Hi all

Hope you are all having a good long weekend.

Just a quick question, i have ordered a modified carb spacer to plumb the dump valve actuator into, but i cant really be bothered to remove the carb again if its not necessary, so is it ok to plumb the dump valve into the servo pipe?

comes out the inlet manifold here:





Would it be ok to 'T' it into the rubber hose going to the servo:





Or would it be better to fit the modified carb spacer?


Thanks all!

ive always used the servo pipe, involves less gaskets to go wrong and more carb clearance with the bulkhead too.

i shall use that servo pipe then, was just curious as according to the haynes book of lies it has a one way valve or something coming out of the inlet manifold, so wanted to make sure that wouldnt effect the dump valve. I have only just had the carb off so really didnt fancy taking off again if its not necessary.

cheers for the info

does yours not have that one way valve bolted in there which goes off to the air filter?

I drilled a hole in the side of the servo pipe banjo and brazed in a bit of stainless pipe to connect the dump valve hose to.

As long as you are the manifold side of the vale it'll make no difference.

cheers guys, i have a t'piece that came in the fitting kit which is the size of the servo pipe, but if i get keen ile just pull the carb off and use the modded spacer. Started fitting that maniflow system earlier "metro turbo" you have to modify the downpipe to turbo clamp slightly by grinding down the edges of the clamp as it is to small for the bigger pipe, but fits ok after that. Tightening the elbow to downpipe clamp on the drive in the snow wasnt overly pleasant mind!
