Fuel Rail Leak

Post by silentk »

Just getting the car ready so I can start using it again for the summer, and I've noticed I'm getting a bit of fuel leaking around the fuel injector rail. It's on the near side of the rail :

It looks like it's leaking where the fuel pressure regulator (I think it's that anyway or is that the other side?) attaches to the rail. The bolts are done up tight, so is there a washer or anything like that in there which can be replaced?

Theres a rubber O ring.

Its also worth changing the o rings on the injectors at the same time.

Into the fuel rail yes, an O ring, but it could be the other lower connection which is of a metal conical nature?

Just a thought

I don't think it's the lower connection, I guess the o-ring would be a Toyota only part?
