What we did and what works best is to call fore and explain your car and setup and they piece it together.

The pumps are now big enough and can flow enough without the BAP.

Does the fuel get warm with pumps running all the time or did you install a hobbs switch or something? I saw some thing you guys mounted in the trunk. I guess that tells the other pump to come on at boost right?

@@dy-no-mite9365 yes, the fuel will be warmer having traveled to the engine and back. There is a boost line that signals an increase of fuel pressure when it senses boost (which is why you must attach it to a boost vacuum line. Some people put it on a regular vacuum line and ran lean

@@dannyjohnsonsgarage thanks for the insight my good man

Thanks!

The kind of fuel is the key. E85 needs more fuel flow. In this case we are doing pump gas so we didn’t need much. For 800 hp it is most likely you will need E85. I would go one step bigger on the kit with the feed line (this kit uses the stock feed line and then adds a return line). You’ll also want bigger injectors. A 3rd pump may not be necessary, but I’ve seen people add a 3rd that comes on only when needed

The cobra tank is sumped, but pretty similar otherwise. I’m sure fore would be able to tell you if you need it for a GT tank or not

I got most of it, but my brother had finished a lot without me kzfaq.info/get/bejne/j51ndLp7u9_eY6M.html

It may have to do with the tune you have.

No, my brother called fore and they put together the kit he would need. They saved him money telling him what he would or would not need for his setup.

Yes, precisely. The fuel pump driver module (fpdm you saw removed) typically controls the pumps when you first turn the key. You hear a small prime and that’s all. With the return fuel system it will make the prime sound but not stop since the pumps are flowing from that moment on. Some people keep the fpdm to override that, but it would need to be tuned by someone who knows how to make that all work.

@@dannyjohnsonsgarage I also have the same type of fuel regulator setup you showed next to my supercharger above the fuel rail with a pressure gauge on top of it so I suspected there is an upgraded system. Whether it's a return system or not I am unsure. I'll have my mechanic check to be sure. I found out about the pumps when I was running a diablo i3 tuner and when I tried to load an upgrade the tune failed because the constant running pumps had drained all the power from my battery! So now in order to do anything like that again I would need to disconnect #14 fuse(box under the hood) for the pumps so they are off when loading a tune. I am in no rush to mess with the present tune though because the car is running great and it already has all the engine mods I wanted in the car and the tuning was done by a very highly rated group...ProDyno out of South Carolina, so...don't mess with success! lol Great video Danny.

@@dannyjohnsonsgarage Follow up...After some closer scrutiny, I've have been able to confirm that my upgraded fuel system is indeed a full return setup. Makes sense since all the required components are there. I just had to confirm the return line which runs off the regulator. Now I understand why my Cobra runs so well! lol Love your videos Danny!

I’d contact Fore and see if they have other options, but I’m pretty sure you’ll need the controller

Yeah I emailed them yesterday. Hard to get answers.

The tuner sends a “startup tune.” On that it will run fine as long as you don’t go into boost.

We left the evap installed

You take off the stock fuel rail pressure sensor and replace it with the new system's fuel pressure regulator. It's also very common to have a fuel pressure gauge installed on the new regulator so that's why you sometimes also see a fuel pressure gauge there.

It is close to the budget kit, but it was ordered by calling fore and them piecing it together

The benefit is more fuel flow with less trouble. By comparison my cobra is at 600rwhp on stock pumps with a boost a pump. It does ok, but it’s not perfect with the pprv valve, and managing the returnless off and on signals. Where the car in the video is 650rwhp with a bigger supercharger and more room to grow, it’s just a better, more simple setup. He also went with 80 pound/hr injectors

@@dannyjohnsonsgarage I'm currently sitting stock (power wise) and as such don't face many of the issues you guys who are making more power do. Knowing my obsessiveness with my car once I start adding power I won't stop till it becomes pretty darn unreliable. *crazy smile* I'm currently working on suspension and braking mods before I even get into adding power. Cars gotta be able to handle the power and stop it right....lol. I like to watch you and your brother and couple select other Cobra guys for advice, I trust y'all. I bought it 4 years ago from the original owner with only 6k miles on it. I'm done babying it now so time to have some fun. I'm kinda curious about the boost-a-pumo...useful when stock?

Yeah, I still need to edit it. It’s pretty simple. Replace the fuel rail pressure sensor with the regulator, make sure the screw in the bottom is in with some pipe sealant and won’t leak, thread the other fittings just like in this video, and usually they have the regulator already set for pressure. You want to make sure the vacuum line goes to a boosted vacuum line so it will have the pumps give more fuel with boost. If not it won’t know enough to increase fuel pressure

@@dannyjohnsonsgarage well I hate doing projects unless I watch a video you do on it so hurry up haha.

@@dannyjohnsonsgarage God i hate the frps. Its the only thing in my cobra I worry about. Blow one every two years or so even with the kennebell disc. Might have to look into this system.
