Hi all,

 

Refurbing the ol' fuel tank and the small vac line was very weak. Upon wire brushing I noticed a small hole, and hey presto it's now off.

 

Am I right in saying this is the vac line for the carbon canister? Can't find much from googling.

 

I'm wondering what the fuel (pun intended) purpose of this is/what it'd affect, and then.. how would I repair it?

 

I can see roughly where it goes, and will be taking the fuel pump off regardless to get better access. Is it easy to route a new pipe in and secure it or will I need to weld it?

 

Cheers!

Simple to repair.

remove pump assembly.

Buy an ally fitting with a push on barb and threaded end with locknut.Drill hole where pipe used to fit. Insert fitting. You will haave enough room to get a socket or cranked spanner

to tighten it.Push flexi pipe on new barb fitting

Job done

 

fitting....may not be correct size....http://www.ebay.co.uk/itm/1-8-NPT-to-5mm-6mm-1-4-PUSH-ON-BARB-TAIL-Hose-Pipe-Fitting-Adapter-Fuel-Oil-/271266095153?hash=item3f28b82031:g:PVcAAOxy3NBSdWOh

That is the fuel evaporation line to CC. FSM pages:

Easy fix then, perfect!

 

What are your thoughts on the carbon canister delete? More hassle that it's worth, or will I thank myself for it further down the line?

I did do a CC delete and then later refitted a smaller one, writeup here:

Would this connect to the pipe inside the tank too, or would you leave that in place and just have the CC fed by this vent?

Personally I would just connect up the new fitting to the CC.. Im not sure what goes on inside the tank?? Maybe someone else does?

What pipe inside the tank?

What pipe inside the tank?

I didnt "think" there was any but you have just confirmed it.:thumbup1:

We are on about the fuel tank here right? I have this inside my tank, with that pipe coming from the now broken pipe on the surface. Sorry for the blurry pictures..

 

 

Took me a minute to work out what I was looking at. Here are the insides of a 2+0 tank. Same gubbins in principle.

I don't (yet) know what the brown plastic box does, but to answer your question the metal pipe inside the tank

should be connected to your repaired CC connection.

 

I assume it'd just be because it's the highest point in the fuel tank to allow vapour in, and the fuel gauge lever will hit it to indicate the tank is full so there will always be some vapour in the tank. But that's just a guess

 

 

I'll see if I can disconnect the pipe from the flexible red tubing in my 2nd blurry pic and make a new one up adding fittings like a brake pipe.

 

Cheers for the help all!
