mldc Posted November 23, 2016 Report Share Posted November 23, 2016 (edited) Hi guys,So we manage to get 8 new injectors for the engine ( Siemens Deka 630cc ) and now we want to add second fuel pump for better flow.Here's the wiring diagram I've made, is this right or i've made a mistake? Pumps will run sequentially at the same time. Also, what current relays and fuses should I use?Thanks for support guys,Dual pump.bmp Edited November 23, 2016 by mldc Quote Link to comment Share on other sites More sharing options...
Scott Posted November 24, 2016 Report Share Posted November 24, 2016 Your wiring diagram looks correct. I think this is the datasheet for your fuel pumps:http://www.bosch-motorsport.com/media/catalog_resources/Fuel_Pump_FP_200_Datasheet_51_en_2776426379pdf.pdfAccording to this the pumps will draw about 15 amps each. I would recommend a 30 amps relay and 20 or 25 amp fuse per pump.Scott Quote Link to comment Share on other sites More sharing options...
