My Stag was MOT'd last week and the examiner noted a "dangerous" advisory. It's about a fuel pipe which comes from a tee linked to both carbs. The pipe falls vertically on the left side of the engine and ends above the exhaust manifold. I assume its a fuel breather/overflow pipe but even after a look at the Repair Operation Manual I can't figure out its purpose. Anyway, I can see the examiner's point - any fuel coming out of the pipe will leak on to the exhaust with potentially dire consequences. Grateful for any help with these questions (and apologies if its been covered before - have searched for, but not found, the same question). What is the pipe for? Is it ok to simply divert it to the other side of the engine away from the exhaust ? is this pipe the cause of some of the Stag fires we hear about? Hope these pictures are loaded ok and help. Many thanks for any advice. John SDC12416.jpgSDC12417.jpg

This is the fuel overflow and should be a smaller diameter pipe that runs down and attached to the timing chain cover.
It goes down below the pulley so much further than yours and away from the manifold altogether..
Yours is also routed incorrectly,you need to see pics I dont have any sorry.. -
Hi John, it's the carb fuel overflow, it should pass through a "P" clip trapped under the timing quadrant drivers side bolt.

I have the same & yes it baffled me too.
The fact that yours looks a bit like a garden hose probably raised the MOT mans eyes too.
If it was the Black furry breather type pipe thats more common on older cars, he probably wouldnt have even noticed.
I only noticed mine when I had the air filter off so I could replace the fuel pipes.Comment

And as already mentioned........ yours is routed wrong.Comment

Hi John, I recently fitted a new one of these and routed it out toward the offside front wheel where I clipped it to a suspension cross member and the outlet now points backwards into an area where it can discharge safely. Looking at your photo I woulds say that you need to get rid of the low point in the pipe as this would hold a quantity of fuel before it can be discharged safely, a bit like a waste trap on a sink. The pipe should have a constant fall away from the carbs.

Sorry Graham, but yours is routed wrongly, though I don't suppose it matters. The correct pipe is black plastic like yours, not furry, that could get soaked in petrol and burn with some enthusiasm.
This is quite urgent ! Martin.

Does it go down the other side of the pully? I have never thought about it much before even though I have had fuel pissing out from this before I did the valves.Originally posted by martin View PostSorry Graham, but yours is routed wrongly, though I don't suppose it matters.

Although mine is just rather large looking black fuel pipe, I thought it was wrong & should have been the furry breather type.
The correct pipe does look like a bit of an afterthought on mine.
Guess thats just how they are supposed to look.Comment

Many thanks for all the replies. Should be easy to remedy. Need a bit of welding as well but hopefully back on the road soon! Cheers again. JohnComment

Yep, easily fixed. Don't weld the petrol pipe though John
