Bosch Pump - Numbered Guide

[cwspellowe]

Hey fellas, need a few pointers on the Bosch conversion as i've never seen either a Bosch or a Lucas running on an engine in any depth. Prizes awarded to those who correctly identify things and tell me what they plug into or where they go.

I've included my guesses, feel free to correct me where i'm wrong

1. Lucas fuel feed banjo, already connected to fuel line on car, Bosch banjo is on the pump
Just remove banjo and put pipe onto the bosch fuel inlet just next to that in the photo

2. Fuel run off line, connects to where?
Connect it to 13 in the other photo (return to tank) you may need a longer bit of leakoff pipe though...

3. Throttle cable arm, which of the two small holes should the cable connect to?
Connect to the one the bolt isnt in, and id slide the whole plastic thing in on the slot on the throttle arm towards the pump all the way.

4. Boost compensator, connects to T-piece on FMIC setup (and presumably the line my boost gauge plumbs into?
Correct

5. Throttle cable guide
Correct, when pump is at idle position, set clip so cable is just tight, but not taking any strain

6.
Fuel out from filter (heading for pump inlet banjo on left side of pump underneath throttle arm)

7. Some kind of vacuum line, goes where?
This is your vacume pump, connect it to the brake master cylinder

8.
This is an air bleed line for the coolant system, there should be a pipe kicking about somewhere in that area with a bleed hole in it that connects to there... same pipe goes to fitting behind pump on the head and also top of the rad / expansion tank


9. Another vacuum line, again goes where?
Normally vac feed for EGR etc...just bung it with a screw.

10. One way breather valve, goes to where on FMIC cars?
Oil breather, either connect back into the air intake (pre turbo) or to a catch tank etc

11.
LDA breather / vent, nothing connects here, just so pressure can equalize under the diaphram

12.
Pump fuel return feed, returns fuel to tank via the other fuel line.

13.
As already said, connects to injector leak off pipes.

14. Stop solenoid? Needs ignition live and earth connected to plug at lower part of pump?
Only needs ignition live, its just a single wire on top the solenoid, god knows why pug routed two cables... The solenoid earths itself to the pump / engine

Hope that helps

Also, how the feck does the inlet pipework get routed? The turbo seems to point straight at the runners on the manifold, the turbo's not been clocked as the oil lines matched up with the block properly. Do people use 180degree bends to bring it back to the N/S of the engine bay?
