[QUOTE="Tazza, post: 18495, member: 82"] Pressure to the pump should only be a few PSI Pressure at the delivery nozzles is 2-3,000 PSI, there only looks like a water droplet every time you get an injection cycle. It doesn't take much fuel when its in a fine mist to do the job. I'm still thinking you may have sticky injectors, these can cause the fuel to just drip into the cylinder and cause black smoke and destroy the piston over time. Or it can have an odd spray pattern that will cause black smoke and hard running. See if you can check the compression, its the best place to start. No point changing injectors if your compression is way down. The 453 i have uses an electric solenoids and not a pull cable. [/QUOTE]
