So, swapped out a fuel pump on what I think is a 1982 250 I6. From what I researched it was going to have a rod mated up to the crank but what found was a crank style assembly. (No rod) am I looking at a 250 from 1982 or something different. Or is my rod missing , stuck, fell out and I couldn’t find it. Im a novice at this just want my old truck to run again started with fuel pump
And lines. Thanks for the help.
I have a '68 250ci I6, and I just recently replaced my feul pump. This type of engine does not have a feul pump push rod, the arm of the feul pump rides directly on the camshaft lobe. I believe all the chevy straight 6s of this generation are the same. If you bought a replacement pump for a chevy 250, it should be fine. You should be able to reach your finger in the hole in the block, and feel the cam shaft and the lobe, as it shows in your diagram. Your diagram is exactly accurate to what you have in your engine.
If its the right pump, it should have an arm long enough to reach that, and I believe it will have a small plate of a different grade metal attached to the end that rides on the cam.
On a Chevy V8, small block or big block, up to about 1986ish, they have a pushrod that rode the lobe on the cam, and the pushrod is what ran the fuel pump, that's probably what your thinking of.
But no pushrod in a straight six.
