Tri power lines leaking again

Re: Tri power lines leaking again

I use the permetex #2 in a tube. It's the black sealer for threaded connections like block plugs etc. never had a problem.

One thing to keep in mind is that sometimes the seat where the flare seals can get a groove from previous use causing a slight leak no matter how tight the line.

this is why you should use those dead soft copper flare washers. one side will seal on the fitting and the other side will seal the tubing flare

Re: Tri power lines leaking again

I use white lubriplate, stay away from teflon & other "sealers". There is no good repair for a striped out bowl-that's why Holley sells replacements. But if you insist on "repairing" a zinc potmetal bowl, then I wish you luck.

a stripped holley float bowl is a very hard repair because the casting is very thin around the threads. Qjets can be repaired.

Yes, but if one is going to do it himself, he better be planning on doing a LOT more than 1 carb. The Helicoil kit for this repair is "rather expensive".

Loctite 545 thread sealer stopped all fuel line leaks on my car. Available from industrial supply houses. Resists motor oil, unleaded gasoline, brake fluid, ethanol and water-glycol. No problem disconnecting the fitting. Once I saw the performnce on gas lines I started using it on oil line fittings too (distributor lube line, oil pressure gauge line, oil pan drain plug).

Once-upon-a-time, even though I had only one carburetor ever needing this repair, I thought very seriously about buying the kit "just to be able to do it myself". Believe it or not, sensibility overtook me and I decided to let someone that already had the kit and the experience to use it do the repair. Every now-and-then that happens to me.

after you get the heli coil kit to do it right you need a milling machine

Re: Tri power lines leaking again

Good advice Ken. The guy who restored my carbs originally is doing it FOC as a good will gesture but i think i'll buy new bowls as a precaution (they take a while to get to Australia). With possible future judging in mind i am trying to replace parts correctly, so would it be better to look for correct date restored replacements from US or is it ok to replace just the bowls? Could you suggest a good place to get either of them them from?

Re: Tri power lines leaking again

Thanks Clem,

Interestingly i quizzed the repairer who said he would not suggest copper at all. The seals he has given me, his words, have a rubber coating and are Holley replacements. Could this be the problem?

i am talking about the copper gaskets for the gas lines flares to the gas line fittings and you are talking about the gaskets for the float bowl to float bowl fitting . two different items

Re: Tri power lines leaking again

Thanks for all the great advice and comments. I'd like to hedge my bets and purchase some bowls just in case. Can anyone point me in the right direction? There are some NOS bowls available from on eBay, or would it be better purchasing new from a reputable supplier?

Re: Tri power lines leaking again

Hi Ken,
Is the Lubriplate a brand name or the type of grease. Excuse my ignorance but we have white lithium grease available locally, is it the same. I remember as a very young mechanic some 30 years ago using this type of grease on door locks, hinges and Window mechanisms. Am i right in guessing its still the same?

That is what I still use on latches ETC. It will not wash out and stays where you put it unlike WD-40. Not sure that it would stop a gas leak in a fuel line. I have NEVER had much luck stopping a leak when the threads are warn or stripped.

Re: Tri power lines leaking again

Yes it is a brand name-but you can use your white lithium. The grease is NOT to plug leaks, but to allow the mating parts to tighten without premature siezing.
