Newby- fuel questions
I am trying to plan my fuel system and have a few questions. My fuel rail has three lines. One inlet, one return, and I'm assuming the other is for
the charcoal canister For venting. I do not have a charcoal canister so I was wondering is there any other option for this line? Also I do not plan
on running a surge tank, I am assuming these are more needed for off road, is my thinking correct?

Hi
For rego purposes you will need a charcoal canister.
You will most likely need a surge tank, depending on the model of VW you have, there are various ways to go about this. What sort of VW are you
fitting the motor to and what sort of motor is it?

If you're in NSW and I would guess other states are the same you only need a charcoal canister if the car was originally fitted with one and it's
only bugs from early 75 onwards that did.
I installed the Subaru one in mine but the engineer told me I didn't need, as my bug doesn't have the ADR # on the compliance plate calling for
it.
That was over 2 years ago but I doubt the rule's changed.
You can leave it open and just cap off the feed on the throttle body.
I chopped all the canister hard line out of mine, looks much neater.
If you're using stock ECU you'll need to leave the Purge control valve in place and wired up just with no hoses on it otherwise the computer will
spack out and throw error codes at you.
That's all I've done with mine.

Hi Joel
I was lead to believe that you needed to retain all pollution controls from the donor vehicle, the RTA looked at this on my car.
As far as surge tanks go I just read that your doing this conversion to buggy, why not do a drop down extension to your fuel tank on the passengers
side and then take the fuel feed from there and then you would gain some fuel capacity as well.

I'm putting it on a buggy project that is already registered. The engine is an ej25. Cap says 2003. Also anyone know the fuel line sizes to use in
standard (damn American system)? According to my conversion 8mm metric is about 3/8" standard

Hi
You will still need to get it engineered even if it has rego.
8 mm is closer 5/16.

Thank you for the reply. I also had some questions regarding the fuel hose/ line. I know that fuel injection requires way more pressure that vw
engines. Is it still suitable to run a hard fuel line to a fuel hose with a hose clamp as you would in a vw? Also, I noticed that on the VWKD site
there was a guy that made provisions for a retun line in his gas tank, and he use solder to adhere the fitting as opposed to welding. Is this a
adequite practice? This seems like a great option for me, just want to make sure that people have had success with it before-hand. Thanks for the
help. |

Gday Steve,
An Engineer playing it on the safe side may make you fit one.
Mine told me I can install it if I like but as my car didn't have a factory one and there isn't an ADR code on the compliance plate calling for it I
didn't have to fit one.
I just had to meet the relevant rules that were on my compliance plate affected by the conversion which for a late 74 bug was ADR27 and ADR28
Streetbuggy, Hoses with clamps on the end of rigid line is fine (that's all the factory subi ones are) but it would pay to put some sort of rib/flare
on the end for the hose clamp to bare down on.

I am shopping for fuel line. The fuel line here is measured by O.D. apparently. Would it be advisable to get 5/16" O.d line or go up a size to
3/8" to make sure that the I.D is big enough?

I have some information on my buggy build that may be useful to you on this forum. I think page 3 or 4 talks about the fuel lines I used.
