Hey,

I have a TVS Coyote on 91 oct. 56 lb injectors and BAP. I'm looking to going to e85 soon and want to upgrade the pumps and injectors for it. I was wondering where to buy upgraded fuel pumps. I didn't see them on americanmuscle.com or juggernautpower.com... maybe I'm just not looking well enough. So where do people buy their fuel pumps?

Thanks for the help

Fore, JPC sell systems. If you look up Sai Li on facebook, he also makes systems that are more budget friendly.

Rodeheaver has a new system out that uses twin pump and twin FPDM's for an OE quality installation. It's a 'budget' style kit that is good for 1000RWHP on E85.

Thanks for both of the responses. I will look into all of the suggestions. This is my first time modding a car to this extent. Before, I've just done simple bolt ons. So sorry for my ignorance XD First time even looking at fuel pumps.

Fpdm's on a coyote? Aren't they mechanical returnless?

Yes they are, and the FPDM's cut voltage down in half under normal driving. The pumps only run 100% voltage at WOT. This is why this kit is superior to all others, the pumps don't run 100% voltage all the time so the don't wear out. Large pumps like these will wear out much quicker when run at 100% voltage full time.

This kit also does not use a hobbs switch, so no boost/vacuum leak will cause the 2nd/3rd pump to not turn on which can cause a dangerous lean out at WOT. Both pumps are running 1/2 voltage until WOT where they BOTH are triggered by the Factory ECU to run full voltage. OE trigger, OE pumps, OE quality.

I'm also looking for more information on this kit. Seems to be pretty awesome.
I got on their site, both facebook & webpage but found nothing on the fuel kit.

Info on the fuel system is listed under their online store . My question what is different between the 11-14 fuel systems & the 15 & up? Most fuel systems seem to fit all years.

The 15+ have a larger hat outlet factory stock, the 11-14's do not. You either have to replace the factory plastic line on the 11-14 cars or run an aftermarket fuel line.
The FPDM's are also different.

I'm running Sai Li's kit. No hobbs needed and both pumps do not run all the time. I have the GT500 pumps but I believe the kit he is providing now is with twin GT350 pumps. Haven't had any issues and install was a piece of cake...getting the locking ring off the fuel pump hat was the hardest thing. I would also recommend going with ID1050X injectors. The are E85 friendly and should supply all you need.

This is the kit I plan to run in my ‘18.

I believe Shaun is running this system on his CPR car.
