Hi
Trying to track down the correct steel fuel line that runs from the front shroud by the heater box on a upright twinport motor around to the fuel pump which I believe is 6mm od.Over here in New Zealand I can only find 1/4 inch (6.3mm od ) which does not fit the ferrule at the pump.I know I can jerry something up but any leads on either a prebent 6mm od pipe or where I could buy 6mm od pipe off the roll would be appreciated

I have no answer in regards to your fuel line question...
But I have major envy for your workshop! It's spacious, clean and organized, all features that mine lacks. Crying or Very sad

Yep, nice shop.

As far as the steel line goes I think it depends on what fuel pump you have. I have a Pierburg and it's pipe is solid from the pump inlet, through the front firewall tin, to the left side heaterbox where a rubber fuel hose is connected. Most type 1 fuel pumps aren't like this. They have a piece of rubber hose between a steel pipe and the pump inlet. You can buy those at several places I think.

Thanks for the shop comments , its normally a scene of kaos especially when my son has been in there.Below is a pic of the prebent pipe 1/4 inch 6.3mm pipe which I got off a vw shop here over in NZ.I could have rebent it to fit if it was the right diameter to fit into the pierburg pump. Tried Wolfsburg West but out of stock so have ordered from England a 2.5 metre of 6mm od cupro nickel brake line.Hoping it will do the trick

The fuel hose size is actually 5.5mm

Hmmm....., removing .3mm can't be that hard even if you don't have a lathe, a few minutes with a file as it spins in a drill would do it. Or consider squishing it down a little with a flaring tool clamp, food for thought as you await that stuff from the UK.

I had thought about taking a skim off the 1/4 pipe so the olive would fit and pipe would fit into the recess in the pierburg pump but the clencer for me is I found the Cordan 5.6mm fuel line too hard to push on even 10mm on to the 1/4 inch pipre while it was siitting in my lap let alone trying to push it on when the motor i in.I will give this cupro nickel line a go, it cost $30 for 2.5m so should be able to make up 3 or 4 lines.Will report back whats its like

When on 8th August 2018, I last checked the currency exchange rate, it was NZ$1 = £0•523318, so unless it was drastically different when you bought your Saville’s 6 mm cupro-nickel brake tubing prior to 24th March 2018, NZ$30 for a 2•5 metre length seems rather expensive unless it also included postage & packing from England to New Zealand.

www.saville-products.com/

A few days ago, I checked on-line in Great Britain, for a source of Saville’s 6 mm cupro-nickel brake tubing. A 25 feet (i.e. 7•62 metres) length was available from Vintage Warehouse 65 for £25•95 (circa NZ$49•59), which translates as about NZ$16•27 for a 2•5 metre length.

Saville’s 6 mm cupro-nickel brake tubing also seems to be available in 7•5 metre lengths from UKB4C, listed at £29•99.

In Great Britain, cupro-nickel (i.e. Kunifer-10 | 90% copper & 10% nickel) tubing for automotive applications, seems to be most commonly available in in 3/16, 1/4, 5/16 & 3/8 inch (i.e. 4•76 mm, 6•35 mm, 7•94 mm & 9•53 mm) O.D. x 25 feet lengths. There do seem to be a few suppliers of 6 mm O.D. cupro-nickel tubing, but it’s not so widely available. Most industrial suppliers of metric cupro-nickel tubing, list tubing in O.D. sizes of 10 mm and larger.

The mechanical fuel pumps on all the VW Type 1 style engines (with either dynamos or alternators) that I have seen in Great Britain, have had both inlet & outlet fittings for push-on braided neoprene hose; including the fuel pump on the factory-fitted AD-Series VW 1600 Type 2, twin-port engine, in my British Specification, 1973 model-year (manufactured in circa late-August or early-September 1972) VW 1600 Type 2 Westfalia Continental motor-caravan.

When in 1989, I converted my 1973 model-year VW 1600 Type 2’s VW Type 1 style engine from dynamo to alternator, I reduced by 6 mm the thickness of the spacer portion, of the phenolic spacer cum guide tube, for the original pushrod (similarly shortened by 6 mm) and “dynamo-type” fuel pump, so that I could reuse the upright “dynamo-type” fuel pump, rather than substitute a canted “alternator-type” fuel pump.

I used about one and a half 3/16 inch (i.e. 4•76 mm) O.D. x 25 feet lengths of Kunifer-10 cupro-nickel brake tubing during Wnter 1988/89 on my 1973 VW "1600" Type 2 when I retro-fitted ATE (i.e. Alfred Teves) twin remote-acting vacuum brake servo units and replaced the remainder of the factory-fitted brake tubing, as a long-term precaution against corrosion.
