Having difficulty acquiring the fuel pipe from the in-tank pump to the in-line pump at the rear of the car. Heritage don’t have the part. The pipe is a reducing pipe from 8 to 6 mm. Any suggestions please? Part number 701201548A

I have previously used an 8mm to 6mm barbed adaptor in brass in the engine bay from 7.8mm internal diameter ethanol resistant fuel pipe to a VW carb using 5.6mm pipe (also in SAE30 R97). 

 

Secured with fuel clips or Jubilee clips.

 

Try Eurocarb or Classic Carbs

... or maybe eBay with less P&P costs but slower.

Thanks. I’ll try that.
