Those other build threads were pretty long, so I figured why not consider this a new build v2.5

I decided to overhaul quite a bit of my setup... motor is still the same iron 365ci 4-bolt w/ LSA heads and LS9 gaskets

- swap the F1A-94 for a new F1X
- replace my single walbro 450/stock bucket with a Fore triple pump (Walbro 450 + two AEM 320e) + keep my external magnafuel 4303
- redo my fuel lines with a -10 feed split to a -06 for each rail and rail mount my regulator with a -08 return + 3/8" feed line return
- replace my stock radiator with a RSD cut down radiator and spal fans
- beadlock my 15" Weld RT-S and try the new MT ET Street R tire
- custom oil cooler
- replace both rear hubs since the wheel studs were getting worn out and prone to stripping

Fuel system should fix this:


Should give some clearance for the F1X


Left the cooler off last year to help the car warm up as it got colder in fall, now its time to get it installed


Starting to dig in...


Fore stuff is really nice quality


The Fore setup to reuse the level sender was really nice





I figured I'd post a few pics of how the tanks and transfer tubes go together in a C6 vette... it sucks. I replaced all my internal lines and swapped the lingenfelter bypass for the Fore piece:











The factory harness needs to be split up so the level sender wires can be attached to the Fore hat wires. The power needs to go to the FC3 controller to trigger pump #1 to come on like the factory pump. Ground just goes to frame ground.



Routed my fuel lines. -10 feed, -08 return, both with unions to make disconnecting and dropping easier if needed.



Wiring pretty much done, gonna clean the FC3 up a little when I secure it after testing






Wheels getting ready to go





Picked up the F1X too



Rail side came out pretty clean... The magnafuel regulator is pretty huge. I'm running both my old stock feed return line as well as a -08 retun (which was actually my old aftermarket feed line).




Need to button up the rest of the fuel system and sort out some odds and ends and then I can fire it up and test the pumps.

Fore makes some top notch stuff. Can't wait to see what that F1X does for you. May need to see what that F1A-94 does for me. See ya next week dude.

What are you going to be spinning the f1x to?

turbotuner20v

4.5" blower pulley, 8" balancer, ~7,000rpm

I'm going to see what 67,000 does

Do you have a part number for the fpr?

Thanks

85psi max is nice and -08 all around

Nice updates. Always like what you do. Looking forward to seeing what this thing does now. That Fore stuff looks amazing.

Fuel system is done and tested with no leaks. Main fore pump kicks on to prime like stock and the other 2 pumps kick in when 12v is applied to the trigger port of the fc3. Level sender works for the 5 gallons. Magnafuel kicks on too still via seperate hobbs + toggle switch. Toggle makes it easier to quickly mix fuel plus I know I'll always have 1 big *** pump I can manually control to run the car if needed.

The back half is a little cluttered given its basically 2 full fuel systems, but that's what the fender liner is for.

Gonna wait till morning to start it up to avoid pissing off the neighbors

I'm a bit confused on the fuel system. What again are all those pumps for?

turbotuner20v

Think of it like 2 fuel systems

Fore in tank has:
- walbro 450 main pump that ecu controls to prime and run
- 2 AEM 320s that come on at 4psi

External sump has:
- magnafuel 4303 that comes on at 4psi

So in boost 4 pumps are running.

Maybe overkill, but I already had the external magnafuel, so i figured why not leave it in

turbotuner20v

Started it up and took it to my tuner to iron out the fuel since it's sending so much more. Cars running well, fuel level senders are working across both tanks, siphon system is working, etc.

Realcanuk

Glad its working well. You are giving me pump envy... I only have 3..... LOL

Did that single walbro work out good with the F1A setup.

turbotuner20v

It was always a magnafuel 4303 + Walbro 450. It ran a little lean up top on E85 with that combo, but it had more to do with a fuel siphon system issue dropping pressure and making the walbro less effective.

Ok i was wondering about that im trying to plan my fuel situation for an upcoming f1a build, what would you recommend, now that youre changing things up.
