RELEASING FUEL TANK CONNECTOR ON 750 BREVA

I have done this without breaking anything. It is a two-handed
operation. This bit came from Mike Haven at MPH:

Un plug elec connector, start bike. This lets the pressure off
and it comes right apart. Push the grey back into the line,
then gently tug the line off.very little force is needed.

If you are forcing it or using pliers you are doing it wrong. Push the
connector "on" and while holding it on pull the gray lock-ring back in
the "off" direction. The connector should come loose. When you get it
right it pretty much falls off. When you don't it seems like you need
a jackhammer. 

It's a weird little connector. Somewhere on the site there are
pictures of a supplemental connector someone made to avoid having to
mess with the factory connector. If you pull the tank off a lot it's
probably worth considering. Breaking that little red outlet tube is an
expensive pain in the butt.

The factory uses a one-time-use “ear clamp” [for the fuel line] put on
by a special clamping plier.  They are made by Oetiker, a Swiss firm.
The clamps are not very expensive and they should be used for
replacement filters and lines.  An alternative are special clamps for
fuel injection lines from auto supply stores, with “rolled” edges to
prevent the clamps from digging in.  Do not use regular hose clamps.
They dig and cut the line over time and will fail.

There are other alternatives out there too.  For water lines, etc.  A
search should bring them up.  Later today I'll dig one up as well.

I had difficulty finding (actually I never found) any t-clamps or fuel
injection clamps small enough to fit the lines on my Breva. I ended up
ordering a bag of proper-size Oetiker clamps from some eBay vendor
specializing in soft drink machines. Seems like a bag of 10 was a
couple of dollars. I just used diagonal cutting pliers to clamp them
down.
