Fuel Hose Kits Suitable for Aircooled Engines. Splitscreens, Bays, Beetles and T25. 

VW Aircooled works offers a large range of fuel hose kits, produced specifically for the VW Aircooled engines, both campervan and beetles. Each kit is made using the exact same high quality components that we regularly use at our workshop.

We make up our kits in house so if you do require a specific configuration such as all hard line or for a sports engine please feel free to contact us and we will go through each inquiry personally.

100% Bio-fuel 'Fit and Forget' Fuel Hose.

All the fuel hose used with in our 100% Bio-fuel kits are suitable for use with up to 100% ethanol. The fuel hose will not break crack or split due to the presence of bio-fuel within the petrol. These are non rubber and have a life expectancy of 25 years when correctly maintained, hence the ' Fit and Forget' name.

This fuel line is used today by Volkswagen in its new vehicles, and a lot of high end sports cars, the advantage is that even during storage there will be no deterioration of the fuel hose due to ethanol. 

The internal diameter of each fuel hose is designed to give the correct amount of grip force when connected, this limits the potential of leaks and gives a safe and tight fit to each connection.  The fuel clips we supply are good quality band clips though slightly fiddly we find they hold a lot better and exert a good even firm pressure when connected doing a much safer and better job than some other clips we have tested.

All the kits detailed below are available to purchase through our web shop.
The price also includes delivery to mainland UK. For any other address please contact us before purchase.

SAE J30 R9 Fuel Hose Kits suitable for E10 petrol (modern petrol)

Unlike the 'fit and forget' fuel hose this fuel hose contains rubber so will degrade over time in the presence of ethanol. However unlike the braided fuel hose line this SAE J30 R9 specification hose is ethanol resistant and is compatible with E10 petrol.

It has a normal shelf life of about 5 years, the duration of a modern car warranty.  However this is substantially decreased if the vehicle is left stood for a long period of storage, so in practice in a VW campervan it would normally only last for a couple of years depending upon how you use the vehicle.  However this is significantly better than the braided hose which degrades in months in the presence of E10 petrol.

Accessory Available For Fuel Hose Changing . 

Hard Line Kunifer pipe

Hard kunifer lines are designed to go through the tinware instead of using fuel hose this  prevents the hose being chaffed and rubbed which can shorted the life span of the fuel hose and cause crack and leaks.  This is also available for both 6mm and 8mm engine set up.














6mm shaped Hard line kunifer pipe = £7.50

8mm Shaped Hard line kunifer pipe = £10.00

It is also possible to design your own fuel hose route using the hard line kunifer and only small connecting sections of fuel hose. Please contact by email with pictures of your engine set up and we can discuss routing and measurements on a case by case basis.


Ethanol Resistant Fuel Tank Treatment Kit.- £45.00

This two part kit is designed to clean and remove rust from inside your fuel tank. Once clean the tank is fully coated with an ethanol resistant coat. The fuel tanks used in VW's are metal so are liable to rust over time. The presence of biofuel in fuel is increasing the rate of degradation.

This kit removes the rust, and coats the tank with an ethanol resistant layer.

Ethanol Resistant Fuel filler Hose. - Early Bay.

The fuel filler hose is designed to connect the fuel tank opening to the fuel filler neck. The old braided hose is likely to be 30 years old, and though it only has limited contact with petrol and petrol vapors, this still deteriorates over time.

VW Aircooled works offers a Ethanol resistant fuel filler hose. This hose is the correct diameter and size to fit on an early bay as a direct replacement.


The Kit includes:  

0.18m - 57mm diameter fuel filler hose
2 x Large fuel clips

If your fuel tank is out then it is probably worth considering treating your fuel tank to remove rust and seal it with an ethanol resistant coat.









Fuel Clips

A pack of 14 fuel clips -£5.00


Fuel Filters

Replacement plastic fuel filter - £2.00


Top tip -  When locating the fuel filter make sure it is away from the engine.
