If the hoses show no sign of cracking or deterioration then re-use them. I would always put a jubilee clip round the ends to secure them. The pipe from the tank to the pump is under slight negative pressure (the pump is sucking here), whereas the feed from the pump to the carbs is under slight positive pressure (the pump is blowing at this side). You don't want fuel hoses coming off and fuel being released in the engine bay.

You need new hoses because the old ones are unsuitable for use with today's petrol.


I am not familiar with the 1500 but would imagine something from the following will be okay

It is prudent to replace the steel pipework from the tank the pump,
I use 8mm kunifer for this.

The classic VW people have looked extensively at fuel hose and ethanol containing fuel. Here's all you need to know:

I can't speak for any specific supplier, but be aware that not everyone selling fuel hose is supplying the ethanol resistant variety. R6 hose, still freely available, is not suitable.

These days I will only use Gates Barricade hose on my classic cars, I've had so much bad experience with so called "R6 and R9" hose that unless it's branded and from a known good source I won't touch it.

I went to the trouble of importing a small role of 1/4" bore Gates hose from the USA a few years ago - well worth the price.

Generally r6/r9 should be advertised as such. In theory if the hose actually meets r9 standard it should be fine, but in practice I've seen a lot of stuff marked r9 that just crumbles to pieces in a matter of around 6 months.
I guess the best solution is to speak to the supplier?

For reference I bought: "Gates 27313 1/4 x 25" (Not available on amazon at the moment which is where I got it from)

For the small cost of the hose it would be well worth replacing them with some decent quality new ones. Lots of the new hoses can deteriorate quite quickly with modern fuels and cause a leak/breakdown. It may look OK but can fail soon afterwards.
Don't bother asking me how I know that!
