I've gone through a Walbro and now a DW200 and still the same problems. THE DIFINITIVE FIX FOR FUEL CUT ON HIGH G LEFTS AND ANY RANDOM LOSS OF FUEL PRESSURE IN A LOWER END HP BOOSTED, STREET, LIGHT TRACK DUTY CAR IS TO ONLY USE A BRAND NEW SLIGHTLY MODDED TO FIT SERIES 2 FUEL PUMP ASSEMBLY. DO NOT PUT HIGH FLOW PUMPS IN A SERIES 1 ASSEMBLY IT DOES NOT WORK. I HAVE DONE IT TWICE NOW AND IT STILL DOESN'T WORK! SERIES 2 OEM Fuel Pump Assembly part no. N3R1-13-35Z Some Modifications to fit in a Series 1 fuel tank is required.
