it, Put on 3 different Napa Gold fuel pumps, New metal line from pump to carb as well as new rubber line off inlet of fuel pump. Also put on 3 different carbs. Edelbrock 750, sent my original Carter 4401 i believe to be restored/rebuilt, and now my new Aluminum Holley 770 Street Avenger......All for a $22 fuel pump push rod LOL.

Oh well at least everything is new now, also I really like the performance of my new street avenger carb, great throttle response and performance over the stock 625cfm Carter.

Thanks for the help with parts recommendations guys I appreciate it :2thumbs:

There is good reason why I recommend Holley or Proform over other carbs , they simply work a lot better .
Glad you got it narrowed down ....g o enjoy the car this summer  :2thumbs:

I've had a fuel issue with my Coronet since I bought her 8 years ago.  This is why I'm asking questions on this thread because this is the one thing I haven't replaced.   I went through a bunch of hoops like the OP, and hope this solves my issue. :2thumbs:

Yeah for sure, Let me know if you need any help or have any questions. I'm sure there are other companies that make the fuel pump push rod but I just called Comp Cams because I am running one of their cams and wanted to make sure I got the correct one, They recommended Comp Cams #4626 I'm sure it will fit your car, Was about $22-23

So what is the correct length for the fuel pump push rod?

I believe it's supposed to be 3.25".

Can anyone post up a pic of this rod in situ?? does it just sit behind the pump or something??

Just curious

Cheers  :cheers:

A383Wing

yes, sits in a hole that goes up about 45* from the pump lever...you have to remove the pipe plug under the pump to get it out...then use some wheel bearing grease to install so it stays in place while installing pump. To many times I have heard of people putting new fuel pumps in an the rod fell from the cam and the lever was on the side of the rod instead of under it.

Pics should be in the service manual

I'm not a very good mechanic and I managed it lol...Just like these guys said I took some grease out of my grease gun and spread a light layer on and slid it up in there...After that I used a flashlight with one hand and the fuel pump in the other hand and shined the light in there from the side to watch and make sure I slid the pump underneath the rod then put the pump flush with the block and bolted it up...also make sure your gasket doesn't move mine slid down a little so I had to make sure it was lined up correctly with the pump.
