Help with some pipes, pictures added

[boustie]

Trying to figure some vac pipes out, can anyone advise if i do the following this would be OK. Half the stuff was missing off this engine before I rebuilt it.

If i run pipes A to dump valve and turbo actuator and B to boost gauges see below:



Not sure what goes to A and B, also there is a small vac connection near C on the bottom of the carb.



Am i correct in joining the carb lobster and the bottom pipe as shown, also the pipe circled has always been blocked off, is this correct.
Stupid question is X fuel inlet?.



Any replies greatly appreciated.

Hold on matey you don't want to do that.



Pic 1
The dump valve should be T into the AEI vacum line that goes to the manifold just below were the carb bolts down to also T your Boost gauge into this line aswell as it will you vascum reading and a more accurate boost reading to what the engine is getting, plumbing the boost gauge into B is fine but it will give you carb top boost you will loose abour 4-5 psi through the carb best sticking boos gauge into AEI vacum line.

A - Goes straight to the front port on the actuator.

B - then loops down to the carb base port

or you could do the cup mod and loop A & B together and then the front port of actuator will go to carb base which is B in your Pic 2


Pic 2
A - overflow pipe for carb if gasket splits this goes to a long pipe that just hangs down front of engine away from anything very hot
B - connects to carb top in your 1st pic which will be B or do the cup mod and loop A&B in your 1st pic together and this will then go front port on actuator,
C- is your AEI vacum line you T your D/V into this and your boost gauge

the one with the big X is the fuel supply to carb

the other port below that is the Accelerator pump gasket this connects to the carb lobster top

the part you have circled shiould have the carb mixture screw in place

First picture

That is fine to run it like that, doesn't matter which port it comes out from A or B

Second Picture

A is the fuel overflow pipe which runs done the front of the engine and just rest it through the hole by the oil pressure unit
B is carb base which most people use for the turbo actuator
And C use for the AEI to measure the boost

Third Picture

X is the fuel input
The circled section on the carb is the mixture screw

OK thanks for that, my actuator only has one vac port should i use a pipe from B in pic 2.

As you say loop A&B in pic 1 together and then just go from Pipe B in your 2nd pic to the actuator front port if dual port if single just to that single port

or loop Pic 1 B to pic 2 B and the use Pic1 A to the actuator

oh and which one to fuel pressure reg ?

[boustie]

Can i mount my fuel pressure reg anywhere ?. Plenty space on the drivers side under bonnet ??
