Hi Guys,

I suspect this problem may be a well worn one on this forum but I have delved back through & not been able to find anything relevant thus far.
I have an EF on LPG which I just bought at an auction. On inspecting bits & pieces to get ready for a RWC I noticed that the air inlet duct has a large hole blown in the top of it.
Shopping around the wreckers (unsuccessfully thus far !) a few guys have told me that this is a common problem with EFI fords caused by LPG backfiring & blowing the plastic to bits.
If this is a fairly common problem I suspect there would be a few fixes out there somewhere especially given the number of taxis running the same setup.
If anyone can point me in the right direction before I go spending my hard earned on more plastic to blow apart I would appreciate it.

Rodent the best thing is put new plugs and plug leads on
I service taxi's and limo's and found eagle leads to be the best for lpg
Also make sure you do not use acclerator pedal when u start the motor.

Yes plugs and leads,a missfire will cause a backfire so change your plugs on a regular basis and you shouldn't have to many problems.If you think this is a problem on Fords talk to some commodore owners even bigger problems on gas

Thanks Ian.

I've been told this arvo that replacing the inlet duct with the equivalent from an EL is a potential fix as I'm told the EL unit is made from a stronger material.

I just need to know if this is indeed possible without a lot of forcing things to fit.

IAN SCHMIDT

The el can befitted you will have to fit the gas mixer back in the same position but there will be no problem with it

Replace the clips on the airbox with the spring type availiable from ford. It'll save all the plastic if it backfires.

I was amased when I went to my local ford dealer (Courtney & Petterson Heidelberg, and they have a potential solution to this which you should be able to get from any Ford dealer. p/n FO-EETVE 0036 A is a spring clip instead of the conventional clips which hold the two halves of the air cleaner together, idea is, in the event of a backfire, as the gasses expend inside the box, the springs give a little allowing a bit more room and return the lids together afterwards, make sense ? hope that helps,

OK thanks guys.

Anyone have any idea of the part no's for the EL air intake?

What one of my mates did on his taxi was drill a hole in the top of the airbox and then cover it with a piece of rubber that was only screwed in on one side (like a BOV). Those spring clips can also cause headaches. I've had taxi's still explode airboxs with those clips on, take them off all together. The EL elbow is more flexable and therefore can take some movement. The ones in the EF is just hard plastic. They go for about $20 - $50.
