Why different levers?

[Fernando Mendes]

230 and 251 engines have the same camshaft,no?Then why they have different fuel pump levers angle?My engine is an IND-251.

The 230 is 23 inches long, the 251 is 25 inches long. Doubt the cams are the same.

From what I recall my 218 25" block too the same as the 251 shown above, but it was well over $200 here from the parts store, so I went to an electric fuel pump...took a few years to find one that will last awhile, but fingers crossed on my purolator pump.

Ok,but I referred to the different lever angles.

Why is the diaphragm assembly to the top on one, and on the bottom of the other?  Maybe to accommodate the different levers!

My 251 runs with that pump since 1987,with me.

One can pushes the rod, the other lifts...your 251 lifts...the lobe will be different then the 230

Both levers work on both 23 and 25" engines. One goes on top of the cam the other on the side.

My 251 CARTER fuel pump was still without sufficient stroke to send gasoline to the carburetor.The engine starts and stop to function.I spent 2(two) months to know my problem was still my pump without sufficient stroke.Today I put a thick rubber gasket between the two parts of the pump to INCREASE the stroke.See pics.

On my last fuel pump the mounting gasket, the one to the block would reduce the pump pressure. I had to remove the gasket, and just used rtv sealer and it worked great. The thickness of the gasket was enough to stop a good pump.      I bolted it on, without any sealer or gasket and started the truck and it ran great. Pulled it off, cleaned everything, used a very thin layer of the rtv bolted it on.

Thanks for your input.A friend spoke this same to me.I can try your experiment.
