Glenn Stevenson Posted April 16 Share Posted April 16 Glow fuel tank How do people stop air leak from the screw in the middle of the bung? Glenn Quote Link to comment Share on other sites More sharing options...
Andy Stephenson Posted April 16 Share Posted April 16 Assuming you have assembled it as per instructions, it should be tightened as much as possible, failing that new fittings are available. Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted April 16 Share Posted April 16 I can’t say it’s ever been a problem on any of mine. I wonder if you’ve got a hidden split or other fault? One thing to watch out for is the screw loosening, particularly after a period of storage so it’s as well to make it a regular maintenance check. 1 Quote Link to comment Share on other sites More sharing options...
Glenn Stevenson Posted April 16 Author Share Posted April 16 ive had it with lots of tanks, usually the ones in artf models, usually put a slec or dubro in and all ok. the one ive got now is a good fit in my model and may be difficult to find a replacement.

Martin Harris - Moderator Posted April 16 Share Posted April 16 Are you getting fuel leakage at rest/while filling or are you diagnosing this from air bubbles in the fuel feed? If the latter, then it may be fuel frothing due to vibration. ARTFs often have quite rigid mountings to their tanks. Packing the space around the tank with scraps of foam rubber can reduce this effect dramatically. I’ve also seen advice to add a few drops of “ArmorAll” - a car vinyl cleaning product but haven’t ever tried it - and a quick squint at the Halfords site suggests they’ve diversified the range from the original product, so take this advice carefully.

Glenn Stevenson Posted April 16 Author Share Posted April 16 when I test a tank I submerge it in water and pressurise it (blow into it) the bubbles come out around the screw hole, if air can come out then so can fuel. Quote Link to comment Share on other sites More sharing options...
