318IS M42 fuel breather pipe, filter thingy etc HELP

[mrfuzzyfelts]

Right i have the pipe which goes from the rear (near tank) to the carbon filter thingy under the bonnet. and 1 pipe from this out to vent and 1 to the THROTTLE BODY.

Ive removed it all, so should i block the pipe going in(or out) of the throttle body or leave it open

[stuartgallafant]

you're not really giving us a lot to go on here mate...

[mrfuzzyfelts]

On the throttle body, there is a pipe going to the carbon filter, do i block it up or put a filter on it?

[stuartgallafant]

does it already have a carbon filter?

if so, then put it on. mine doesnt, so i dont even think i have the pipe?!

[mrfuzzyfelts]

got a pic of ur engine / throttle body then??

If urs has no outlet, ill block mine!

[stuartgallafant]

not on me mate

and my car is about 80miles away

Does your car have a cat?

[mrfuzzyfelts]

yep

[Chris-W]

Best replace the carbon filter and re-connect the pipes / wires then!

[mrfuzzyfelts]

Why do you say that?

Think ill have problems if i dont?

[stuartgallafant]

Why do you say that?

chris is saying that for the fun of it...



He's giving you advice... in my experience, his advice second to none, and if i were you, i would take it unquestionably...

On a non-cat car, the fuel vent pipe has rubber hose on the end that is just left open, I have seen it tucked into the bracket on the side of the passenger side strut tower.

If your car has a catalytic convertor, then you should have a carbon canister. As Chris says, best to replace canister as it is supposed to be part of the system. It was fitted by BMW for a reason.

Do not block it off whatever you do!
You fuel tank will not be able to breath and will apparently suck itself inside out

I was gonna block the bit on the throttle body not the pipe

all done now,

Blocked the throttle body and vented the other bit out the back!

Cool no implosion then

Indeed, any blockage of the fuel vent pipe is dangerous. The idiot who replaced the vent pipe on my car kinked the flexible section of pipe at the fuel tank end and caused my car to cut out several times in traffic almost causing an accident. Manged to get the car parked and rang the garage, and they asked me to bring it back across town myself instead of coming to me! Eventually got it back to the garage and they diagnosed the f*ckup. Didn't really apologise, which really pissed me off given the severity of the situation. Needless to say, he doesn't get my custom anymore.

I guess on non-cat cars, when the end of the rubber pipe section in the engine bay is tucked downwards into the bracket at the side of the strut tower, it means it isn't exposed for some foreign item to enter it and block the pipe.

thanks Kevin ,just doing a bit of preMOT checking and wondered why I had 3 fuel lines with 1 going into the chassis rail!even more suprise when I pulled the pipe and it wasn't connected to anything.I'll tuck it back then

Be interesting to measure your fuel tank capacity now!
