Where do the pipes off the FRST Amal valve go?
just checking if mine are right after i have put it back together
The pipe on the right side fits to a t-piece which splits off and goes to the actuator and turbo
and the pipe on the left goes to a nipple on my air filter pipe...
All help appreciated

I have to be very careful here as I like Martin and respect a lot of what he does but as a FRST amal only has 2 ports that is not quite correct 
I have to admit that I had to remind myself how the FRST one works .
All the Amal valve does on a FRST is switch from open to closed when the boost pressure gets to the preset limit , it is not like a cosworth one that switches from atmosphere to can at that point .
Pipe from snail housing has T piece in , one goes to actuator , the other goes up to the top port of the Amal valve with the wiring on the backward side of the valve , the bottom port goes to the inlet pipe .
Hope that explains it

Its ok Martin , I did the same some time ago and I have a FRST in the garage , but used to work on Cosworths a lot so knew exactly why you did what you did , will have to pop down and show you my FRST lol
Wondered what I had missed to get Stu to post then scrolled down a bit further to see he had done the same as me and missed my post , as I had not seen his second one , at least we agree Stu
