Replacing fuel lines on old VWs seems to be one of those popular things to do at the moment.
The composition of our fuel has changed and we keep hearing all those horror stories on forums about vans going up in smoke due to perished fuel lines.
The thing is, it's usually only the end rubber sections that fail however what usually happens is that some do-gooder has gone and replaced the lot with rubber, front to rear! It's a common situation and why we have started manufacturing replacement fuel feed and return pipes to be sold as a complete item and to put the van back to how it should be.
The hard plastic fuel lines are made from a material called "Polyamide" and are very robust, not only chemically but they also resist abrasion very well if clipped into place as they should be.
The polyamide tube we sell is manufactured to DIN 73378.
Polyamide tube is really easy to work with so we thought we would put a quick page together to help you understand some of the products a little better and to give a little more confidence in working with this robust, durable and cost effective fuel line.
When it comes to sizes you need quite a tight fit, for a 8mm tail such as the output from a fuel tank you need 7,3mm fuel hose, the same goes for 8mm OD polyamide, 7,3mm ID fuel hose.
For 6mm tails or polyamide tube you use 5.5mm ID hose.
Oetiker clips can be found here. The correct sizes are in related products on the hose pages though.
Closing tool for Oetiker and CV boots but you can use normal pincers.
Or, if you want to buy it already done then we have a couple of kits already made.
To fasten the pipes down the length of the chassis...
The change hose size.
For making removable connections to the fuel tank, filters etc..
Hopefully that should give you a little insight into this great product and help you save some money by not ditching the PA and swapping the lot for rubber!
