Eric and others, To carry this one step further. We check out the flow rate and the pressure on the fuel distributors for $100.00. If the flow and pressure is not correct, then it has to be opened and rebuilt. Deloreans have to be shimmed from the inside to correct the problems. We can now also replace the SS separator for the chambers with a new one which also doubles as the sealing gasket. John Hervey http://www.specialtauto.com/fuel-dist.shtml
