This is a hard to find original fuel pump for a Fairbanks Morse N hit and miss or throttle governed gas engine. It is cast brass and is in excellent used condition with no cracks, breaks, or repairs. It has what looks like a new plunger in it and will need a barrel nut and some packing to be complete. It mounts with two holes 1 7/8 inches apart on center. It is part number 5RP3 and may fit several sizes of N or NB engines so please do your homework to be sure it will fit your application. It will always fit on your shelf for a spare. The pictures tell the story. These original fuel pumps are extremely hard to find in the wild or even in the collector network so if you need one here is your chance. You won’t be disappointed in any way. I can be reached at 262 573 193 1 if you’d like to talk about it.
