I have a 1987 E-150 with the 4.9l staight six that has a CNG dual fuel system istalled in it. However, it hasn't worked since i got it, previous owner seemed to remove the tank and cut the power somewhere.

I've been wanting to get it running, but can't find anyone that knows anything about it. I don't know if it is a factory setup, my VIN num says it's not at least to my van, but never know about a swap...

All the CNG components are from a company called Landi Renzo, but their website is all in Italian, and they wont reply to my e-mails.

Anyone able to help me out at all?
