RE: [G104] fuel pump mystery
Kurt, You never cease to amaze me. Thanks and this is a great forum to save history. I will send you a iphone of the pump and I guess both numbers are the same pump but I do not know why different numbers. I hated to rip open the air tight waxed box on the other number but will if I need to confirm it to be a Romec RD-3350 R975-C1 pump…….now I just need to find some GAA pumps! Thanks for all the knowledge. Russ
Russ, I have Vol. 6, 11, and 14 for the radial-engined tanks. 1745781 isn’t listed but 0101732 is INTERNAL, engine fuel pump, assembly (for PUMP C92050). It is drawing number B197032. C92050 is PUMP, fuel, engine assembly (early M4, M4A1 with C1 engine) and it’s a rotary pump. FYI, there was a diaphragm pump meant for late tanks with C1 engines in addition to the diaphragm pump for the C4. The INTERNAL is not illustrated, so not sure what exactly this is vis-à-vis a complete pump.
So, just as you figured.
Gentlemen, I was fortunate to get a call about some tank parts…….we are deep in our Sherman motor replacement so parts are a rare item to get a call on. After a long drive I ended up with a mystery. I have all the manuals for our M4A3E9 #11965 but this pump is not in our ORD 9 for the GAA. I do not have an ORD 9 for the early radials that we guess this pump goes to. Does anyone have a ORD 9 for an early Continental? I have two different part numbers……G104-17-45781 and G104-01-01732. It seems they are both Romec Pump Co. #RD-3350. The pump is dated 3-43. It was packed for overseas in 1953?
Can anyone help to look up these numbers in their manual? The 15-1 cross reference says it goes on a Continental but I looked on my R975-C4 in the M39. That motor has a diaphragm fuel pump…….This ROMEC pump is a rotary mechanical pump so it does not fit the C4.
Thanks in advance in trying to dig out some cosmolene history. Russ Morgan
