Fuel Pump Part Numbers - T337F

[Learjetter]

According to Mikes Aircraft Fuel metering service and QAA in Tulsa…they’re all the same pump on the NA 337s. Expect 4 weeks and an AMU for overhaul. I can recommend Mikes shop…give them a call and ask about 337 fuel pumps.

Sometimes the shop might have an existing pump already rebuilt on the shelf and you can do an exchange if you’re in a hurry.

I have had good luck with Aircraft Accessories of Oklahoma.

Yeah, went with A A of Oklahoma. They did not have one on the shelf but said they could rebuild mine with a 5 day turn around. Sent it off yesterday.

I was not able to locate an exchange anywhere. Prices ranged from $1100-$1400 for the rebuild. Turn around times varied from 5 days to 6 weeks.

Hi, I had to replace both pumps in my 1969 T337D. It turns out Weldon makes a brand new pump for my aircraft. the PN is 18000-B 28V and it is $885 on aircraft spruce. I'm not sure about the PN for yours but If you haven't done this yet I would recommend going this route. Mine both work very well.

Thanks B2C2, but those are the electric boost pumps. I was looking for the primary, gear driven injection/metering pump.

Okay sorry about that. I didn't look up the part numbers but the cost was similar to what I was quoted for rebuilding the electric pumps. My A&P was surprised to hear that you could buy new ones for less than that, and they seem to work fine so thought Id pass that along.
