Hi there i am hoping to find out some information on how to fit a baileys dv26 dump valve. I have been advised to leave the oe valve alone and not mess with it. But i have also been told if i am to fit a dump valve i should fit a T piece into the fuel pressure pipe is this correct?? Ifso could someone please highlight the pipe on a picture. Thanks if you can help. I have just joined this site and it looks like it could be full of very useful info.
