I need some help guys. I am unsure of how I should tap into my fuel. I have a t fitting but would rather go to the fuel rail. I can't find the fitting for it though. I have a radix on the lq9 in my 03 Silverado SS. Would the fitting for the rail be different than stock if anyone can help me find it. I have only been able to find the one for ford and a dry tube for gm.

Pics would really help to if there is a better way. I am trying to go for show too.

TIA,
Justin

 

there should be a port on the driver side rail to get fuel from 1/8npt maybe? That would be the ideal spot. If it is a 1/8 go with a adapter fitting from 1/8npt to -4 for you fuel noid.

 

I installed a NX kit on the Wood Haulers truck. On his, which is an 02 4.8l, on the passenger side rail, on the front end, I unscrewed the cap and removed the schrader valve core and his line supplied screwed on to the end of the fuel rail and went to the solenoid. Hopefully this helps!

 

do like he said. looks just like a valve stem take that out and your fuel line will screw right on there that goes to your solenoid. pretty easy install

 

I can't get it off now to even look how I might get it hooked up. I used a hex key with a breaker bar and couldn't get it to budge. I bench 225 and it wouldn't go. WTF? These are the fuel rails that came with the radix btw.

 

umm. ill go take a picture of what you need to take off.

 

arent the fuel rails different on a radix??? maybe this will help. looks as though the allen head screw should or can be removed. pm blownchevy.

 

I think BlownChevy SS is wanting to tap into the fuel at the end of the fuel rails. You can see the 2 hex plugs in the picture. His question was if anybody knew what fittings would fit them. They appear to be a bit odd sized. I'm with him. When I installed my fuel pressure sender I wanted to tap into the fuel in the end of the rails. I couldn't find the fittings to fit and wound up going into the schrader valve and it looks like *** on mine.

 

Digging up an old post for some help. I am getting a LS1 wet kit. To hook the fuel line up I am supposed to unscrew the schrader valve and install the pressure safety switch and fuel line into the fuel rail whre the schrader was. Problem... I already have tapped into the old shcrader valve location with my fuel pressure gauge sending unit. SO...does anyone know where I can get a "T" fitting that wil accept the sending unit (1/8") and the NO2 line (1/8" I think) and screw into the schrader valve location. Geez, what a long question....

 

NOS 16103 is the pn for the fuel rail t to allow you to have a fuel pressure sending unit plugged in and tap into the fuel rail for the fuel line for the nitrous.
