IH 91 Combine fuel pump

[Matt1983]

Hi everyone,
I'm still running an IH 91 combine to harvest rye. Its been a great machine for the 15 acres or so that we keep each year for reseeding cover crops. Last year the fuel pump went bad and I hooked up and electric unit to fix it but Id rather put an original mechanical pump back on. Does anyone know what pump was used on this? Most tractors of that era were gravity fed so I am having trouble crossing it over to any of the more common tractor engines.
Also as a side note, I need a new upper radiator hose. I haven't even begun looking for a new one so for all I know it may be very common but it doesn't hurt to ask if anyone knows the number that I should be looking for. Its a weird shape with a dramatic taper between the engine and the radiator.
Any help would be appreciated.
Thanks!

It is probably an A-C. My 151 and 141 have the glass bowl integral with the pump, like the Farmall F-series. If yours fits this description, repair kits can be had from Rice Equipment, Clarion, PA. for 75.00 This pump was also used by Le/Roi, Waukesha, and being a division of GM, I imagine some GMCs.

It's been a while since I've seen one, but agree with Fritz's comment that AC likely supplied the mechanical pump to IH. Try Dwayne Hansford at Rustic Red Acres, he handles some fuel pump parts.

I'm pretty sure IH either equipped the later 91 combines with an electric pump, and/or, there was a conversion package to put an electric pump on these combines.

Also as a side note, I need a new upper radiator hose. I haven't even begun looking for a new one so for all I know it may be very common but it doesn't hurt to ask if anyone knows the number that I should be looking for. Its a weird shape with a dramatic taper between the engine and the radiator.

I think (can double check parts book in a day or two) that the top radiator hose is the same as the 340 gas tractor. If so, the hose should be available, but pricey.

We had a 91 and 93, both Beaners and both came thru my gramps' dealership, and both had electric pumps. He taught me to listen to the pump after turning on the switch, which you could clearly hear from the platform in the morning, and when it quit pulsing, the carb was full and ready to start. 93 had a little more power, and IIRC the gas tank was slightly larger. 93 bin was larger, but they made a bolt-on extension for the top of the 91 bin, which ours had
