Quick question regarding a mechanically governed CAV DPA pump:
Can the pump fuel feed be shut off using the throttle rather than use the mechanical pull to stop cable and/or can a stop solenoid be installed?
The pump is currently fitted to the old hydrovane Perkins 4-108 fitted in the Kubota.
Thanks in advance,
Al

Re: CAV DPA Fuel pump advice
Hi,
Unless someone knows different there is not a stop solenoid available which can be mounted direct to the DPA pump.
I cant remember whether the Transit and Bedford vans with the 108 stopped on the key but it may be possible to rigg a solenoid to opperate the stop cable
Wouldn't it be simpler just to fit a stop cable and pull it

Re: CAV DPA Fuel pump advice
The idle can be set low, enough let the engine stall out, but it really isn't a good idea.
The force to pull the stop on the injector pump isn't very much either, a hobby dc bi polar motor and thread could do the job or even a pull solenoid just to quit the engine, but I'd agree with Fred, a simple pull stop cable would be easier and safer.

Re: CAV DPA Fuel pump advice
Thanks Both,
I've been using the original Hydrovane pull-stop up to now (fitted to the rear bulkhead), but was thinking about simplifying the controls back into the original key start/throttle forward to shut down, Kubota control. I really must get a charge buzzer installed though, it's too easy to shut down and not switch off
The machine is running really well, it's done a significant amount of work for me so far without any major issues. I'm going to make the new exhaust system and bonnet when I get a chance, given the good weather and long days the machine hasnt had much downtime though.
Cheers
