Need help please...I've got a TOMEI fuel pressure regulator I want to install but not sure what type of adapter to use on the end of the fuel rail when the original fpr is removed. There are loads on ebay for Mitsubishi's but I'm not sure which one I need for a 6G74. Does anyone have info that would help?

How about this one?

You have the measurements right there. You can pop off one end on the fuel rail and measure it all out and check it to those listed on that ebay listing.

Thanks mate. Was just seeing if anyone had the info to hand so I could avoid removing the part.
