GT Fuel tank removal steps

I was in the process of trying to disconnect the secondary air injection to eliminate the "loud" backfires I was getting while using the Remus slip-on exhaust that came with the bike. I was able to get to the point where the tank was free to be lifted. I could only get to the point where I could lift the tank 1/2 way before the myriad of hoses and cables prevented me from going any further.
If I can get my big hand in there, what needs to be disconnected before lifting the tank any further? I can see the fuel lines, are these the fittings that should be replaced with the metal ones as a precaution? Are these fittings made to prevent fuel flow when I disconnect then from each other or will I see a steam of gas if the tank is not empty? What else needs to be done and are the electrical fittings easy to take apart or are there secrets to breaking the connections using one hand? I'm sure once you do it it is a no brainer but the first time is always a killer. Thanks for any hints.

It's easier if you pull the battery, in fact, I strongly recommend it. The disconnects are very brittle, so be careful. They are one way, anti-flow. There is a metal push tab on the male side (the side that pulls off) before it will disconnect. I'd replace these soon with the metal, like I said, they're very brittle.

The breather hose pulls right off. There are two electrical fittings with tabs on them. The tabs have to be lifted with a dental pick or small screwdriver and then the electrical fittings pull off.

Thanks Grif... I've read a few posts but don't remember the battery removal being discussed. I'll do that when I attack the project again. I had to put everything back together before I finished as I had a ride planned with some buds and didn't want to miss it. Think I'll order the quick disconnects so I'll have everything ready... Thanks.

I was in the middle of hell at the office when I wrote it. The metal push tab is on the female side next to the tank. You'll figure it out.

The metal quick disconnects are the best thing you can do for yourself. The LT's started breaking with age as they got brittle and fatigued. That would be disastrous on our bikes. When you pull the female side off the tank, you'll notice a white soup in the threaded recess of the tank. This is from teflon tape, just sop it up. Use teflon tape on the female side to the tank JUDICIOUSLY. Good luck getting the male side out of the tube.

FYI, a male side quick disconnect from an LT will work, though it doesn't have a ninety degree elbow. Found that one out the hard way on a Sunday afternoon.

This bike is such a joy to work on compared to the LT as it strips and goes back together so quickly.

Gas Flow

So the gas doesn't flow out when you disconnect huh?

No, that's what anti-flow means. Actually, the manufacturer refers to it as a "shutoff" option.

But Grif, they're not "one-way". Fluid can flow easily in both directions when connected, and in neither direction when disconnected.

I've replaced them on my GT already, and picked up some extras for my aux fuel tank connections.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Whaaaatevahhhh (insert hand movement here). I was in the middle of a melt down and it's amazing anything coherent was scribed at all. That's my excuse and I may, or may not, stick to it.

Ok - first, my apologies.....

I thought I'd bookmarked the info on the fuel disconnects, but can't seem to find the info. I've been searching the forum for a while (including the Hall of Wisdom) but can't seem to find the info.

Grif (or anyone else) - can you please post the info on the 90degree quick disconnect (one or two needed?) for the fuel line again?

Thanks,

Mike

Check this thread, especially post #1 (pics) and post #14 (correct part #'s). I've put these on my GT and they fit and work great.
