I've put a hose clip on too which will hopefully stop it squirting off.
I would certainly go along with this as I've learnt, to my great expense.
Thought that I would save myself some money and fit the pump myself. Followed the instructions to the latter. All seemed fine after some long periods of road testing.
Took the car up to Courteny's on Friday for the final mapping. On the last speed run on the Dyno, the convoluted pipe from the fuel pump to the upper part of the housing, blew off. Result is that now on pin 29 of the ECU we have a positive voltage, rather than a switch to earth which would activate the K16 relay which supplies power to the fuell pump and injectors.
The result was another return trip from Courteneys with the car on my trailer, and it now looks like a new ECU, or at least having it checked out by a speclist company to see if has been damaged...And this is all because I did not put a worm drive clip on the fuel pipe on either end of the pump connections.
To be fair to John and Mark at Courteneys they made a sterling effort to track the problem, putting in some extra hours to fault find.
So make sure that a worm drive clip is installed at both ends of the uprated pump!
