Coyote Fuel Setup

[richtersand]

Hi all, wanted to get feedback on my fuel setup for the Coyote. Diagram is below, and here are links to the hardware. Thanks in advance for any thoughts/suggestions!

Deluxe LS fuel regulator with 6AN built in

that regulator/filter will work with the Gen1/Gen2 Coyote engines at 55-58PSI
Gen3 needs 65PSI due to direct injection - my setup has the Aeromotive Stealth 340lph #11542 (https://amzn.to/3psLAsX), Aeromotive 12347 Filter (https://amzn.to/3otqn0k), and Aeromotive 13136 Regulator (https://amzn.to/3oziMha) but I also have a Boyd's Tank which is different from the regular Mustang tank

I’m assuming the quick connects from fuel hangar to GM regulator/filter? Mine is pretty much the exact setup. I was concerned about the amount of connections but works great. I was happier with running a rigid nicop line down the frame rail in place of the plastic line that Forte provides. I think the suggestion is running that down the tunnel which didn’t fly with me.

Looks good!

Thanks guys. Toadster, I did some searching around and it looks like you are right on the 58 PSI GM/LS regulator vs. 65 PSI needed for Gen 3 Coyote. So it looks like I have to go to an aeromotive regulator + filter setup. Can others confirm that the GM/LS regulator won't work for the gen 3?

Its correct the Gen3 needs a higher pressure so I would assume it will not work.

I ran SS line the whole way. Didn't have good luck with making the right bends with nicop (where I was happy with how it looked). Plus the flex of the non-hard line gives you a little bit of safety if you hit something its more likely to bend then break. I also ran my lines direct to the rail then regulated after.

Michael, I agree with using flex line for the entire distance. But I'm scratching my head about your comment "regulated after". Could you explain, please? It sounds like you ran a line directly from the tank/filter to the fuel rail...

That's correct.

Here is my setup. Fuel safe gas tank, Pro-M fuel pump hanger, aeromotive 340 LPH pump, SS flex -8AN supply and -6AN return. The -8AN runs from the hanger to a Y fitting at the back of the engine where two -6AN lines go to each side of the Fore Innovations fuel rails. The rails separately return to the aeromotive regulator via-6AN lines and a single -6AN line runs from the regulator back to the tank and connects to the hanger. I also have 47 lb injectors.

I don't know about the Gen 3 Coyote but my Gen 2 uses a 190 LPH in-tank pump with regulator and filter combo on the gas tank, which allows for a very short return line and a single, standard size, SS flexible fuel line directly to the fuel rail. Simple to install, inexpensive and provided more than enough fuel to produce 401 RWHP. Mark at Breeze was very helpful in helping me to simplify this portion of the build. You might consider asking him what your Gen 3 would require.

Will do, thanks!

All the advice in the world is nice. But if in doubt follow the Ford Performance instructions. :o For the Gen 3 Coyote, very clearly says "Set regulator to maintain 65 PSI delta fuel pressure..." and "Fuel pump requirements: 165L/hr minimum at 65 PSI." Both of these are higher than the Gen 1 and Gen 2 where the regulator is supposed to be at 55 PSI and the fuel pump requirements are listed as 155L/hr minimum at 55 PSI.

Why the difference? Not stated. But obvious reasons are the Gen 3 makes quite a bit more power than the previous versions. Plus the addition of direct injection. There is a direct injection pump on the engine (which puts 2,000+ PSI to the injectors, crazy...) but it has to be fed too. I personally wouldn't use any setup that doesn't meet the Gen 3 stated requirements.

Thanks everyone for all of the great feedback. Really great catch initially by Toadster and feedback from everyone. Appreciate the support. Here is the new setup. I think this is everything but would appreciate it if you would give it a quick once-over. Thanks in advance!
