The PROTEC fuel pipe arrived from Demon tweeks
one end 8mm ID (fuel pump outlet spigot)
one end 9.5mm ID (spigot on the outlet plate)
no instructions
, some plastic shrinks when heated , some stretch
It required heating to get the pipe to stretch onto the spigots
A youtube video showed some suicidal maniac heating the pipe with an electric hot air gun
(sparks from the motor brushes and a glowing heating element
)
being an in petrol tank connection I opted NOT to use that method or a flame
i heated the ends gently with boiling water and they slid on .
I also added small (10-12mm) fuel line clamps (being a 4 Bar pump)

also worthy of note ....
As we found out, there are 2 sizes of fuel pump ,
the pipe above fits the BOSCH 815038 9196213 pump as fitted to my 53 plate facelift 2.6 SALOON
