Message	Going with a Walbro 450 pump and would like to keep the stock wiring and control. I test the pump for current draw at different voltages but only under free flowing conditions in a bucket of water. I tried blocking the output with my thumb to check current at a higher load but the test was nowhere near what you might expect in a true closed system under greater pressure. Otherwise the amp draw looked acceptable. Guess ill have to fab something up with a pressure gauge to find true current levels. www.mytwinturbo.com Nissan Data Voice - The first Nissan diagnostic software with a voice! src="http://www.nissandatavoice.com/images/nissandatavoiceqrcodes mall.jpg"> Nissan Data Voice on YouTube href="http://www.mytwinturbo.com/software/Nissan300ZXVINModelL ookupV2.3.zip">Download my Nissan 300ZX Vin/Model Lookup.
