well time has come to wire in my inline fuel pump.
i have a Bosch 044 inline and also a walboro intake 255.
i honestly have no clue on how to wire it in. ive looked online for something. only found stuff thats close but still confusing for me.
see if i can explain this.
pump has two wires.
1. ground (this ones obv)
2. power. the power goes to a relay.

the power wire goes in and 3 wires come out of the relay.
now one of the wires should be the power but where do the other 2 go?

this was installed in another civic 2 years ago. and i didnt take it out so idk how it was setup.
one the the wires off the relay look to be a ground since its short and the end on it to be bolted to the frame or whatever bolt it close.

all in all im lost. someone help me please haha

Use a multimeter for 30 seconds and figure out which is 12v and ground. Use this to trigger a relay that gets it's power right from battery.
where does the 3rd wire go?
and il take it to work use a multimeter on there. thanks for that advice i feel like a tard for not thinking that myself

On the relay, one should go to the pump, one to ground, one has power coming into the relay from the batt, and one a switched 12 volt to activate (close the eloctro-magnetic switch in the relay) the relay. I dont remeber which goes where on the relay, but it should have a diagram on the side. Gl

I had an inline installed once...
ground, 12+ power, and ran the 3rd wire to the wire on the replay that turned on when the intank fuel pump kicked on.
done a google search a while back to figure out which one it was.. been about 2-3 years ago.. was a light brown wire I believe...

red wire= 12 volts from battery

white wire=ground

yellow wire=to pump

black wire=trigger source (maybe 12 volt switch source)

id suggest ditching that relay and getting a good, high amperage relay. preferably not made in china...
could you give me a suggestion on which relay? idk where or what kind of relays i would need to get

You should have it setup not to run all the time only when you say get above 10psi and a hobb switch or thru the ecu can be set as tps % or rpm so the fuel is not heated up or drawing extra power and it can last longer.

if he is running a walbro in tank and a bosch inline i hope its a "race" car. otherwise the walbro would likely be plenty.
yes it will be a track car. running e85 for fuel. with 1600cc injectors.
maybe a little overkill. but for the power im wanting i doubt a intank 255 would do it.
