426 Hemi/440 Rod for Fuel Pump

[Thomas Schwartz]

HI All,

I'm having an issue with my 66 hemi not getting fuel.

Can anyone measure there Fuel Rod that goes in the block between the cam and the fuel pump arm? I need the thickness and the length. I'm told a 440 has the same length one as well.

Does anyone have one they can measure for me?

I don't have one to measure, but the 361, 383, 400, 413, 426W, Hemi, and 440 all use the same fuel pump rod, fyi

todays oil causes issues with that rod and cam .

Any chance ethanol could have ruined the check balls or seats in your fuel pump? You can pull the pump put it in a vice and actuate it by and with a suction hose in any liquid to check operation. It ain't broke till you can't fix it no more!

Good suggestion. I live in the Nazi run state of California. Weather great. Politics suck! I always use 91, which is the best pump gas available. But yes, they add the crap to it. I will do your test and see what I find. I already put a new pump on the car. So more stuff to check... But at least when I pour gas directly down the carb, it does run.

PS. Love the 65. One of my favorite years....

Remove fuel pump, remove plug and take rod out and examine for wear. Beware of some new ones being sold, apparently they wear premature. Originals work better, but maybe the parts guys fixed it with newer ones.

If you replaced pump, did you replace vapor separator?

Remove a fuel line and put a tube to a container and crank engine. If fuel is not moving, back to pump, lines, tank, etc... or did you get the lever on the plunger? You need to press the plunger up with some grease on it to hold in place. Cam needs to be in a retracted position, otherwise fuel lever goes over it and doesn't pump.

If it does pump, chances are you have a carb issue. Stuck check valve for accelerator pump, or float issue.

Rod should be 3.22" long.
