FMU install help

[Perkul8r]

Ok, so i am adding a turbo setup to my 1998 Leggy L. I got a FMU from my buddy for free. But its a cheap Ebay one and isn't labeled with in and out for the fuel line. I have been searching the net for an install diagram of some sort, but haven't found much. The problem i am having, is the fittings look weird compared to other FMU's.

The fitting on the very top is a bigger one, Looks pretty big to be a vacuum fitting.

The two fittings on the bottom are different too. The one in the middle is smaller, looks more like a vacuum fitting, and the one on the side is bigger like the one on top.

Is is possible that the fittings on top and middle got messed up? and also, which way do i install this. I was also wondering if anyone knew for sure which fuel line was the return line at the manifold.
Thanks for any info.

In all seriousness.
i would not trust a "cheap e-bay" FPR as far as i could throw it (probably a good option actually)

grab a good quality Sard or Turbosmart and a liquid/ oil filled gauge.

adequate and consitsent fuel pressure is very important in any boosted car. otherwise you're going to have a re-build on your hands very quickly

Well, i was just looking at prices for those, the turbosmart FPR 800, and i would love to get one, and probably will sometime, but i really dont have that kind of money right yet, and i am just trying to get the car going. My family is down to 1 car and with they wife gettin a new job, i really need to get it running again. Is there something else besides that FMU that would work good that i could possibly get? i am pretty good with all the mechanical on adding a turbo to a na motor, but EM is where i am lost.
