Is fuel cap vent necessary?
With turbo fuel injected engine? My new one with the funnel does not appear vented. Will this cause a problem? Thank you!

I'd've thought it'd only be needed if you have no other fuel breathers.

Yep, you just need to let the air in faster than the fuel comes out...
just a vent pipe on the tank somewhere (some use a special roll over valve to stop fuel leaking, or just a U of pipe so the fuel can't leak out
if you roll)..
In manufactured cars they use activated charcoal, and pull a slight vacuum on the tank to stop venting of petrol vapors (not required in locost)...

I'm sorry, but I have no idea what you are talking about, so I gather I need another fuel cap, and I've just wasted 70 pounds plus
shipping. I can't just ADD A VENT to an existing tank full of fuel. Thanks for the replies though.
Why can't I just bolt parts on, get it inspected, and go driving? Why? Really?

Can you not remove the filler neck and add a bit of steel pipe with a breather in it into that?

Sorry, again, but I don't understand. I don't weld either, by the way.
Do you mean drilling a hole in the funnel?

Drill a couple of holes in the cap out of sight?
Should breathe enough to do the job

Now that I can probably do!! Thanks! I have a few more odd jobs to do on it before shipping it out to BC for provincial inspection there. Need to
decide if i'm ditching my dodgy gauges for a digidash too. Making the new dash should be easy.
update: upon checking the new cap, this does not look possible. Any other ideas???
