The factory fuel pump wiring, 1.5mm in diameter (slightler larger than 16 ga) is sized for the less than 10 amps the factory fuel pump draws. Most aftermarket pumps require more than 10 amps of current - and when using the small factory fuel pump wiring, the aftermarket fuel pump can flow much less than expected, and may cause a safety issue.

ScienceofSpeed has designed a fuel pump wiring harness that replaces the factory wiring to supply 20 amps of current to either a single in-tank pump or 60 amps of current to two or three pumps (when a surge tank is used).

Especially important is the factory terminals that ScienceofSpeed has sourced from Japan to use with the factory electrical terminals. This allows 12 ga wiring to be ran in to the factory fuel pump carrier connectors all the way to the pump!

Two kits are offered:

• single-in-tank fuel pump wiring kit: feeds one pump in the factory fuel tank
• multi-fuel pump wiring kit: feeds power to the pump in the factory fuel tank, and one or two additional pumps in the ScienceofSpeed Surge Fuel Tank. Wiring kit allows staging third pump only when needed (when required by power demand).

Nice! Will u have instructions or create a DIY?

 

Thorough instructions with photos and diagrams are included.

 

Looks good guys

 

I'm about to install a single Walbro e85 400 pump. Will this wiring kit work for me?

 

I think i got this with my order already.

 

I would love to see a picture of everything that is included with the single fuel pump wiring kit.

 

Yes, the single pump kit is exactly what you need. There are so many components, that a photo showing the kit would be difficult - however, there is a wiring diagram and a description of what is included on the website. Everything that you need for installation is included - we've left nothing out down to every terminal, wire, etc

 

Does this kit replace the male "spade" terminals in the holder assembly? Or does it need to be replaced?



They can be barely seen in the pic.

 

The molded in terminals to the carrier are preserved. The connector that attaches to them is also preserved using the larger gauge terminals that we supply imported from Honda's OEM in Japan.
