haiku88 Posted March 30, 2008 Share Posted March 30, 2008 edit: Got a reply from Dunnell, the correct fuel pressure is 275 kPa or about 40psi. I had a lower ball joint fail in the meantime so I have not checked it yet. Also, Pete Challinor very generously offered to help me out via telephone.... Bill :7frog: am troubleshooting and modifying my Dunnell FI system and am hoping someone here could help with some specs, tried emailing Dunnell but no reply so far, and a Google search did not help either. Need the flow rate on the 175 hp injectors and also need the spec on fuel pressure. Slomove already made a good estimate on the injectors (300 cc/min) but maybe someone has Dunnells numbers...and am curious on the pressure spec as my car has a pressure regulator with a disconnected vacuum fitting, am fairly sure this is the cause of rich running and poor mileage but a FP specification would help to confirm and correct this....
