Fuel pump isnt working on the 110 csw v8 I bought recently, not been an
issue because it starts ok on the lpg but need to get it sorted before I
find myself somewhere with no lpg.

Question is - is there somewher where there is a join in the loom so that I
can check that this is the pump and not a power supply problem before I go
to the trouble of dropping the tank.

Thanks

If it's the same as mine there's a plug and socket on the LHS just on the
top of the chassis about level with the front end of the tank.

Thanks Bob.
Exactly where you said it was, but tucked out of sight behind the chassis.
Got power so guess it is the pump. Probably burnt itself out when the
previous owners stopped putting any petrol in.

Sounds likely if it was left powered up when switched to LPG. There is
a bullet connector on the engine side of the bulkhead that supplies
power, I keep meaning to put a simple relay in there and have it
deactivated when LPG solenoid is powered.

Nice idea. If you have to pay full / new price for a new pump, you'll
certainly be doing that!

If you have petrol in the tank, leaving the pump on shouldn't hurt it - the
pump is designed to run continuously, after all. Running it dry for any
length of time is probably a bad idea.

I thought about switching it off but decided against it - with the pump
running, switching back to petrol is pretty much instant, if you off the
pump I imagine the pressure will slowly disappear from the high-pressure
side of the petrol system, and then when you change over it will take time
to re-pressurise. Sometimes, when you suddenly find you're out of gas for
accelerating, you don't want a delay while the petrol makes up it's mind to
appear.

This assumes that you've got the petrol system being disabled by
interrupting the electrical supply to the injectors, of course.

Good excuse, as mine can be a pig to make a second start from hot on
gas I like petrol to be readily available. The other thing I haven't
done is lift the dashpot pistons.

As I implied, this has good ole SUs

My system "Bigas" has a delay in the change over from petrol to gas of 30
seconds to allow the gas to get to where it's needed. I wonder if it would
do the same in reverse for the petrol. At present it's pretty instantaneous.
Multitude of tweaks were available via the PC. Tis an injection system.
