lpg fuel gauge problem

[fullymetal]

I have a problem with my fuel gauge on my vs comm.

It works fine on petrol but when I switch to lpg the gauge won't move of red and the low fuel light and sound come on.

It's factory fitted so the gauge for lpg is the same as petrol and it worked fine up until today.

Any ideas on what the problem might be?

Aside from, got any gas in the tank? maybe the sender has come lose. have a poke around and see what you can see

[fullymetal]

Yeah the tank is full

im guessing that the sensor would go off presure? maybe the pressure sensor is broken

[fullymetal]

How would I check that? and how much to fix it?

For some reason it just started working again this morning. I hate when stuff like that happens

Just a quick note here. I have found with my guage, if I flick it to LPG whilst in motion on petrol, the guage won't show up for LPG and will still show the petrol. Maybe that is your problem too?

If it really bothers you, I would suggest maybe getting a LPG joint to look at the dual fuel control unit and its wiring. Could be a lose wire or solder joint

With the factory fitted lpg you can't change between lpg and petrol unless your stationary.

You just gotta be in neutral
