Spent the last 2 weeks of July parked on the ramp at KLRO, Mt. Pleasant SC.  We had many strong storms, and in one case the runway was NOTAMed closed for 20 hours to repair lightening damage at the approach end of 35. 

When I left I didn't have a trace of water in either tank.   I currently have standard o-rings installed, changed annually.

My annual is coming up and I considered buying these O-rings.

I just spent the morning assembling more Shaw 431/531 and Shaw 416/516 fluorosilicone fuel cap kits. These are the first products I ever started with my store. These are simple but extremely effective

As long as you maintain your o-rings, your fuel caps should not leak. I’ll make sure you get the right ones.

My wife and I just completed a cross country move/new job/new baby and this is when we think things got jumbled up.

Spent several days last week parked in the daily thunderstorms on the Carolina coast. Some were strong enough that the house was shaking. The grass field was saturated enough on arrival that the far end almost bogged me down, I had full throttle (28") to barely move. Then we had more storms every day. When I left, there was nary a drop of water in either tank, but I did walk around the runway to make sure I could depart solo with no bags and half tanks.

Sure made me glad I put in your fine blue orings back in January! 

Thanks for the PIREP!

Two more Mooney aircraft equipped with high quality fluorosilicone o-rings. Potential fuel contamination avoided! Message me to order yours today!

We learned at the MooneyMax conference last week that most of the water leaking into the tanks goes down the center shaft with the small o-ring because many times it does not get changed with the big outside o-ring.

A simple check is to look in the depression in the center of the cap around the lift lever after a rain. If there is no water in the center of the cap it leaked into your tank.

+1 for these o rings.  Clarence put a set on mine during the annual this year and I have not sumped a drop of water from the tanks since.
