I started a previous discussion about trouble I was having with hot starts. I got good advice and have had less trouble recently.
In that thread it was suggested that using the high boost pump to fill the fuel lines will not flood the engine because the fuel is recirculated back to the fuel tank...but that's not how my set-up works. Here's what I'm seeing:
With the fuel lines empty (hot start conditions) and at idle-cutoff, it takes about 15 seconds to fill the lines with high boost
After 15 seconds of high boost and still at idle-cutoff, fuel begins to run out the drain lines (its a healthy stream)
Adjusting the idle-cutoff in by about 1/4 to 1/2" does not stop the fuel from running out the drain
My engine is the MB version. The fuel pump has been rebuilt twice under my ownership (17 years)
So what's going on here? I'm trying to understand how the system is working so I don't start messing up the hot-starts.
Thanks
