Let me ask you guys out here how many of you are running a mechanical fuel pump that puts out high pressure that is above 7 PSI well above and did you run a hardened steel fuel pin push rod with the setup..
If you have or you did in the past let me know plus if any of you might have one for sale not a factory one I'm talking about one of the hardened steel fuel pin pushrods better made by comp or that hughes engine sells..
 
After this Howard's hardened push rod left me on the side of the road I will not trust any aftermarket push rod. I bought 5 NOS factory units for future use.

The hardened steel rod is for stock type iron cams. Is that what you have or a roller cam?
 
Still running the OE rod that came in my Bee in 1969... 156,000+ miles.... 45,000 or so since rebuild in 1978 reusing the original rod! Still pumping gas.
 
I got 112k out of my original and it quit. Put in a near perfect full length used original. That should last til i'm a pile of dust in the ground.

No I'm running the Mopar performance 312 590 cam shaft but what I'm running for my mechanical fuel pump is a clay Smith high-volume fuel pump pan the arm on it is I guess very hardened steel it's not your stock placement fuel pump for a me like this this thing puts out 130 140 gallons per hour I was told but I want to run a hardened steel tip fuel pin push rod because of the fuel pumps arm material
 
Got any heat treatment shops near by? Take one there they'll harden up, don't drop it'll shatter. They can induction harden the ends.

Kidding.:D

I would imagine the end of the rod that rides on the cam eccentric will be exposed to considerably more wear than the pump arm end. Wouldn't see why you couldn't use the oem steel version. Comp has the replacement with heat treated tips for around $30.

Think the pump design has more to do with psi and volume than anything else. If Lee Smith thought they needed a special think they'd make/supply one.
