Fuel leak GSX1100

[Joseph]

Hi

Onto the teething problems of the newly rebuilt GSX1100

The fuel tap is leaking fuel, seeping out

The tap itself i renewed prior to taking the bike apart, so it is secondhand but a genuine suzuki item

Seal is new

I initially forgot to fit the sealing washers under the sacrements

But now that i have my problem remains

It still looks like fuel is seeping down the screw threads, its not pouring out but obviously no tolerance is possible here

Is there a trick i can use ? Thread sealing product ? Teflon ?

[TonyGee]

have you got sealing washers on the screws ?  ive used dowty washers on some of mine

Yeah the thing is i forgot them first time round (years since i took this bike to bits)

So putting them on after the first spilling i though it would be fixed.

But nope

There is a petrol resistant PTFE tape think it comes on a yellow roll  PTFE gas tape I think?

I have a tube of grey 3bond sealant, ive used that on some threads and it worked.

i'd look for the cause before resorting to tricks.

Just a few options, just narrow it down.
Tank is leaking, seal between tank and tap, tap itself, or the washers.

Mate had new washers leaking, turned out the mating surface for the washers was damaged.
Filed them surfaces on the tap flat, solved.

Propper troubleshooting skills right there, brother. Well played

Indeed

- tank was sealed before paint

- seal between tank and tap is brand new Suzuki OEM

- tap is recent, can't see it leaking from the body itself although once the fuel is weeping slightly the tap is all wet on the underside

I'll investigate the washer setup

No, he said "looks like".

Leaves all options open ...

to me that him saying he can see the fuel leaking from them !!!!  but if you wan't to split hairs

uhhmm ... all fuel leaks down and he comes here asking for advice.
Does not sound like he can diagnose it himself.

Now every forum gives advice, but the readiness to offer smearing kit or use PFTE tape boggles my mind.
Plenty of knowledge here, but if you would rather call proper troubleshooting splitting hairs ...
and offering sealing kit .. 

does not immediately place you in my list of proper mechanics giving sound advice

I don't care what list you place me in !!!!!!  putting a bit of sealant on any thread thats holding a gas or liquid isn't a bad thing. if it improves the chances of stopping a leak then all good, especially petrol over a hot engine.

that's exactly what i mean.

Sealant is NOT the proper solution to stop a gas leak.
Now i know for sure what list to place your advice on

I would use some soap to stop a small fuel leak. Works very well.

What list does this place me on?

the list of people i hope not to read about in the news ...

Some 8 years ago i read about someone with a restored GS1000 that caught fire.

I called them on behalf of the club i was a member of to offer help.

They smeared the petcock.
It started leaking, and there probably also was a shortcircuit.

It's in Dutch, but the pictures say enough.
Please don't F around with botched solutions and find out, especially with gas ...

I often put a bit of sealant on the fuel tap screws along with new washers, even though I know the washers will do their job theirs nowt wrong  with a bit of extra piece of mind knowing theirs less of a chance of a leak, especially when it comes to petrol.

Regardless of what the other guy says, when you buy a new pingle fuel tap, it comes with hylomar & instructions to liberally coat the bolt threads to seal them. It's also standard practice in aerospace to use sealant on bolts when they go into an integral fuel tank.

Anyway when I had a similar problem on my bike, I replaced the washers with new copper ones & coated the bolts heavily with hylomar. No more seepage.

Presumably you've never used an aircraft filler cap with a bolt-on fitting ring. You have to put sealant (I use 3-bond) on the screw threads to stop fuel coming up through the threads. Problem with 3-bond is getting the bloody stuff off when components are dismantled.

In the notes that come with a Pingel tap it explicitly states to use PTFE tape on the threads and to experiment with different amounts of tape to get the tap correctly aligned and leak free. It sounds like a bodge but it works.

You are right Tony, so here goes.

first, i try to follow if you don't have something positive to contribute - don't.

I broke that, and said several things i should not have, in a way i should not have.
I am sorry about that, and apologize for that.
I was tired and went too far, something rubbed me the wrong way.

Ofcourse, things like petrol resistant kits ARE made to help with petrol leaks.
Applied properly, it's a good thing.

My keyboard warriorism is something i never do, uncharacteristic for me.
I am sorry for that, it really is the first time i trolled a thread like that.
Sorry to OP also.

And you guys went easier on me for that than i deserve ... thanks.
For the first time my contributions lead to a thread i'd rather see deleted because of them.

Don't sweat it mucker, we've all been there. You've apologised, enough said.
