I'm stripping down my new JN (89 Fox) block, and I have noticed that the fuel distributer is a 80mm thin lipped one, but it is CIS-E (has a DPR). What happens to the fuel pressure in a CIS-E system when the DPR is completely unplugged, does is default to some middle value so that I can use in my CIS-Basic (no lambda) Scirocco? Wondering....
