Anyone have a fuel pump push rod break in half?

[sschaefer3]

I did, looks like a cast part and it broke right in the middle. I'll post photos in the AM but is seems weird that a shaft in a bore would literally break in half. 80K miles. GM still had new ones available.

I've seen that mentioned on here before, and I've heard of it from other sources. Doesn't seem to be common, but it happens.

The only thing I can think of is some sort of vibration would cause that. Maybe some slop between the pump arm and the shaft? Or slop in the shaft bore? And ,or ah bent shaft, I've seen that happen during improper installation of the pump. Don't ask how I know that.

Looks like it's time for an electric fuel pump.

We bought a new rod from GM it was only $25.08 retail, which is what the shop charged me. GM 14050425

My truck is all fixed with a new AC Delco pump and new rod, but Thanks!

I had a 1984 K10 with a 305 in it and I broke mechanical fuel pumps left and right. I finally put in a electric pump but had problems with that, I thought. That was later tracked down to a distributor issue. The issue with the mechanical pumps was that the push rod itself was the problem. That was found out when it broke in half. Apparently the failing rod had been beating the pump arms to death. Replaced the rod and never had another issue with the pump.

Can you install an electric pump on a Hmmwv? I just had my fuel pump rod break off on the top end and is now stuck in the block.
