Hi Guys need some help, I ready for a return system and although I'll be around 750whp, I want room to grow. I like that the fore system has a check valve, but the lethal system seems to have better wiring and comes complete. Also the Lethal system looks like it is a couple of hundred cheaper after the fore add ons make it a comparable kit. Anyway my questions are;
What are the differences between the 2 kits?
Can you add the fore check valve or even the stock valve to the lethal system so it doesn't run all the time?
What system did you choose, why? Please no because a run a 9 sec 1/4. Both systems will do that, any actual advantages?
Thanks for your help as always!

Had the same choice and went with Lethal since their kit was on sale last month. I just bought a check valve from Summit and added it to my feed line, wasn't a big deal.

- Their PTFE/stainless fuel lines have a black coating which is nice, looks better and doesn't scratch paint
- Lines are pre-cut and pre-assembled.
- Wiring harness w/ relays is super easy to pre-made. I prefer a relay harness vs a fuel controller personally.
- Duel fuel regulators (not sure if the L2 fore is single or double)
- -10AN feed, probably overkill but still an upgrade.

Did you come right off the hat, with something like this

or just splice into the line with a double male valve

I attached it to the fuel filter then a male -10an. Pretty sure it's exactly how Fore does theirs too.

To be honest, with a triple pump setup and it priming as soon as I open the door... I don't know if I even need the check valve. I am thinking about taking it off and see if there is a difference.

Let me know if you have any starting problems when you take the valve off. I was thinking of not only running the check valve but seeing if I could rewire so the pump doesn't run until ignition.

I have the Lethal Triple Pump Fuel System for the Whipple, nothing added outside of what was supplied and car starts just fine. Had it been an issue I'm sure Lethal would have addressed it.

I personally don't think you can go wrong with either fuel system.

Yep, my experience as well. I got everything under 1800 out the door. You're not going to get a Fore triple pump and dual regulator system with PTFE for that. I think the Lethal kit has some nice QoL features with their kit that makes it better than Fore.

Under $1800 for the full system? That is a great deal! Did you call in? They don't seem to respond to pms

They had a sale a month or two ago that was about 15% off I think, and stacked another site wide coupon code on it. Was hard to say no to that, it's why I ended up with it over Fore. I am happy with the decision. My car is an Edelbrock TVS2650 setup, so I didn't need fuel rails since the blower came with billet rails already.

Same with Whipple

Thanks for looking into one of our Fuel Systems, we appreciate it. We wanted to make sure our kits alleviate any questions are issues when installed and make sure everything you need is there when installing. Some people like mentioned above will add or change the system to their liking but that’s more of a personal preference to do so.

750 wont be an issue as long as you have injectors that’s keep up and if you want to up the power you can always add a third pump down the line which was another feature we wanted to make sure was available for kits.

i believe Blake has replied back to your PM and will get you squared away. Thanks again ☠

The difference with fore, is they are a fuel system company, everything is 100% made in house and quality and support is bar none. it's not 2nd hand parts pieced together for more profit.

their warranty is unparalled and they stand behind everything

They are a family owned and run business, and simply incredible to deal with

feel free to hit me up with any questions on a system

No other system comes close to the quality and customer service Fore Innovations has.... everything else is a “knock off!”

Sorry if this a stupid question, but if Fore is 100% in house, who manufactures the Lethal system? I'll admit $1800 in enticing, even if it's only once or twice a year.

And to a person that's never done fuel system work, how much easier is the Lethal system to install?
