Hi guys, im having problems with injection system, in 1800 to 2300 RPM seems like fuel ratio is lean and truck starts to going up and down... pump pressure is good 40psi, injectors are new, the only thing i never check was FUEL RAILS , and today i saw some leaking on both sides of each rail, what rails do you recommend to buy? i find a couple any opinion?

If that's an LS based system, the fuel psi should be 58, not 40...
Leaks:
Wrong o'rings on the injs.
Injs are too long/short to fit the rail mount dimension.
Rails are not being held in place by the mounts.
