Gas tank fuel line fitting upgrade

I am interested in replacing the quick disconnect in the fuel line to remove the tank. The one used by MG is a cheap setup that is a pain in the butt to get disconnected. Does anyone out there know of a better solution, or replacement of the connector with a better quality unit?
 
I switched mine out to a Dorman 800083 Fuel Line Connector...5/16". This connector mates to the existing red outlet on the fuel pump. Cost is in the neighborhood of $6.00. You will also need a special tool to release the connector, also about $6,00. Both should be available at your local NAPA store.

Word of caution. Without a special tool to put fittings on the nylon fuel line it is a very difficult task. The special tool, also made by Dorman, is available on Amazon for about $80.

OK, I looked at Amazon links, and I don't see any real benefit for the Dorman over the existing fitting - what am I missing??
 
It disconnects easily, connects positively and if you do happen to mess up the inner piece that secures it you can replace it for about twenty cents.

Another, significantly more expensive option, is to put the steel quick disconnects, often found on BMWs, inline.
 
Thank you for the reply. How did you secure the fitting to the fuel hose? Did you use the Oetiker Clamps like the stock setup or something else?
 
The existing nylon line is a press fit. The Oetiker clamps are found on the fuel pump in the tank but the line from the tank to the fuel injectors is simply a press fit. This is where the tool I mentioned comes in. If you consider this option check out the web site at http://www.dorman.comto see how the tool works.

Some people have switched to the rubber line with clamps. I had access to the Dorman tool and chose to continue using the existing nylon line and not mess with the fuel injector ends.
 
The fuel line disconnect on the Norge is what gives production engineers such bad reputations. And well deserved these reputations are. My fuel line become so difficult to disconnect from the tank that it finally broke the little red outlet off the fuel pump assembly. I investigated the price of replacing the disconnect and the fuel pump and was immediately dissuaded from any further conversations in that direction. Being a properly trained 'forensic' engineer myself, I set out to see about not only repairing but also improving this setup.
I removed the fuel pump and drilled out the pot metal that was holding the little broken red thingy. I then tapped the remaining metal and screwed in a standard right angle plastic barbed hose fitting. I then used a short length of fuel hose with a quick disconnect sourced from Omega Engineering and forced a barbed straight through fitting on to the end of the plastic line going to the throttle bodies and tightened everything down.
Works great after 18,000 miles and is very easy to disconnect now.
 
Went on the Omega site and looked at the couplers, they look like they would do the job. Steven, which couplers did you go with?
Looks like the delrin ones were suitable for gas. Are they able to be purchased direct?
 
For those of you wanting to make this change:

so as someone who's joined the ranks of Norge owners who broke the little red plastic thing, can I confirm the specs on the parts you're using to replace it?

It's looks like an elbow with a 1/4 inch thread/tube size and a 5/16" hose size with barb. Can anyone confirm this spec?

Does re-tapping the plate and replacing the original with a fitting at these measurements mean I can keep using the original disconnect on the fuel line? or will the disconnect also have to be replaced on the fuel line to match the new part?

Thanks.
 
When I had my 2000 Triumph Sprint ST there was a problem with the fuel quick disconnect plastic fittings, triumph did a recall and replaced one side but not the other. A lot of the guys on the Triumph site replaced the fittings with these brass fittings. I'm wondering if you were to cut the Guzzi line back from the elbow and then insert a male and female brass quick disconnect fitting, would that solve any issues?

I think it'll be a winter project for me!!!
