Fuel Rail Removal

[Mogan]

I'm working on the Audiovox CC install. Have most things torn apart, servo is installed. Tank is off (done that too many times), but I've never removed the fuel rail. I assume that's what Yamaha calls the "fuel distributor" in the manual?

I have the manual, but it only offers a dissassembly sequence.

Any tips or watchouts on this step?

The rail is held down by the two screws with aluminum standoffs or spacers underneath. If you loosen the screws and lift up the rail you can succeed in dropping the spacers off the screws. Don't ask me how I know this. A piece of duct tape strategically and temporarily applied will hold them to the rail so they don't fall off. Other wise, pretty straight forward. Loosen the sensors, hoses, wire connectors, take the two screws out and lift it up.

Man, this is a heluva lot more straightforward than the manual makes it look. Thanks!

Be prepared for lots of gravel or sand around the injectors -I would suggest that you use compressed air to blow the 'wells' clean before you remove. This will reduce the chance of foreign material dropping into the ports.

The injector tips have a thick o-ring around them to seal into the ports - when you lift the rail out, the o-rings will either stay in place in the wells, or lift out with the injectors - in which case they can drop off and go bouncing where ever they feel like going. DAMHIK.

There ain't nothing like chasing a black o-ring into the deep, dark recesses of your engine, or across the garage floor to under the tool bench.... :blink:

And it is easier to reinsert the injectors into the injector bores if the o-rings are lubricated with a little engine oil....most any type will do....LOL.

Make sure your screwdriver fits tightly on the screw heads. These are quite snug, and the heads aren't hard to strip.

ALL helpful suggestions. Pulled the rail off before I got the last two. No troubles so far except the rail screws were really tough to loosen. Thought I was going to strip the heads before they finally popped.

Got the throttle linkage all done, too. That was indeed tricky, but the threads on the topic were invaluable. I ended up using 5 beads and made a minor bend in the tang to make the smoothest possible linkage travel.

Starting vacuum and electrical next. Thanks again!!

Mogan...where you at?

(people ought to be required to post that info in their profile)

I need to install my Audiovox and since you're in the process, I thought you'd be ready for another install.

When I put the fuel rail back on, I must have had one of the O-rings cocked. Had a nice loud whistle when started after reassembly. I used a stethoscope to find the buggered one but it was easy to see the cut ring when I pulled the rail off again. I think a little oil would have kept them in the right place and saved me some trouble. Ian, Iowa

I use a hand impact to break the screws loose. If not available, an old screwdriver tapped with a hammer can help. Mess up the heads and you're screwed (hehe)
