Leaky injector cm2350

[Starlight]

Fuel return flow tests need to be run on the injectors and fuel pump head if you replaced the regulator and it didnt fix the problem. Any part on the 2350 fuel system is expensive and you dont want to replace anything without finding and narrowing down the problem. By far the most common thing is a leaking injector. To find which one is a process. It could also be a fuel tube connector not at the proper torque. Have found that also to be a problem and after having all the connectors properly torqued it fixed a leak that put fuel pressure from 8 -9k to 150 in 30 seconds to a system that held 7k pressure overnight.
