75_M20F Posted February 7, 2019 Report Posted February 7, 2019 (edited) Where is a good place to get the electric fuel pump overhauled? Mine has gone inoperative in my 75 F. Or get a replacement. Weldon Pump Part no. A 8153-A or A 8163-A. The part number is hard to read. Thank you. Edited February 7, 2019 by 75_M20F Quote

Shadrach Posted February 7, 2019 Report Posted February 7, 2019 I second Scott’s advice. They recently did my dukes pump. Quote
N6018Q Posted February 7, 2019 Report Posted February 7, 2019 +1 for Aeromotors http://www.aeromotorsllc.com/aeromotorsllc/products.aspx They did mine last year for ~$400. Fast service, excellent work, very responsive (especially for a relatively small operation). Quote
75_M20F Posted February 8, 2019 Author Report Posted February 8, 2019 Thank you. I have called aeromotors and I will have them do the overhaul. Quote
Jim Peace Posted February 8, 2019 Report Posted February 8, 2019 I bought a new fuel pump from these guys: http://cjaviation.com/contact-us.html almost 5 hundred hours later and works perfect...... Quote
Yetti Posted February 8, 2019 Report Posted February 8, 2019 Clean the filter that might be right next to the pump. Clean the finger screen in the fuel servo while you are waiting for the return from Aeromotors Quote

Clean the finger screen in the fuel servo while you are waiting for the return from Aeromotors There is no fuel filter that I am aware of. There is a screen in the gascolator which is between the tanks and the boost pump. There may be an additional screen inside the servo that I am not aware of but if there is, it's likely not field serviceable. Quote

Just saw it the other day as I was moving some spare, unused parts to the airport and out of my house. I think it is about 5 or 6 inches long and about an inch in diameter. I’ll find it later today when I get out to the airport and see if that is what it was. Sent from my iPad using Tapatalk Pro Quote

For the dukes there is a SB that puts a filter right next to the fuel pump. There is a finger screen in the fuel servo that is supposed to be serviced per the 100 hour/annual. Quote

There is a finger screen in the fuel servo that is supposed to be serviced per the 100 hour/annual. You're correct about the servo, I've never been there when it's pulled, so I've learned something. I looked up the Dukes AD and the filter you mentioned is only needed on the 19A suffix Dukes pumps. I am betting it was due to the potential for the carbon vanes breaking and going down stream. I don't think Dukes uses carbon vanes on any pump at this time. The alternate method of compliance is to install a different model number pump, no filter needed. Quote

Many vintage Mooney’s flying around with Weldon pumps retrofitted. If you go back to your logs, I bet you can find when the installation occurred. Quote

He would have sold me a Weldon but told me the upgraded Dukes was the best pump Quote
75_M20F Posted March 22, 2019 Author Report Posted March 22, 2019 (edited) I am reporting back after having my Weldon fuel pump overhauled by Aeromotors. Fuel pump was reinstalled and worked for one day then went tits up, I had to have my mechanic remove it again and sent it back. I just received it back, lets hope it works this time.

Yetti Posted March 22, 2019 Report Posted March 22, 2019 sad face. sure it was the pump and not electrical circuit? Quote

That was my first thought, (the electric circuit or the on off switch in the cockpit was perhaps the problem). My mechanic did some trouble shooting and determined the problem was a dead pump not the electric system as he was getting power at the pump wiring. Quote

Any chance there was trash in the lines? Were the lines flushed? Could have taken it out the first and second time. How are the fuel samples. Quote
GDGR Posted March 22, 2019 Report Posted March 22, 2019 I’m nervously waiting the result. My Dukes 1499-00-19 went to Aeromotors this week for overhaul. Quote
