Demon/Redeye Fuel Pump into Hellcat

I have been searching and reviving some threads over the past couple of days, but no one has addressed my specific question.

I have a 2015 Hellcat and need more fueling. I prefer a stock fuel basket because it keeps the fuel on the pump, and it also cools the pump. Pumps just last much longer in this scenario. I know the Demon/Redyeye comes with two pumps in a stock basket with two fuel controllers. Tapped Performance has developed a dual pump kit with a Fore hat for hellcat and a Y splitter with a second fuel controller found here: 2015+ Stage 1 Hellcat Fuel System

This just uses fuel socks with no basket. I am considering this while adding two Holley Hyrdamats found here: Hydramat Fuel Filter Sock by Holley

I wonder if the stock Demon/Redeye pumps could be used with the Y splitter tech developed by Tapped.

Another option is to use a boost-a-pump and retain the stock fuel pump and basket. I would prefer not to use a hobbs/boost switch (Kenne Bell) or the throttle pedal kit from JMS so that the car sees a big change in pressure. I would think you could run the BAP all the time and just scale the fueling in the tune.

Thanks for reading. Advice is welcome.

That's the issue with the demon/redeye pumps is it requires the second FMU . If you can find a way to make this work please let us know . It would be a pretty good system for most people .

I spoke to Rick at Tapped Performance this morning. He is pretty sharp. It is doable, but you need the jet pump from the passenger side in the Redeye as well. You could use his system with the extra fuel controller, and with a little wiring, you would be in business. He said a few people have asked the same thing, but it is expensive compared to BAPs or a drop in dual pump setup. I am mulling over my options and might try it. I would still love to here from anyone that has done it.

I just installed the TAPPED dual pump system using their wiring harnesses, top notch stuff but also had this same wonder, why can’t the Redeye dual pump setup be used. I saw once but don’t remember the dealer a dodge dealership developed their own dual pump system that uses a basket. I’ll see see if I can find it.

So just wondering why you can’t use the redeye system in the regular hellcat the plugs are the same as the regular hellcat and the fuel exit the same. If you have the tune and injectors like I did. I already had the fore dual pump but I’m upgrading to the redeye system with the dual driver and what looks to be a pump or something on the passenger side also. Like I said even the plugs are the same the absolute worst it could be is the second fuel pump module and I already have it from dual pumps and if it is a fuel module in the passenger side which it’s not as there is only 2 wires coming from it and that’s the fuel level sensor. Same as the old style passenger but idk I’m tryin to buy one now

Which has the same plugs same everything other than whatever that is on the side of it I had thought it was a pump but no wiring to power it I’m not sure unless it piggyback off the little going to level sensor prolly a Venturi or jet pump like others idk. I know the older ones like I have stock have 2 springs that get worn out pretty quick if hot. I’m asking really because I was gonna purchase the redeye set any info would be appreciated. Thanks in advance also im fairly positive it will work it’s more less same thing just with the factory dual instead of single
