CJ-Motorsports single 044 setup
 

did any one make how to for the wiring of this pumps... i assume that we will need to use some relays - RP Fuel Pump Relay from rx7.com and 14 gauge wire

i only plan on running single 044 pump in my setup as fitting the twin pumps in the thank with looped 6an lines and level censor is pain :wallbash: :wallbash:

can any one enlighten us...

I used the stock wiring to power a relay and a direct run from the battery to run two pumps. A little splicing is necessary. Not to mention it was a little easier as my battery is in the driver's bin. Is that what you're looking for?

yea if you could give me some info on what relay you used or maybe some pic of wiring that would help

did you maybe use bosch relay

thanks for the diagrams ...

you think this would work

comes with clips and 14ga and 18ga wire 20/30 amps also available in 30/40amps

ebay bosch relay

That is the same relay I used on my car. The harness gives the install a professional look.

did you go with 30/40amp or 20/30 amp

I think I went with the 30/40. I bought mine at car quest.

Relay
 

Thanks for this I been looking for this for a couple days ,
Now I can Probably get 85 RX7 turned on .

Don't run 14 AWG. Run 12 AWG. Technically the 044 will only draw 18 amps but its never a good idea to run so close to the wires maximum recommended ampacity at 60C (20 amps for most consumer grade 14 AWG).

i would say to run a bosch relay, not a bosch "style" relay

It is my understanding that tyco bought bosch relay division and you can not get an actual branded bosch relay anymore.

ive been on the side of the road with a melted cheap relay- thats all im suggesting. They are not created equal go for something "better"

This is what CJM recommends: http://www.summitracing.com/parts/prf-50102

This is actually something that we stock and sell all the time, so we should probably add it to the website as an option when purchasing a twin pump.

At $40, its a pricey option for a relay and wiring, but heres what you would like about it:

It comes with a pre-wired relay receptacle with mounting tab. Just plug the relay in; it will only physically plug in the correct way. Do not concern yourself with terminal/pin numbers, just look at the wires. On each wire it is physically printed in small text every 12" or so where to connect the wire.

Connect the 18 gauge black wire to chassis ground, this is the relay ground.
Connect the 18 gauge yellow wire to switched power (such as stock fuel pump power wire), this is the relay trigger/activation.
Connect the 12 gauge red wire to the battery, this is the battery power for the larger pump
Connect the 12 gauge yellow wire to the fuel pump positive terminal

Included is a circuit breaker you can put inline the red wire. Or you can toss it and put in a standard fuse.

We recommend a separate one of these kits per fuel pump.

Summit sells thos on ebay for bit less

Thos will work just fine 30/40

Either way just make sure you instal them properly

one is summit brand one is painless wiring, but im sure its the same stuff

ok I Will Run 12AWG :nod: I like to listen to advise ,

I bought my relay from Pep Boys it was 10 bucks and My buddy has 2 track rotary cars running this relay and he been happy with them. Well track cars get less use than our daily cars :scratch: so that's the question now

Yea I'm sure we get what we pay for , The RX7 I got had a areomotive a1000 pump and it burned out cuz no relay so Im taking the extra step in doing it right , Maybe later on I will get a better relay . Ill keep and eye on it.,
O I did double check or should I say triipleeeeee check lol . I'm buying toggle switch , Fuse for it , and a Indicator light.
