Just read this and would like to ask how many of the people saying that aeroquip pipes are MOT failure are actually MOT nominated testers???

I am and have been for 5 years, It's Bollocks!!! You can only fail a car if it meets the VOSA "reason for rejection" and the book only says as follows:

Method of Inspection
Running the engine
This inspection is to be carried out both with and without the engine running.
1. Check the following for leaks or insecurity:
a. fuel tank Reason for rejection a. fuel leaking
b. all visible fuel hoses, pipes and unions Reason for rejection b. a fuel system component insecure.
c. all visible fuel components

Opening the luggage compartment
It may be necessary to open the luggage compartment to carry out a full inspection of the fuel system.
2. Check fuel tank cap for positive fit and condition of sealing washer and flange.
Reason for rejection
a. fuel cap does not fasten sercurely- by a positive means, or- such that pressure is not maintained on the sealing arangement
b. fuel cap sealing washer torn, deteriorated or missing, or a mounting flange/sealing method defective such that the leakage of fuel is possible
Locking fuel caps
If access cannot be gained to the fuel cap because it is locked and the key is not readily available or because it cannot be opened for some other reason see heading 2 of the introduction of this manual.

So IMO Dan fire away son with your Aeroquip pipes!
