Snagger Posted February 2 Share Posted February 2 Hi folks. I’m hoping to be putting the 109 back into service later this year. Last time I went to exercise it, it started but soon died and wouldn’t restart, even with two cans of fresh fuel into the main tank. I suspect it is fuel starvation, possibly a hole in a fuel line or maybe diesel bug or fungus. Either way, the system is going to need stripping and cleaning, and I’d like to finally sort the weeping from the seams on all three tanks. They aren’t that rusty, perhaps a little just between the skins and cradles where the diesel has washed away the wax I applied. Rather than replace them, I intend to clean and line them. POR15 is one option, but there are others. Does anyone have any experience of doing this, any recommendations or know if one kit’s degreaser and prep solutions will work on three tanks, needing just more sealant?

miketomcat Posted February 2 Share Posted February 2 I've used the por15 kit on the second tank on the 110 about 8 years ago. I used it inside and outside (even though they don't recommend it outside) it sealed the weeping seams and is still fuel tight. I would happily recommend it.

Eightpot Posted February 3 Share Posted February 3 I used Por15 on a rusted 30 year old fiat panda 4x4 tank that was covered in micro pin holes and had a bad leak around the seam - it worked really well and has lasted about 5 years so far. 1 Quote Link to comment Share on other sites More sharing options...
muzaz Posted February 3 Share Posted February 3 If you have friends working on aircraft you might borrow some PR1440 polysulfide sealant. Quote Link to comment Share on other sites More sharing options...

Hoping to jump ship this summer, so will have to forge new contacts, but that could be a good idea, at least for the front tanks with their large filler holes. Rear tank will need a liquid sealant as the Series senders are quite small diameter, preventing tools inside the tank. Pretty specialist knowledge, that - not Lufthansa Technik, are you?

You can thin it with acetone to the consistency you need and pour it...you won't find it in the instructions 😜 27 minutes ago, Snagger said: Pretty specialist knowledge, that - not Lufthansa Technik, are you? Yes, was there, moved on to Srt. 1 Quote Link to comment Share on other sites More sharing options...
