I have since read that some builders have put sealant over the sender before enclosing in the wing. Now that i have to pull them out to do the mods I would like some feed back on how many just put them in and how many sealed there's. And if they did seal them what did they use.

Pulling the tanks for the upgrades after 18 months of flying, one sender was bone dry and the other had some slight blue (100LL) staining on it. It never leaked enough to drop fuel on the floor and there is only a small trace of blue on the skin below the tank. I think it came from a screw head and am hoping that a little more sealant under the screws again will do the trick. I do not want to pull the entire sender for a tiny bit of seepage. I would probably do more damage than good. -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 116.5 hours and holding (incorporating upgrade) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=287604#287604 ________________________________ Message 4 _____________________________________ Time: 04:52:39 AM PST US Subject: Re: Zenith601-List: Fuel Tank Sender Sealing From: jaybannist@cs.com Ian, I installed my senders with the gasket and the paper washers on the screws that came with the kit, no sealant. Neither one of them leaked. I did not use any sealant on the fittings, either. One side leaked and the oth er one didn't. Just to be sure, I would recommend using a very small amou nt of anti-seize sealant on those male fitting threads.

George ________________________________ Message 6 _____________________________________ Time: 10:24:43 AM PST US From: Jim Belcher Subject: Re: Zenith601-List: Fuel Tank Sender Sealing I pressure checked the tanks after I put the supplied seals in place, and used a water and dish soap mix to look for air leaks. I found a few, and sealed the leaks with Dow Corning RTV 736 heat resistant sealant. After the sealant had cured, I did another pressure check, and found no leaks. If there are no leaks when one does a pressure check, I'm not really sure where one would apply the sealant, and feel confident it was doing any good, short of smearing it on every place that might leak.
