Sister has an EL falcon running on gas which has twice in the last
couple of months backfired blowing apart the air cleaner. Any ideas on
what could be causing it and how to stop it happening. She cannot tell
me what gas system it is. It happened the other day when she went to
start the car. It's an aftermarket system.

Assuming it is an el , the ef was group fire and not so good on gas
usual stuff
plugs leads and converter IF the timing and dizzy are right
it can be useful to cover a hole in the cleaner housing with some flat
coke can taped on so it blows and not the whole thing

The first thing to do is ensure that she's attempting to start the car
without any throttle being used, as that's often asking for trouble.

99% of all gas problems relate to the ignition system, and it's critical
that the car has a good set of ignition leads. Cross firing is the biggest
culprit, which on an engine running petrol generally isn't an issue but when
the entire intake plumbing is full of flammable gas it's a real problem.

The EF/EL range are particularly well suited to lpg use, but that's not to
say they can't have issues. I'd be making sure the leads and coil are in
good nick (if it has a coil) or the Dizzy components are in order if it has
a dizzy.

There weren't any specific problems relating to the EF that prevented them
from running on gas and doing it pretty well. They were a *very* popular cab
in their day and the majority of them ran on lpg without any issues.

She had started the car and put it in gear to take off and applied some
throttle when it backfired

I'll get onto Neil and Bob and order her a set of leads.
