Fuel Selector Valve

[AmigOne]

From one day to the next the selector valve has started leaking in my 68C.  Talked to LASAR and they rebuild the valve and drain for $300.  This includes cleaning both, polishing the seats and changing the seals.  They do not sell any parts.   Does anybody know what seals are these and/or have a part number?  My mechanic already looked at the exploded view of the valve and did not find a part number for what it seems to be a gasket.

I think the $300 is OK and I'll send it to LASAR if I have to but being on the east coast, and knowing my mechanic, I think that he would want to do the job if the parts can be found.

The drain has no seal -- if leaking out the drain output it's a metal to metal conical seat.    Lapping would be difficult, but a tool could be built to polish the valve body.

You can let him have a go at it, and see if he can determine what the seals are made of and try to source one or reverse-engineer it.  I would just send it to LASAR instead because it might end up being cheaper in the end compared to paying your mechanic for labor to try to figure it out.

This is one of those items that you don't want to get wrong when it goes back together. I had Ivan James redo mine a few years ago, and as knowledgeable as he is, especially with vintage mooneys and that system, it was a 4 hr job to do right and I supplied the seals. It was tricky to get back together. While you probably have a fantastic IA, Personally, I would rather go down the road of experience on this one myself and just send it to LASAR. Let your guy do the R&R.

Mine was leaking around the drain when I got it and removing the bowl and cleaning the seat area fixed it.

Most likely it is not the drain since it is the stem of the valve that was wet and closing the valve made the wetness (and smell) disappear.  I will certainly ask my mechanic if he rather send the valve to LASAR but I'm sure that he'll leave it up to me.  He will not be offended, they are an excellent shop and they have plenty of work.

Mike_Elliot, for information do you have a part number for the seals and where did you get them?

They sold me the parts and I rebuilt mine. The drain valve is a conical metal piece but it seats against a rubber o-ring.

Be real careful when you pull it apart. There are two plastic seals that are not procurable.

I got them from either Don Maxwell or Willmar Air. Its been about 4 or 5 years ago, I just called them up and ask them to send me all the o rings, gasgets, etc (especially the o ring embedded washer that goes on the bolt that holds the bowl on) About $20 worth of stuff, if I recall, including postage.

I am pretty sure Don has all of this, as I got a few of them from him in Nov. for "stock". I don't know the part numbers, however.

I bought the parts from Lasar. Easy enough to rebuild, if you don't loose the two mini spring loaded ball bearings for the left and right detents, when taken apart. Mine didn't leak, but was hard to turn. Works great now.

The fuel selector in my C is very hard to turn.  I can do it, but have struggled in flight to get the tanks switched.  I made a handle out of a 1/2 inch PVC T.  I just keep it in the pocket on the left side and it works great.  But I'm wondering how hard it should be to turn the selector?

 

Thanks,

Paul

A child should be able to twist the selector lever.  If yours is very difficult, try lubricating it first, but prepare to possibly remove it for more attention.

Just happened to see this on Barnstormers.com.

 

I'm not sure what the difference is between the C and the E selector valve is, but it looks as though this guy may also rebuild since he wants an exchange.

 

Anyone dealt with this guy???

I believe he posted here in the past, but I don't remember his user name.  Was down in San Antonio but apparently moved to Canada.  He parted out an E on here and on ebay after selling it whole didn't work.
