I've got a built Stroker Motor, Kenne Bell Mammoth pumping 25psi and making 680 RWHP. For a primarily street driven car, with limited track use, what are you guys using as a step up to the GT500/Dual Kenne Bell BAP.

I'm looking at the Fore Triple Pump Hat, but was trying to figure out which style to go with (Return Style or Returnless).

I was thinking of the returnless and hook up a hobb switch to the third pump for WOT use.

What are you guys using??

A returnless system would be just fine for you. But seeing how your in FL, emission wont be a issue there so it all comes down to how much power are you looking for. A triple return system will allow some serious power in the long run. But for a street driven car with some track time, a returnless would be nice.

I would absolutely suggest you to go return but properly designed so it would be street friendly, also, you can't use a returnless config with a switched pump.

My only concern with using a Return Style setup is heating up the fuel. With my Aeromotive setup on my '97 Cobra (making 740RWHP), I had a Fuel Controller to modulate the voltage to the pump, but then went full voltage to the pump at WOT.

I'd like to keep the system as simple as possible since this is primarily a street car. I do understand that I'm now hitting a point where there's going to be some sacrifice.

So the idea with the Hobbs Switch on the third pump wouldn't work at all?

Properly designed? Could you please eloborate?

With a pre-rail regulated configuration you reduce fuel warm to the minimum. In this case you don't need a "duty-cycler" (It does not modulate voltage because gerotor pumps won't last under lower voltages so it switch voltage line to obtain the same control) that the one you have for your A1000 (guessing you have one) because internal walbros do not overheat as the aeromotive's

You can use a hobbs switch with the GSS342 but not on the GT pumps because they do not have check valves as the walbro's and when shut off they become a return line to the tank.

There is no sacrfice to make, the return system properly designed just works and you can make the wiring as you wish, for example I have two and I used an SoS switch board where I can turn both them on, off, either one and choose which one to use the hobbs switch so I can alternate them at wish.

It has everything you need, just add injectors. This is close to the system ill be running but with 205lb injectors and E85 and looking to make 800+, then 1000+ with new motor!

Call and talk to Jared or Matt, tell them Alan told you to call. Plus they are a supporting vendor of the site!

This is the same system I put in my car this year but I only have 2 pumps set up for now. Works flawlessly. The pumps are a little noisy until the car fires up & them you cannot hear them over the engine/exhaust sound.

If I'm already using GT500 Pumps in the car right now, can I use those pumps and by one more for the Fore Hat, or do I need to buy different pumps?

Someone mentioned to me about using the GT500 Pumps from the GT500 setup, and buy one more and I'd be set, but if I'm going return style, isn't that a different kind of pump?

Return and returnless are different type of pumps.

Returnless pumps can be run in a return setup but remember they do not have a check valve. I have about three customer cars that with FGT and focus/gt/gt500 pumps in return config.

But if I were you I would put the whole GT500/Bap system appart and sell it out instead and install proper pumps.

And that is why I asked. I don't know why I was told to use those.

Which pumps would you recommend Lito? Walbro or GT? Because aren't the hats fuel pump specific?

Yes, Fore hats are pump specific, FGT are thinner than GSS342's.

If going return use GSS342's if returnless, FGT.

When I commented the return sys with returnless was crazy adaptations done here, one cobra hat on a 2002 with 2 FGT's pump and modded for a return line, a GT500 hat with a return line in a S197 and even a Fore complete returnless install where we received a faulty MDM that we decided switch it to return, all worked out well and some still do today. But if it was my car I would do it right, with the proper install and the right pumps.
