Hey guys, I changed the fuel feed line and thought I would snap off a few pictures. Seems like when you make over 450 rwhp then spray it it taxes the test port too hard when the solenoids first open up. Fuel pressure doesn't drop over the run but momentary spikes (or drops) when the nitrous first hits. What I did was tap into the fuel system at the tank. This keeps the 8 foot of 3/8's line from spiking when the solenoid first opens. Its almost like having a fuel accumulator up front.

I used a High flow Y, two GM female 3/8 fuel line fittings, a female union and about 8 feet of -6 AN Teflon lined hose. You can use rubber stainless hose here but the Teflon does a much better job for fuel in my opinion. Regular stainless hose will sweat fuel smells.

Sure I can get them in all DIY form. The only thing I didn't like is it was super hard to push the female GM quick disconnect over the factory plastic male coming out over the tank. I measured it and it was a couple thousands off.. I don't know if I just got a wierd one or the plastic made it hard to push it on. If your interested I can put together a parts list for you to make it yourself. It totally solves the little lean spike and low fuel pressure when grabbing fuel off the rail for a wet shot.

You guys want me to put a little DIY kit together? Some un cut line, the fittings, and a simple diagram. I can make it an option when buying the nitrous bracket from us.

It's a good idea for the guys over spraying past 550 at the wheels. :cheers1:

I'd love to see a diy kit from u. It would make me feel much more comfortable going up to a 150 shot
