On the vortech fuel rail driver side, it has two thread holes. one on the end which gets block and one in the middle of the rail for fuel pressure guage or fmy conection.. here is link for visual
http://www.vortechsuperchargers.com/pdf/manuals/50fuelrailim.pdf
Can i block the middle thread opening and run the other opening at the end of the fuel rail for the regulator or fmu.
hope i make sense here. ![[patriot]](graemlins/patriot.gif)

yes u can, but there is a reason it has the middle outlet, when u have a fitting where the plug goes in those directions it usually hits the distributor, so either keep the middle outlet or do a small cap conversion, either will work
can i ask why u dont want to use the middle port ![[Confused]](confused.gif)

and if running that big of a fuel rail, and an aftermarket regualtor, why in the hell are u going to be running an FMU, those are bandaids, just use the right size injector and proper tune

I got 42# injectors with the Rails in.. what im getting stuck on is the section with the FMU and the main fuel line... the stock Rails split into two. one rail went to the FMU and the other is the main fuel line.. Two questions... if im not running the FMU so that line is gone.. I still have the main line connection, what are thoes stock fuel connection fittings.. they are round with the circle spring inside??? how do get thoes apart? here is pic of where im at. im going to run a 90 degree fitting off the middle driver side rail to a regulator  . no room at the end of rail like you said.

red x on the photo
on the connections, one is the supply line and one is the return, if thats not what ur looking for then i didnt understand the question
and u need special little clips that push into the connections to remove them, they are fuel line/AC line disonnect tools, u can get them at any auto parts store

yeah, about the two lines. after the fmu is gone there is only one fuel line to the fuel rails. Is that right.

You need one line in (supply), one line out (return). Whatever your FMU was linked to, hook that back up, minus the FMU.

Ok, i figured it out.. the return line was going into the FMU. i unplugged that and ditched the FMU.... now the return line will go to regulator into driveside fitting. the main line gets dumped into passenger side feed.
Do you know where to get random fuel fittins and hose? not something Kragen would sell..
