Carbon Canister problem help

[Paul Smith]

Hi
My carbon canister is filling with fuel then it runs out the breathers?
Never had a canister before.

Help

your piping must be wrong paul, it should only capture vapours

 

[Paul Smith]

Can anyone confirm which pipes connect to which one?

 

[frank]

there,ll be a schematic in the pdf manual paul (or else fire it all into the bin )

That might help a bit mate

Cheers mate. I've compared pics and mine is plumbed in correctly so unsure how I'm filing it with fuel and causing the issue.

The people who have removed these canisters what have you done with the fuel line?

When i binned mine mate it was:

Feed to the fuel filter > fuel rail > injectors

Return from the Fuel rail to the tank

Breather pipe left to vent down the chassis leg

There may have been some vac pipes to the TB to blank off i carnt remember to be honest

 

[Paul Smith]

So I could try leaving the fuel one to vent (disconnected)

So long as the return & main feed are plumbed leaving the vent open should be fine mate, I put a small inline fuel filter in the end of the vent pipe to stop anything going in

 

[Paul Smith]

Yep the other two are plumbed fine. Was thinking if a one way fuel tank valve would do let the air escape but no fuel if it tried again

 

[Madmonkee]

Mmm blanked off my breather, thinking not the best idea...

What happened when you blanked yours? Did you seal it? As I would imagine it needs to Vent

 

[frank]

sounds like the pipes to the tank are mixed up maybe paul ?
there are 3 steel pipes from the tank, the feed, the return and the vent (all the same size) and if your return and vent pipes are mixed up you will probably get fuel backing up the vent

 

[Paul Smith]

I'll double check but I didn't take the pipes off the fuel rail. Mind you the car hasn't been far since I've owned it so it may have had issues long before she joined me lol

I plumbed the vent line into the passenger side chassis leg where the original line was plumbed in from the carbon canister.

Iirc that's where mine goes as well, though i still run the canister just not to the engine.
