Default Damaged a pipe... Can it be replaced or repaired?

Hi all, it's been a while!

I was under the car yesterday with a grinder and wire wheel. Despite my efforts to be careful I have nicked the pipe with it and put a hole in it:


Is this just a breather that could be duct taped over or am I going to have to replace it? It looks an absolute nightmare to get out due to it channeling in through the body of the car from the filler neck area...

If it does have to be replaced, what's the correct way to release this catch on the pipe connector?

anything fuel related i would suggest you replace. You will struggle to patch that to a really satisfactory standard.

Also the area looks so corroded that you would be better off stripping it all out so you can address it properly.

I'm getting in OK for dealing with the corrosion to be fair. If it's just a breather pipe I'm tempted to use this:

But there is that niggling doubt.

upto you.

Its part of the fuel system, either venting into the charcoal canister of part of the expansion bladder.

Damaged pipes in the fuel system are a no no as far as i am concerned, but repairing it may work for a time.

Have you looked to see if there is an inner pipe as the outside looks a little like a shroud.

I'll double check but I don't think so. You're right though, I should replace it.

I'm sure people delete all this stuff on track cars though...

I have but then i have replaced the tank with an ATL.

Removing it on a standard tank can be more problematic, the tank needs to vent properly or it will start to collapse. also part of it is for fuel extraction and roll over protection.

Its not as simple as ripping it all out.

Off road racers just put their vents to one of the one way vacuum valves swiped from a brake servo, to let the tank suck air in and not spill on rollover.

However, this makes no allowance for a full tank of cold pumped fuel expanding on a hot day

Fair point.

It just looks an absolute bastard to get that pipe out where it goes through the body. Going to have to try and get a replacement from a breaker. Can't tell if you can get the individual pipes of have to get the whole bunch as one. Looks like they use some god awful clips at the expansion bottle end. Can I just use jubilees there when I replace them?
