One of the fuel disconnects failed and I went looking for a replacement.

I found that a replacement from BMW was going to cost approx $25 for 1/2 of the coupling, so I looked around here for a better/cheaper source for the Quick Disconnects.

After reading a thread here on metal disconnects, I decided to replace all four pieces with with replacements from McMaster/Carr.

I also ordered 1 pkg of 100 orings - of the Viton material (best for gasoline) - so I can replace the orings each time I remove the fuel tank (at least yearly for brake fluid replacement).

So here is what I bought from McMastrer/Carr -

- 5012K672 Acetal Quick-Disconnect Coupling Socket, 1/4 Cplg, for 5/16" Tube ID, with Valve - 2 each $ 13.34

- 5012K712 Acetal Quick-Disconnect Coupling Plug, 1/4 Cplg, for 5/16" Tube ID, with Valve - 2 each $ 11.72

- 9464K16 Viton® Fluoroelastomer O-Ring AS568A Dash Number 011, Packs of 100 (Same as 9464K342) $ 6.32 for a pkg of 100

My total was $31.38 + a few bucks shipping.

Here are a few pics-

The new parts -

A closeup of the new disconnects -

The old disconnects are black -

The new disconnects installed

I lubed up the orings with a light coat of vasaline to allow them to come together without any binding.

Also, make sure that you use new fuel injection hose clamps (not typical hose clamps) - I bought 4 clamps at NAPA for a few bucks.
