Dunnell EFI Zetec 175 hp questions...

[haiku88]

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....

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....
