it does, though you can bypass the T piece and run directly onto the vacuum pump and blank the intake port.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

i have a feeling something has been lost to google translate here?if you leave an open hole on your intake manifold....your engine will stall. the best option is to source that t peice if you want things standard. id suggest getting a blanking pate for removing your vacuum pump (spoox shop  ). and fitting a simple one way brake valve inbetween your inlet manifold vacuum line and the brake booster line.or failing that welshpugs option of just plumbing the booster line into the vac pump is viable, but i would still add a one way brake valve in the line. if for whatever reason you remove the brake booster line from the brass nipple on the inlet manifold, that open hole in the brass part will make the engine stall.....this is what you need to blank/block/cover. if you introduce a hole to the manifold by removing the vacum line and it doesnt want to stall, there is a problem.....and if you cover the hole and it stalls then.....you also have a problem. ________________________________________ the world is changed by people in sheds |
