Just wondering what is the best brand / type of LGP equipment to install on an AU3?

for both vapor and direct injection?

There is no 'best'.

It really depends on what your installer normally uses and is comfortable with.
Just stay the hell away from cheap s**t.

We are currently trying to help some people who went the cheap vapor injection option.
The original installer has closed up and can't be contacted. The Polish manufacturer is playing games with them and currently has been given the money for the replacement parts but is refusing to send them.


We are seriously considering removing the system and fitting Sprintgas vapor injection.
