Looks good, but why cant you just drill the hole instead of cutting the side out of the rocker box? Could you use another fuel rail grommet at the new port, or is the custom line dif size than the factory rail inlet?

Grommets come in all sizes. I have some concerns about this.

its something new to the market of course people are gonna have to find something to complain about

It's a good deal for someone needing dual pumps, I think it's too bad that part couldn't have been a little better executed. I personally don't like the idea of cutting up my rocker box and sealing it with RTV, but that's just me.

It'll most likely be executed more efficiently down the road. Ill let Josh know everyone has this big issue with it..

There's trucks out there with large fuel with these, no problem, remember, a cp3 can be maxxed to much higher capacity than a k16 with less durability issues.

Reliability, we tested this set up for 18 months before it went live, and Matt from Spartan has had his kit a while now as well, maybe he will chime in..

I am not complaining about it at all it looks good, was just asking if a grommet could be used is all. Its kinda hard to tell if there is room to install one in the pic. Its not a big deal to me either way.

so the pump only feeds one rail?

Yes but that really doesnt matter since they are both common rails the pressure equalizes in both rails, in an ideal world you would want one pump feeding each rail with a crossover tube or something to equalize pressure in both rails, in conjunction with a rail pressure sensor in both rails to make sure they are both equal, but for the most part feeding one rail isnt a big deal




As far as bitching about the rocker box mod, i just think that most people dont feel comfortable with that much silicon near the engine, as well as dealing with possible leaks with the valve cover and the rail. I do agree however that only having one line is much simpler than adding 4-5 lines like other kits, basically a trade-off on what each person feels is the best way to do it.


Craig has your truck been running yet since the pump swap?

If you look at the 4th picture it goes from the pump, through the rocker box, then into the passenger rail. So it feeds one rail, but pressure should equal.
