Very confused on how to wire up the 2 pumps i have. Some people are telling me i have to run a small amp?!?!?!

Looked for threads but cant find anything. Can anyone help me out here.

Please and thank you!

 

no amp. you need to run a relay

power wire directly from your battery. ground it nearby. and use the stock fuel pump wires as a signal to unlatch the relays ( make it work)

 

we run the + wires to a snow plowing solenoid up front then get power to the solenoid from the alternator and take the main relay fuel pump signal wire to the solenoid and that would activate the pumps when the ignition kicks in

 

If i wire them both directly to the power o the battery. Wont the pumps be on all the time???

 

What the hell is a snow plowing solenoid?!?!?!

 

the relay needs a switched input to send power.

There are 4poles onn your relay,
Ground to chassis
Power in from battery
Power out to pump
Switched power stock fuel pump positive wire

 

Do any of you guys know what color the wire are that send the fuel pump signal.

 

do you have a hayne's manual for the car? or anytype of manual? I would definitly suggest buying one.

I have a civic but I do not konw if there the same color wires!

Some guys use snow plow solenoids. Alot of nitous guys use starter solenoids for the nitrous and fuel solenoids. Very effective and durable. The little relays dont hold enough amps.

 

What guage wire do you guys reccomend i use???

 

relay would go something like this:
87 12 Volt battery
86 ground
85 from the factory fuel pump wire
30 to the new fuel pumps

 

What do those numbers stand for.?? Excuse my ignorance.

Wiring is my flaw.

 

They are terminal numbers for the relay.

 

BOSCH RELAYS HOLD plenty of amperage.

 

X2. They're rated for 30A. I always order them from Parts Express, with the sockets. Relays are $2.89, sockets are $1.75.

 

i run one relay for each pump
and one circuit breaker for each pump

 

run two relays one for each pump.

 

Bosch relays would be the ones to buy!

 

he said 2 pumps up top but is he talking about in his intake one also or two separate bosch. I just thought he was running side by side pumps. but idk lol just trying to help.

 

if you look at his build I dont think he needs 2 bosch fuel pumps, its still a street car.

 

Main reason im running the 2 pumps is get the pressure need to run the new saturated bosch injectors to flow properly and meet my WHP goal.

 

Thank you guys for the input. Now how does this sound. Run each pump with its on realy, like this:

87 12 Volt battery
86 ground
85 Ignition
30 to the new fuel pumps


What do you guys think??

 

Hook them up according to the chart above, dont make more out of it than necessary. I have my Inline 255hp and my Intank 255hp hooked up exactly like that chart with 2 Bosch Relays wired with fuses right off the battery, or you could use the alternator output w/e is easier for you.

 

Will do. What guage wire do you guys reccomend??
