Fuel Line Quick Disconnects

Has anyone used the "Jiffy-Tite" quick disconnects to replace the failure-prone ones on their GT? They look to be really high quality, a step above the Omega parts. They have wide application in race cars. Also, does anyone know the hose size on the RS/GT?

I think the Triumph guys use a Jiffy-Tite disconnect as a re-placement. Oh, and their stock QD screws into the tank.
I imagine they use Jiffy-Tite probably for the same reason BMW riders use Omega QD's. Because it is a direct replacement for the crap plastic quick-disconnects their respective manufacturers used as original equipment!

I think the true fuel hose size is in mm., but 5/16" is very close.

Don't waste your time....read this thread and purchase the Omegas. At the end of the day, you'll be much happier.

You can find the replacements here as well. Just a bit less searching (and self-promotion) involved.
Viton rings are the best for use with gasoline as well as withstanding extreme temperature changes.

quick disconnects

Thanks, gentlemen. I will get the Omega parts on order. I have to do a 24K service on my GT soon. That will be a good time to install them.

Larry,

Just a word of advice when changing them out. When you remove the upper-right plastic QD from the fuel line, be ready for a shower. It's apparently a direct line to the fuel tank and sprays out pretty good without a QD in the line. Have the clamp and new QD readily accessible. Keep your thumb over the open line as you work. I just changed mine last week. After reading countless threads on QD's, I never saw this mentioned. No big deal, but better to be prepared. Oh yeah...you might want to put that cigarette out before you get started.

I've posted pics of the QD's on another thread. There are also more of them here.

Here's one of the Quick Connects:


The male side is the part that fails:


Here's how they fail, the plastic cracks at the sharp edge where it reduces in diameter:


Here's what the replacement parts look like, along with the correct part numbers. Use a -VITON on the end to get Viton o-rings (these are Buna-N):


I only changed the male side, as that is where the failure occurs. As mentioned in several other threads on this subject, the metal QD is interchangeable with the plastic.

tolerances

I read about this issue last winter and went ahead and got the Omega Q/Ds as a precaution. I never (had to) make the change, but in looking back at my invoice see that I got the FT-LCD220-06. This is 3/8" o.d. as opposed to the -05 which is 5/16" o.d. Anyone know the "true" diameter of the line and whether I need to correct this with the smaller o.d.?

Thanks!
