azbret Posted July 21, 2007 Share Posted July 21, 2007 I have read some threads that state you should run larger wires back to the EFI pump. Looking at the wires that are there for my 84 brat they seem to be the same size. is there an amp differance between those pumps or is it just easier to run wires fron the relay instead of tying in the the brats harness???

s'ko Posted July 23, 2007 Share Posted July 23, 2007 not sure of the amp difference. I ran the fuel pump off of the ECU. BW Quote Link to comment Share on other sites More sharing options...
azbret Posted July 23, 2007 Author Share Posted July 23, 2007 did you run seprate wires back to the pump or did you tie into the harness in the car????? THX Bret Quote Link to comment Share on other sites More sharing options...
Psychobaru Posted July 29, 2007 Share Posted July 29, 2007 Are you trying to hook up a EJ22 engine to a EA81 Fuel Pump? If so the EA81 fuel pump will not deliver enough fuel pressure to the engine. Quote Link to comment Share on other sites More sharing options...
azbret Posted July 29, 2007 Author Share Posted July 29, 2007 I'm running the correct type of pump.. just was wondering why people say to run seperate wires back to it instead of using the exsisting wires by just soldering on the new connector for the pump. Then tying into the fuel pump wires in the harness up front at pssenger side door???? Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted July 29, 2007 Share Posted July 29, 2007 Looking at the wires from the ea81t pump and connector, they are definately bigger than n/a ea81 wires. It wouldn't be a bad idea to go ahead and run new. Quote Link to comment Share on other sites More sharing options...
azbret Posted July 29, 2007 Author Share Posted July 29, 2007 What do you think about the ground wire.... tie into the brat harness ground or run seperate, larger ground from engine area???? THX Bret Quote Link to comment Share on other sites More sharing options...
Phizinza Posted July 29, 2007 Share Posted July 29, 2007 I grounded mine to the chassis right by the pump. Quote Link to comment Share on other sites More sharing options...
azbret Posted July 30, 2007 Author Share Posted July 30, 2007 That's what I was thinking of doing. I'll run the same size wire as the one from the relay back to the pump then ground to the chassis. How do I post pictues???? THX Bret Quote Link to comment Share on other sites More sharing options...
