EZ-EFI v.1 up to 650hp
EZ-EFI v.2 up to 1200hp

 

I agree with diehrd, why complicate things with two fuel pumps?

Here is a post I recently did that showed what I did, as well as another option from Aeromotive:

Very nice. Thank you. Yes a little fore thought on my part would have saved me time and $$$. New stock tank, lines etc.

 

Okay, some pics as promised.

1) regulator: I custom made an aluminum bracket that mounts the regulator off the back bolt of the throttle body on the passenger side; it is tucked in nice and low and would clear any drop-base air cleaner base







2) fuel lines: I am not sure exactly what specifically you want to see, so here is a description. I ran an additional 3/8" hardline down the passenger side frame for the return. All the lines at the throttle body are also 3/8" hard line. For the rear hard lines to tank and at the front for the frame to throttle body connections, I used -06AN hose. The fuel tank also has 3/8" hard lines exiting it. All the lines are stainless steel custom bend and 37 degree flared by me. If there is a specific pic you are looking for, let me know.

3) control unit: not much to see with this, I used the cable that came with the kit as well as an extension cable to keep the unit under the passenger seat. I also have the control unit connected to key-on power so it is on when the key is on.

4) ECM: while this location might not work for your later car, I mounted mine behind the driver's side grille.








Hope this helps.

 

Would the C3R emblem above the grille stand for C3 Restomod? Also, can't quite make out the words below the C3R in the photo.

Impressive installation of the various components ... work usually done by the high bucks custom shops.

 

EZ-EFI 1 is 600hp... I'm running the EZ efi 2.0 good to 1200hp:-)

Yes thank you, ... where did you mount your filter and 3-hole pressure sensor?

 

7t2 that's some really nice fab work! Well done!

 

EZ EFI is 650hp uses 4 80lb injectors .. 600hp kits use 4 75lb or less injectors.

 

Pauldana - wanted to let you know that FAST had "some" issues with the 2.0 system as many of us had signal interference no matter how isolated we kept the wires. My car would run and then stall/comm error randomly. Nothing that was tried or changed made a difference so I ended up sending everything back and upgrading to an XFI system. I have been told now that FAST is installing some sort of filter or isolator in the ECM to help with these signal issues on certain vehicles. I guess some are able to send their ECM back for the update? You might want to call and ask before getting too far along but good luck because tech support is somewhat of a joke depending on who you get on the phone.

 

Hey Paul, I mounted the filter right on the tank:



This is what I did for the tank:

I am not sure what you are referring to as the "3-hole pressure sensor", it must be something that is part of the EZ-EFI v.2 kit.

 

Been Reading this Thread, Do not Believe The 1200 HP F.a.s.t Claims it will support. At least with the externally mounted Pump/ fuel system they supply. I pre ordered the complete 2.0 with external pump kit. Ordered it in June at the HR power Tour in Arlington Tx. I am in the middle Of a resto type build on a 70 convert.

In Nov My motor was on Dyno at Long Racing Engines in Irving Tx, highly built motor and it is a 540 BB . I am also using The FAST dual sync dist to be able to control timing from the handheld. Fist thing I will say is the system is just flat cool ! This was also Longs first experience with the 2.0 and all involved was impressed with the 2.0 . and it worked great, after playing wit the dist. a bit, it fired right off. But after a few pulls It would just flat run out of fuel at 62 to 6400 RPM . The fuel pump would just not keep up. There is just no way that small pump and #6 Fuel line will support a high HP BB engine. To make long story, short ended up spending about another grand on sump for tank, Areomotive pump/filters #10AN and #8AN line, fittings and such.

Called Fast about it, They did not seem surprised and had no solution and it seemed to to me the fellow on the phone seemed to have heard this before. But they did offer to take the pump , lines and such back and refund my $350 or so spent on the fuel supply system. I do also see they now offer a fuel pump system similar to what I ended up putting on for about 900 bucks without lines.

Only posted this as to my experience and of course yours may be different, but think long and hard about there externally mounted pump kit offered with it, at least on a high HP Build. I would think It would probably work ok with a 500 to 650 HP motor. I will be installing motor later this month and I will post again after having it on the road a while.

 

Anybody have any experience with this low-pressure in/high pressure out sump tank Edelbrock makes for mild engines? (350ish horsepower)

 

I never considered the in line pump for my EZ system 1.0 . It would have to draw gas out of the tank and most electric pumps not all but most push fuel a lot better then they can pull it.

So I am not surprised you had to go in tank with a fuel pump.
