Right I wanted a dump valve on my astra h sri turbo but could not find a guide. I have never fitted one before and must say was pretty easy! hopefully someone will find this useful.
you will need:
1 x dump valve - I went for a collins twin piston
1 x dump valve take off pipe - http://www.courtenaysport.co.uk/inde...&productId=416
1 x plastic t-piece
1 x 2m 3mm vacuum hose
1 x scissors
1 x 7mm socket
4 x cable ties
1 x matching air intake pipe.
tight here's me stuff:
this is my dirty engine before I started:
undo the jubilee clips and remove the circled pipe
once removed locate the Fuel Pressure Regulator (FPR) which is to the back left of the engine and pull off the vacuum hose
cut approx 2" of the new vacuum hose and place on the top of the t-piece. then connect the original vac pipe to the bottom of the t-piece. finally connect the rest of the new hose to the side of the t-piece and run down the bulk head back towards the battery. should look like this:
connect the other end of the vac hose to the nipple of the dump valve and then place the dump valve into the take off hose and then connect the new take off hose and tighten the jubilee clips
bit of a tight squeeze
if you have bought a air intake also simply undo the jubilees and swap the pipes.
when all connected strike her up and check for leaks. when happy tidy the vac hose up and go for a heavy footed drive and enjoy your work i used cable ties to tidy my vac hose.
was pretty simple and took about 30 mins of my time also now realise I need to clean my engine bay!
this will need moving to the how to section but don't know how to do that!
