First flight on my M20E and I have a maintenance issue

[Marauder]

Thanks for the feedback everyone! You are a really helpful crowd. Based on the time to overhaul Vs. ordering a new one, I'm going to get a Weldon 18020-A pump new as soon as I can find a shop to do the work for me. I have just this week and next to spend flying (I'm between jobs) so getting the plane flying again ASAP is critical to me. At that point I'll have a Dukes pump that I can do whatever with. It'd be a shame to throw it away but I don't have much use for it other than as a spare and that's only if I get it overhauled first. Can I get the core value by sending it into one of the overhaul shops? Does anyone have any good ideas on what I can do with it?

Clay -- most of us long time owners have a closet of "stuff" that we took out for various reasons. If the Dukes pump can be rebuilt and will work as direct replacement for the Weldon (wasn't sure if you installed the upgrade kit or bought the Weldon that someone mentioned is a direct replacement), I would rebuild it and hang onto it.

If it can't be used again, you could rebuild it and sell it with the yellow tag or sell it as a serviceable core for someone who may be looking for a backup pump.

Marauder:

The Weldon is a replacement for the Dukes, either with the upgrade kit or the newer model (18020-A) that doesn't require the upgrade kit.

 

I think I'll save the older one for now unless I can get the full core price (AS&S says $350) for sending it in.  If I could, that would make this whole experience significantly less expensive!

 

On the bright side it looks like I can get my plane back this week, probably by Wednesday!  While I don't think this will salvage my planned flight to the midwest, I will get to do a lot of flying and learning around here!

Tip... When replacing the pump, be sure all the fittings are threaded onto the pump BEFOREmounting the pump into the plane.  Tighten the fittings after mounting it in the plane.

Good Luck !

Speaking of the plumbing down there...Anyone have any instructions on cleaning the inline filter after the Dukes pump. There was an SB that was for the install, but I've not seen it as a service item. Actually, untill I read the SB for the install, I didn't know it was a filter untill then. I have always cleaned gascalator and Inlet screen to the fuel serv, they have always been clean. I'll re-read the Install SB and see if there is any info in there...

222B was the filter install SB, no mention of servicing procedures.

Thanks,

Just remove the filter, unscrew the two halfs, look inside, if there is nothing in there put it back together. If there is clean the filter and try to figure out where the stuff came from.

Coming back from Oshkosh last week and my fuel pump did not come on at my planned overnight fuel stop as I entered the pattern.  Long story short, my Dukes fuel pump that had just been bought and installed 17 months earlier was not working.  Options were a "rebuilt" Dukes pump for $ 1,300 or a NEW Whelan pump, purported to be a drop in replacement, for $ 793.  (Neither price included shipping.)  

 

Whelan pump arrived overnight delivery and I was good to go by noon the next day, which was not a problem since I was planning to stay 2 days anyway (old home town- seeing  friends and relatives).  It was Whelan Pump # 18020-A  (from Aircraft Spruce).  

 

Per mechanic (who was not a Mooney mechanic), the Whelan pump was an easy install.  DON'T FORGET TO GET TWO (2) NEW O-RINGS ($0.28/each), too.  They are  # MS29512-06.

 

I have an E model (1965).  Make sure your mechanic double checks all the above part numbers to make sure you get what you need for your plane.

Also, Dukes offered NOTHING for their pump that went bad in under 17 months.  No core discount.  No partial credit for a part that used to last for 10 years (maybe wishful thinking from me).

 

Am happy with the Whelan pump so far.  It does have a different sound than the Dukes one, but to me it is the sound of saving money.  Plus, it was new, not refurbished.

Just like champion plugs going south in that last few years, I think we all need to choose Weldon from now on until whoever owns the Dukes lines cleans up their act.

My plane has a Weldon pump put on about 10 years ago. It's still working just fine so far...

Update:

The plane is up and operational again.   I ordered the Weldon 18020-A from Spruce yesterda overnight delivery. It arrived this morning and I got it and the plane to the shop by about 11:30.   They were done by 3:30, including a few other small things I asked for. Now when I put the boost pump on the fuel pressure instantly goes up to the green bar.   My old dukes is sitting on my kitchen counter (Yes, I'm single) waiting for me to store it somewhere.

This evening I flew another 1.3 hours of flight for training take-offs and landings and now I'm ready to explore the great big yonder

DrBill- GREAT comment not many know that little trick and struggle  after clamping the pump in-or cross thread the B nuts.

The boost pump was the first thing to go on my '69 E as well. Also on the first day or so of ownership if memory serves correctly.  Oh, how I've spent money on the old girl ever since.......

I Remember laying on the ice-cold tarmac with my A&P buddy outside one cold night in Decemember R&R-ing that old pump.  Also, I have been burned by refurbed parts several times so I usually just buy new.
