Default Flex Fuel Kits

Finally getting my Z back in the shop, and shopping around for a few upgraded parts that are fuel related.

Main question, who is producing a flex fuel kit I can purchase that folks have used & liked? Will be switching to ECUtek, have the GTM Stage 1.5 upgrade kit going in from my Stage 1 so hoping to do some nice fuel upgrades while this is going on, plus see how far we can go with the SC kit.

My current thoughts on upgrades:
Injectors - ID 1000
Fuel Pump - Aeromotive 340
Spark Plugs - HKS (Need to look up part #)
Flex Fuel kit - Open to suggestions on what others have used.
Return Fuel System - Open to suggestions on what others have used.

I would go higher on the pump if you plan on making more than 525whp on E85.

Cant go wrong with CJM's return kits. His customer service is amazing and he sells a high majority of kits to the Z platforms.

That would do it. I was having mad pressure drop with the stealth past 6500K at 525whp on E. The stealth does run quieter and wont heat your fuel up as much so if you dont plan on anything past 515 or so I would leave it.

Not 100% sure how far we will get with the GTM kit, I know one member has gone E with the 1.5 kit but he only had the 88mm pulley. I have one of the rare 84mm which I want to see how far we can go.

Good to know, I will make a note of that and compare them.

Walbro 485 and ID1300s are a good combo.



Do not run the 450, or the ID1000s with ethanol as they will get destroyed. The 450 will fall apart from the inside out, and the ID1000s will corrode and clog. E85 is a very corrosive fuel and needs the components designed to withstand it.


The 1300s and 1700s where designed specifically to work with Ethanol fuels and not fail.




CJM Return kit is also a great option for your needs.

I too was having the exact same issues with the stealth one, switched over to a walbro 450 and made a huge difference, everything nice and Rich up top now!

I had the Zeitronix Flex Fuel Kit installed along with a content analyzer.

Im sure they do work for you, but they are not ideal. The 1300 and 1700 where from my understanding designed with stainless components to prevent the "rust" found on other units.

The all new ID1050x will replace the 1000 and all lower units and be designed around the 1300 and 1700 from what I gather. There has to be a reason for that, ID is to smart to just make random changes.

If I am wrong and Paul says I am a moron, I will accept that.

AAM has a flex fuel kit for 699. It includes innovative gauge, sensor, fuel connections, wiring for ecutek. I didn't have to buy anything extra with that kit.

Bigger lines
Fuel pressure regulator

I'm doing the Walbro 485/CJM combo

Can't speak to the injectors, I'd have went with ID1000's for flex too
