Removed a 6BT from a bus,'90 model.In the the fuel system after the filter and contacted to the VE pump is a small fuel line with some kind of a electric solenoid working it somehow.There is a small line via a tiny banjo fitting buddied up atop the banjo bolt leaving the stock fuel filter housing (actually the under side of the intake). It goes to the VE pump right inboard the fuel line, on the block side of the pump, with a solenoid inbetween. There was a electricial wire attached to one end of the solenoid. Since the engine is remved from the vechile I have no easy way of figuring it out.Really would like to be able to do away with it since the whole fuel system is being upgraded to 1/2 inch. Sorry about being so long winded.Thanks in advance.Also posted on the Bombers site.
Look again at the VE pump and the soleniod on the outboard bottm of the pump is not there.This must be a remote soleniod for what ever that does.Isn't it something for cold starts???

 

A picture would help. I am assuming its someones version of a remote Fuel shutoff solenoid.

 

Sounds like you are looking at the KSB valve, down near the front bottom of the pump?
It advances the pump timing during cold starts.

Sorry my stupid.It is the KSB. Never saw one located remote. Actually located the about the middle of the intake. Single bolt mounting it to the intake,plumbed into the fuel system via banjo bolt exiting the fuel filter. Sorry about all the confusion,never noticed one remote before. Now can it be disabled without any harm to the VE pump?? Thank again everyone.

 

Could you post some pictures if it?

Now you have got me wondering, there should be no direct connection between the KSB and the intake manifold except for an electric air temp sensor, the KSB only applies fuel to an internal piston to advance the timing, everything is done inside the pump body.

Being from on a bus, maybe it is part of a cold start either injection system, or some kind of a water/meth system.

Also note that non-intercooled and intercooled pumps both have KSB valves and although the purpose is the same, the function is entirely opposite.

BTW are you sure it is a Bosch VE and not a Lucas CAV pump?

Trying to get help from someone to post pic's.In the mean time.The valve is only mounted on the intake. There is no port or any type of connection.Was just explaining where the fixture is located.

 

Does the engine have a grid heater? It could be a cold-start device, if there is a line into the manifold. Old Ford tractors used a set-up that drained a little fuel from the return line into the manifold, onto an element that lit the fuel, to heat the manifold.
