where should this vacuum hose connect to ?

[alze]

Hello fellow bongonauts,

I'm trying to get my bongo running reliably again as it stalls as splutters, when revved doesnt go above about 1500 rpm.
Going thru the usual service stuff first, have changed the fuel filter, cleaned the banjo (found it was very blocked!!) and tomorrow i'll be doing the glow plugs (waiting long socket set to get glow-plug bus-bar bolts off).

One thing I have found which may be causing the issue of the bongo not running properly is this errant hose coming from the vacuum pipe and solenoids. I've looked at the schematic on lush projects, but for the life of me can't see where it should go when I look at my own bongo.

I've uploaded all the photos so far to my google photos https://photos.app.goo.gl/JTzEmn8T5KWe54Tc6 with the unknown pipe being the one with my hand and what i think is a snapped off connector to somethng to what is a filter.
In https://lushprojects.com/bongopartsmk2/ ... f02.html#7 I think its the hose from solenoid 18741A and pipe 93-5104.

Appreciate any help, really hoping i can fix this myself and get the Bongo back on the road !
