Peel gauge

[jordo84]

Broke my old gauge/switch and my local gas man ordered me 6 pin peel one, now my old girl will only run on petrol and will only run for a couple of seconds on LPG, my old switch had only five pins?

If the switch (which you didn't identify by part number) has a RPM input then one of the wires is connected wrong. There should be a connector that is wired to the ignition coil negative so the switch will allow gas to flow only when the engine is actually firing and stops after 1-2 secs if the ignition goes off.

Look here for guidance.
