Hey guys,

My 306 Rallye has been sat up for a while waiting for me to get round to fixing it.
Went and started it up last weekend to move it and noticed a petroly odor. Sure enough, leaking out of injector 4.

Looked like it was coming out of the top of the injector/fuel rail.
The fuel rail has a bit of surface rust on it, so not entirely sure if its leaking or if the o ring has perished.

Anyone know how likely it is for that oring to have gone after sitting a couple years or if I'm gonna be looking at replacing the rail?

And side note does anyone have a good fuel rail sitting around?

Cheers
