After extensive testing I'm proud to announce the very first completely Plug & Play Fuel Pump Hardwire Kit for the GTR.

This PNP Kit bypasses the factory voltage limitations on stock wiring by direct wiring fuel pumps to battery. It'll increase power output from 12V to battery voltage (14V+). With direct battery voltage your are now able to maximize the pumps flow, allowing for more head room on cars with injectors that are maxing out.

A not so well known issue with hard wiring upgraded fuel pumps is it can overrun your fuel pressure regulator at idle, causing your fuel pressure slowly to rise when it shouldn't. This kit solves that problem because it still allows the fuel pump controller to switch the primary pump from low, medium and high speed.

The kit comes in a carefully prepared two piece wiring harness. Relays and fuses are placed at the beginning of the harness so they can be close to the battery.

You literally connect the one end of the harness to the battery and the other connects to the fuel pump basket and factory engine harness.

Everything is plug and play so the kit can easily be uninstalled at any time - No more cutting the factory wiring harness!!



The kit can be purchased directly off my website - Here

For those interested I'll post up more pictures soon!

I haven't seen the AMS kit before but and seen people post about it. From what I read it's not a plug and play kit .. You need to cut wires and anything with a hobb switch removes the ecu from controlling the secondary fuel pump.

So the main difference - my kit is 100% complete and plug & play. You don't have to cut any wires.. No one likes cutting wires.

It's hard to comment on another kit that I've never seen before and that doesn't appear to be for sale anywhere on the internet.

But when you compare a non plug and play kit with a plug and play kit you can pretty much guarantee a price difference.

The hardest part about installing this kit is running the wire in the car - and that's pretty easy.

Shops normally charge at least 2 hours of labor plus parts to hardwire the fuel pumps and what they're doing can't be undone like a plug and play harness..Then you have to hope they found the right GTR Fourm thread that explains how to wire the pumps... I'm not joking.

Over the course of building this kit I spoke to several people about how they wire the pumps, and I found not everyone does it the same. I can't even begin to tell you how many cars I've been in that the pumps run the moment the key is turned on... it pisses me off.. your working on a 100k car and can't even take a moment to wire up the pumps "correctly" - yeah it works but it's not "right". I looked at all the popular online threads and quickly realized why some people were having problems so decided to stop looking at what people have done and start fresh.

This kit is a quick and easy solution for a lot of people, already have a few shops begging me for the kit

This takes a kit that most would probably pay labor to have installed....and makes it something you can do in your home garage with an hour of free time.

I think for not having to cut your factory harness, its WELL worth any additional expense.

This can be easily removed if you sold the car, with zero trace of it ever being there. (Allowing you to re-sell, something you can't do once you've hard wired your factory harness.)

$400 is a very fair deal and I wish you much success with this product. I'll be dialing your digits for many I feel confident, as there are LOTS of customers who have been asking if this sort of product exists.

How does this work with an aftermarket basket like Fore? I assume it shouldn't make a difference and work as expected, but I figure I ask for those of us that don't have OEM baskets anymore.

Nice work John. This is an absolutely necessary mod for all model years.

The rear ground was designed to go on the seat belt bolt but has enough length to be put somewhere else in that area.

Your fuel pumps is going to flow more at battery voltage (14v) than at 12 volts, so it should drop your injector duty as long as you dont have major fuel filter issue

Hope that helps

Let me know if you have anymore questions

Pretty much everyone is going to want the kit without the hobb switch.

Hobb switch kit is good if your having a problem triggering the second pump using the factory ecu or have some personal preference - but you end up with the same result in both kits.

For you, hobb-less kit

I would be more than glad to take this to PM but please don't make this out to seem like something it's not.

I have plenty of hard wire kits in stock, and plenty of fuel pressure kits.

Since you are over seas I told Chris @ SBD I would include a fuel fitting you would need to run the Fuel Pressure Sensor - something that is not included in anyone's kit.

This was to make it easier on you, I can get a purple version of the part but it looks very ugly so I ordered more black fittings..i was promised I'd have the part on Friday so I could have your shipment in the mail that same day.

When it didn't arrive I was promised Monday.

I wasn't given a tracking number but I'm still waiting for the fedex guy to arrive to office

I'd be more than glad to send you everything minus the extra fitting I was supplying to make your life easier

Please let me know!

Taking your fuel system to the next level and still want plug and play wiring?..

You asked and now you shall receive!

Here is our new plug and play fore innovation harness for dual pump systems.

This harness connects the fore innovation system to our existing non-hobb hardwire kit.



Several of you have also requested a harness for triple pump setups.. I'll have those available very soon!

If you have any requests just shoot me a PM, would be glad to help

Yes and No.

You can hardwire the fuel pump controller, then run new wires from the controller to the fuel pumps but the fuel pump controller hardware wont be able to handle it - this is why we need to bypass it - which causes the fuel pump error codes.

If your looking for the best performance for your fuel pumps you wont want to be messing with that controller.
