My boost pump is 28V, parts manual lists it as Weldon A8613B

Sounds much more manageable to remove the access panel, then will be able to confirm source of the leak. I always take photos during disassembly to assist in putting it back together.

I didn’t think any fuel leaking from anywhere near the engine is common or normal, I was surprised by mechanic’s reply. I did see that the outer side of the access panel was screws yet the gear door hinge was the inward side, otherwise I would have simply unscrewed it. It does not look trivial to remove as mentioned by kortopates, thank you. Any idea how difficult it is? I’m not waiting my AP to come back, I was already uncomfortable by his low priority concern. I will have a local guy confirm cause and get overhauled unit or mine overhauled. Thanks to all to who gave their thoughts.

On the day I picked up my 93 J from annual, I noticed a slow drip of fuel behind my nose wheel and forward of my fuel sump on ground, perhaps a drip every 20 seconds. Shutting off fuel valve stops it. Turning on boost pump causes it to leak more. My AP states that it’s the boost pump seal that can leak in cold weather, I’m in Florida and weather has been seasonally colder in recent days. He states once weather gets warmer in a few days it will stop and its “common” for Mooney’s. I’ve not seen any such posting on this “common” problem on Mooneyspace and have only had the airplane 1 year but it never leaked before. He says not to replace the pump “till it needs it”, I’m not sure what to believe, I flew it once and it dripped at my destination. I would understand the issue more if my wing fuel tank was leaking, but this one is closer to the engine. It appears to be a Weldon A8163B, $1269 from Spruce. I haven’t checked yet whether it’s under an inspection panel or the one piece belly, but believe once I get access to it will be able to see where it’s actually dripping from. My AP is on vacation till second week of January. I would appreciate any thoughts on this.

I am fortunate to have Bob Bramble at my home field, he overhauled my AI last year. My DG currently is a bit over 10 degrees off now, going to have it checked out.

On my 93 M20J, my King HSI DG is off about 10 degrees from my compass that matches the compass rose at my airport. The remote compass sending unit above inspection plate in left wing has a circular sliding adjustment available, yet only provides about 3/4” total travel, perhaps about 20 degrees. When I attempt to turn the unit to align my DG, I’m limited to about 10 degrees east of 360 degree north. I don’t see a simple way to re-install unit in different orientation so that my available travel is more centered. I must be missing something to do.

M20FanJesse, please stop hustling me for your publication!

I’ve dealt with other vendors in similar circumstances and have learned to just walk away, regardless of my desire for the product.

Forgetting the potential special pricing, how much do these units typically cost?

I’m looking for a WX-900 if anyone has one. Scott

I have a M20J at SRQ looking for a partner, you won’t find a nicer airplane, needs nothing, 1993. Still interested? Scott

I have a newly purchased set of 3” extensions and have reconsidered whether I should have purchased the 1.5” instead. So I may be interested in swapping the 3” for 1.5” or possibly selling outright the 3”, but not sure. My concern is I may add a partner to my plane and fear he might be too tall and hesitant to install the 3” extensions until I know better. If it were just me flying I wouldn’t hesitate to install the 3” ones.

Selling a used 650 and buying a used 750 is very expensive. I just bought a Garmin Aera 660 and it is “aviation grade” mounted on my yoke using much less space than my iPad Mini.

I have a GTN 650 and GTX 345 but the screen size is too small on the 650 to read anything on the map. I wish I had a 750 but the 650 was installed before I bought the plane. A Mooney friend has the older Apollo MX20 (Garmin bought Apollo and replaced it with GMX200) in his plane connected to his GNS 430 and it works great. The MX20/GMX200 is a large screen. Im considering purchasing a used GMX 200 and installing I’m my 201 for map and traffic, or I could subscribe and get charts for the GMX 200. The unit is not supported by Garmin anymore but since it’s only acting as a display I’m not so concerned given the lower cost. Used GMX 200’s sell for $2k -$4k plus install. I use an iPad Mini with ForeFlight connected to my 345, but would prefer to have a panel mounted sunlight readable large screen that doesn’t freeze or get too hot. Anyone have any wisdom to share on this thought?

Friend sent me this today from Okeechobee.

Alan, does the GMX-200 connect to a GTN-650 for map or GTX 345 for traffic? scott

Please add me

I have a KAP 150 autopilot, GTN 650 and GTX 345. My AI is KI 256 and King HSI. It’s my understanding my autopilot can connect to a G5 replacement of my HSI, but that the G5 as AI won’t drive autopilot. Can someone confirm this? My AI is acting up, and I’d prefer to replace it with G5 rather than overhaul 23 year old unit. Thanks

Hard for me to question mechanic on this topic. The flush bracket itself adds size to the equation. The unknown behind the panel will be resolved shortly.

I met with the AP today and held a JPI 900 flush mount bracket in the area right of the altimeter, it does not appear their is enough room to add that bracket without affecting the neighboring instruments. Won’t really know for sure till the glare shield is removed and see the clearance available. If he mounts it raised, not flush, he can punch a new 3 1/8” hole just right of blank hole at his shop, if we try flush mount it involves removal of all instruments and taking out the panel to an avionics shop to cut the rectangle flush mount hole. The raised installation is the easier way and still would be tight, and I think I am giving up on fitting the flush mount bracket. If I second guess not installing it flush I can always try it at a later time. I have a large available area right of the radio stack in front of copilot, but I want it in front of me. Anyone think I have given upon flush mount too soon?

I’ve not had time to consider the Stormscope options yet, I’ve been told, perhaps incorrectly, that once I send it in only option is a full overhaul, not just a repair here or there. At $1,200 I’d do that tomorrow.

As I understand it, the JPI 900 unit is designed to mount in a standard 3 1/8" hole, yet it's full display is offset from the unit that fits in the hole. So if one wants to mount it horizontally, it needs spare room on left side of unit, not right, and I would have to either mount it vertically or mount it upside down for it to overlap right. My best choice here is to flush mount it, just right of the blank plate I have and have the round hole made into a rectangle hole and purchase the flush mount kit. Those people that only have room right and want it horizontally need to install it upside down and have the buttons on the top rather than bottom and JPI logo upside down. I don't think my AP will be able to move any instruments and take out the stormscope without having him put my airplane back together and have me fly it to another field with an avionics shop. Thank you to all that contributed their thoughts.

Although I’m in Sarasota, the only hangar I could find was at Avon Park, home field of Phil Jiminez (PJ Aircraft Services) that did my pre-buy and is installing the JPI 900. No avionics shop here. I prefer it landscape with buttons on bottom. The airplane is on jacks for other upgrades and since the 900 is primary JPI is taking their time sending it to us. I will use 900 more than 2nd glideslope and the upper position slightly better viewing. Gear handle won’t be an issue as it will be in up position most of time I haven’t made the call to try and fix stormscope that has no brightness, doubt I will, but removing it doesn’t give me an option. I believe mechanic desires to put under gear handle and have it partially cover blank plate left of it, or spot right of altimeter, it won’t be very clean.

I have a Mooney 201 that I've owned for a month and am getting a JPI900 installed this week or next. I'm looking for recommendations on placement for those of you that use an engine management system already. The unit can be installed portrait or landscape. It appears to me that landscape is the better orientation, yet I believe portrait will fit better. I've attached a picture of my panel. To the right of the altimeter and above the 2nd glideslope is an empty hole with a blank panel over it. Also available is the area to the right of that below the gear handle, but that would involve cutting a hole, I don't know if that is easy or not, or has to be done only at an avionics shop. My AP is doing the installation and no avionics shop is at the field. Below the spot under the gear handle is an inop Stormscope, and the center stack has a GTN650 and GTX345 along with KAP150 and 155 2nd radio. Installing landscape in the open cut slot right of the altimeter might infringe on the altimeter, I don't know. My thoughts were that the area under the gear was best and gave me future options to use the other spots for G5/Aspen potential options of moving instruments. Thank you for your consideration.
