O.K., I replaced the secondary and return line fuel filters last night, I pre filled the secondary (spin on) filter with Biobor, lit it off and revved the engine a bit to clear out any air bubbles, the car now idles pretty smoothly and runs like a scalded cat as it used to years ago .I got 415 miles before the low fuel lamp went on and filled up at 440 miles, adding more Biobor to the tank as aprophylactic measure .
To - day's question is ? with way to turn the ALDA adjusting screw to lean it out a little bit ? .
The fuel economy remains low @ 23.1 MPG's, this injection pump came off a very clean wrecked 1985 300SD and the ALDA has clearly been touched before ~ maybe someone richened it up to make that big heavy car faster .
I remember some here fiddled with this a while back and said a 1/16th turn of the adjuster screw made a big difference ~ I'm pleased with how well the car runs now (80MPH @ 1/4 throttle) but it's still smkin more than I want along with low fuel economy .
Thoughts ? .
TIA,
-Nate
