Hello all, I am looking into a buying into a Mooney 231 it has 2 items that will have to be addressed tank strip and seal ADS/B solution So what are the best options and cost associated with them. The aircraft has a Garmin Panel including a 480 and MX 20 so we have wx data from XM just need out. Thanks in advance DavidA

Folks, Looking for some advice regarding a weep that has developed in my left fuel tank. Appears to occur when the tank is full. weeps from the hole on the lower area of the leading edge near the wing root. Plane is based at KVGT (North Las Vegas)...recent arrival there. Searching logs to find out when the last reseal occurred. Basically looking for either a local A&P that would be willing to help me do the work to fix this or a local shop capable of taking care of the issue (prefer the prior, not the latter). Haven't noticed any fuel smells in the cabin but also don't like things that leak. Seems to only occur when tank is full. Right side does not exhibit this behavior. Regards,

We fly a Mooney M20E and would like to have long range tanks, for a total capacity of around 90 gallons. The main purpose would be an 'once in a lifetime' flight from the US to Europe and back. Since our Mooney has been fitted with fuel tank bladders, Monroy long range tanks are no longer an option. Griggs / O&N bladders would work, but they would add only 10 gallons and are therefore too small for us. Are there any other option, I am not aware off? Oliver

I posted about a fuel smell in my cockpit a while back when I bought my M20K and just have been keeping the right tank below full up until now in order to not have to deal with it. It has worked but all of a sudden recently I can only fill the tank to about 18 gallons before getting wet carpet on the right side of the plane. Time to get this fixed. I did a lot of searching online and in this forum and I see Weep No More in Willmar, MN, WetWingOlogists East in Fort Lauderdale, FL, and Propellorhead Aviation in Winter Haven, FL. Wondering if anyone knows a reputable shop a little further north on the east coast? The plane is in South Carolina at the moment and I'd like to stop somewhere on the way back to New York (where I live) to get the tank seal dealt with. I'm open to having it patched vs completely resealed if that's possible.

I looked through the Mooney forum for this answer but didn't see anything specific. Does anyone know if you fail to top off your fuel tanks (when you hangar or park your plane), does that eventually cause leaks? I spoke with someone at my airport working on their Mooney and they were doing a reseal of their tanks. They mentioned that if you don't keep you plane topped off that the top seal becomes brittle and the seals are more likely to fail and the tanks are more likely to leak. I didn't think keeping the tanks topped off would keep the seals from failing. I assumed that the failure of the seal was due more to age, the seal just becomes old and more brittle, and when the plane is exposed to constant heat (or constant extreme cold) sitting on the ramp, the heat (or cold) eventually dries out the seal and it fails. ( I have also heard hard landings may be a culprit) I keep my Mooney hangared and so far, I have not had any fuel leaks (knock on wood), however, I do not keep it topped off and I don't like to fly with the extra weight when I don't need to. Most of my flights are under 300 miles. I generally keep about 50 gallons in the plane. Also, I have long range tanks. I never top the long range tanks (If I ever topped the long rang tanks it would eat up a lot of my useful load). So on long trips I just put 5 or 10 gallons in each long range tank after the mains are topped off. If topping the tanks off helps make the seals last longer then I guess my long range tanks will go first because I never top them off? So after all that longwinded explanation, does anyone know whether the failure to top the tanks off really leads to early seal failure and, consequently, a fuel leak or is this just an old wives tale? Thanks.
