Hi Guys,

Just in the middle of converting my 93 classic into top feed parallel fuel rails, but i have a query regarding the carbon canister plumbing.....

Seems there is a feed from the top of the throttle body, that goes into a metal pipe under the inlet manifold, then into the carbon canister, then from the carbon canister under the manifold, into one of the three fuel pipes?

Is the above correct, and what can you do to remove this bit, does there need to be three fuel pipes? Or do I just Tee the two return pipes and plumb that into the the FPR?

 

its just a vent to keep to petrol smell out of the car, no fuel runs down the 3rd line. it draws the vapour to the canister via the throttle boddie.

 

So should i just wack a one way valve on it or leave it vented to air or what?

 

On mine I used the one way valve from canister and stuck it on the end and left pipe just under bulk head.

 

Spot on, was thinking about doing that, but wasn't sure if that would work... But I'll shorten the pipe and bung the valve on the end of it.

Just gotta figure out which one of the three pipes it was now

 

top
middle
or bottom

im pretty sure it the middle one but i could be wrong. i used vac pipe to plum it all back in to the canister, all is good

 

I removed the whole canister from mine....

 

let me know how you get on i may remove mine

 

Looks better with canister out

 

any vapour smell

 

any one got a diagram, i want to run my 97 uk with the parallel rail< i have a fpr on it already, chhers guys

 

If ur talkin about charcoal filter on left front
Of car ?( Black circular thingie ) I'd b intrested 2 no 2 ! Previous car a mate took it out in about 5 min, wondered how it was done,, aparently there is a valve under the inlet manifold .. But still don't quite understand ( 95wrx)
