rich o 07-02-2012 12:18:49 66.220.233.8 Report to Moderator	, i have a stubborn leak in two different connections in my fuel system. both in lines coming from the filters, they seem to be thghtened all the way down, possibly leaking from the line were the compression nut goes over. is there a seal or compound that may cure these stubborn leaks? thanks for any advise [Reply]   [No Email]

The cure? They can't be remove and replaced...you'll have to cut them off, just before the "bulb" and install new ones, IF THERE'S ENOUGH LINE...and.. there is some "Rule" about tightening compression fittings.. hand tight, then 1-1/2 turns or so. If you've got flare fittings..look for a crack! [Reply]  [No Email]

It's very tempting to crank them down more than nescessary. Once they're deformed, it's a downward spiral. They drip a little - so you tighten them more - which distorts them more - which makes you tighten them more... [Reply]  [No Email]

You may even find it with a fingernail or knife blade. if its cracked its very hard to seal,about the only luck ive had is redoing the double flair. what happens is even though its really hard to see,when you tighten it it spreads apart.
