You want to use the hose that comes outta the rail in a barb ( upper, in your pic ) to connect to the FMU. The Fuel inlet ( lower, in your pic ) is the High Pressure Feed line.

Good Luck

Can I install the fmu inside the engine bay. I can place it on the firewall. anyone done this?

Go for it, connect four! yeah buddy, us 95's are able to mount our FMU's in the engine bay. Mine is on the passenger side of firewall where black cruise control box would be if I had it. That makes it easy to run a little vac line to the stock fpr right in front of it. Then run your return line from rail to fmu in, and fmu out back to the hard line on the firewall. I had 1/4" fuel line, and it works great, just make sure you use those stock clamps still, or you might have fuel spewing out when u start the car hehe (not speaking from experience )

Good luck, and let us know how it works out

what the fu##?????? looks like someone tried to make a fmu into a sfmu of something. never seen that before.

 

[black4banger]

Yeah exactly my reaction. When i turn it a metal valve*like..thing goes up like if its to let some fuel out from there.

Did you buy it from a private seller on ebay or was it one of those companies that sells on their?

 

[black4banger]

Bought it off a regular ebayer. No company. http://cgi.ebay.com/ebaymotors/ws/e...d=1,1&item=7977903478&sspagename=STRK:MEWN:IT

Looks like somone tried to make a Bleed Valve like the SFMU uses.

 

[black4banger]

i emailed the buyer to see what that valve is for. here is his response........


When I originally ordered the FMU from Vortech, I had the same question
regarding the valve. From what they told me and the gentleman that
tuned my
car on the dyno in Scarborough, Canada...it does not get a "hose"
connection
to it, however you use to bleed on and off pressure to help reach your
12:1
ratio.

Hope this bit of info helps.

 

[black4banger]

Anyone got a idea how im going to get it to 12:1 ratio????????

 

[black4banger]

Vortech info:
This valve has been modified to accept some sort of bleed assembly. The idea is to use the valve to control the amount of pressure that the upper chamber is seeing. It is in essence, a controlled vacuum leak. I would begin to tune the vehicle with the valve fully closed, then open the valve if the fuel pressure is too high. Continue to gradually open the valve until desired fuel pressure is obtained while under boost.

Turbo guys ........what fuel psi do you see at 5-6 psi of boost?

I have a Warblo 255, 12:1 FMU, stock injectors. I see a constant 76-79 psi. I don't know what its really supposed to be at with the FMU... I don't really like it being so high... I need a new fuel system. Also, what are all you other Star Stage 2 guys running for Vac at idle?
