rogerbacon Posted June 8, 2009 Share Posted June 8, 2009 Hi All, Recently I have found a lot of water in my gas tanks and I think I have gas caps that are leaking. What kind of gas caps do you recommend and where can I purchase them? Quote Link to comment Share on other sites More sharing options...
rogerbacon Posted August 6, 2009 Author Share Posted August 6, 2009 I measured the size of my current gas caps and it was 3". These http://www.aircraftspruce.com/catalog/appages/lwsprlfc.php are 70mm, which is just a little under 3". Is it likely that my measurement was off by just a little and these would fit? Are the openings pretty much standard size? Last question: we don't need vented gas caps because we have the fuel vent at the back of the plane above the passanger seat, right?

philc1 Posted August 7, 2009 Share Posted August 7, 2009 Roger, I don't know about the link you posted but I saw you didn't get any (public, at least) replies to your post. I ahven't flown my long-ez yet but I do have some nice fuel caps that I would recommend to anyone. You must lift the tab and then twist it 90 degrees before the cap will come off, They are a little more expensive, but in my case, my confidence in the cap more than makes up for the cost. http://www.aircraftspruce.com/catalog/appages/aerofuelcaps.php I have model C36L but A36LFF should work too. You can go for the locking option too for a few more dollars. Not sure that's worth it.

Kinnerhatz Posted August 7, 2009 Share Posted August 7, 2009 Roger, If you change to a different type of cap you will have to cut out the existing filler neck and bond in a new neck designed for the new cap. There is no standard filler neck. If you have the original Rutan style gas cap -- the one where the cap engages a small rod running across the filler opening -- then you may just need to replace the o-rings. There is one large and one small o-ring in each cap. I have some of these and will send you a set if you PM me your address. Kin Quote Link to comment Share on other sites More sharing options...
