1967 M20C boost pump not turning on. My mechanic is at a different field, so I asked a mechanic at my field to check it out. He said I need a new pump. He quoted me 1995$ for overhauled pump. Sounds excessive, so I wanted to do my own research. I need to identify which one it is. Also, any recommendation for overhaul, or where to buy a new one, would be appreciated. 
Thanks

Check www.aeromotorsllc.com, they have a good rep for rebuilding fuel pumps for a reasonable price.   Also supposedly a quick turn around.

Your photo is the strainer / selector valve. If you need that overhauled, send it to Lasar in California.

But if you need your pump overhauled, remove it and send it to http://www.aeromotorsllc.com/ as mentioned before.

I did the same with mine. They charge 450 $. You need to prepay the shipping back to you and provide an UPS return label with your pump. Also payment has to be done by a check. If you need it quick, they may have an overhauled one on the shelf and send you that one as an exchange unit.

BTW: The pump they overhauled works great.

Thanks ! I got in late last night hoping to get the model number. I guess the mechanic took the pump with him. obviously, I am not a mechanic. :D

ill get back here when I have the model number. I read some old thread about aeromotorsllc and was wondering if they are still good.

The photo is of fuel valve/strainer?

No wonder it doesn’t turn on.

The actual boost pump is located just behind the firewall, pilot side, there’s sheet metal piece that needs to be removed.

I also used Aeromotors and am happy with the results.  If it isn't turning on at all, I would verify that you have 12v at the spade terminal that connects the pump to the aircraft wiring.  My pitot heat stopped working and it turned out that the breaker failed.

Thanks for the suggestion. It wouldn’t turn on as usual, but I could hear a sound like a thump noise.

I guess I didn’t gain points as a reliable source on this forum. :D

So I went in the logbook to find anything. The pump was overhauled in 07. Reference number mentioned is 4140-00-21 ANV.

Not sure what that ANV means ??? Isn’t it usually 4140-00-21-A ?

Ill get the pump back from the maintenance facility on Monday, but I want to make some research ahead.

also…what’s the story with replacing it with a weldon pump ? What makes them better ? How do I get the equivalent part number ?

Thanks for all your help !

When I first talked to my Mx about Aeromotors for the overhaul of my fuel pump, he was not very enthusiastic. Then, he called them and found out the way they operate with checks and return fees and he was less than enthused... He relentlessly complied with the hoops and loops and we got the overhauled fuel pump within 10 days, which is good since I live in Canada and have to deal with Customs on both sides!

Ever since then, he always sends the pumps to Aeromotors to get overhauled as he's very satisfied with the quality of the work they performed and the overall experience. And my fuel pump, along with every one he's sent, still perform as expected at a third of the cost of a new one!

Overhauled in 07 seems like a young failure. A good overhaul should last longer. Do you fly around with it on all the time?

Engine start, takeoff and landing.

I bought the airplane this year, so I don’t know what happened before.
