Pontiac V8 EFI Solutions- Master Series
One Part Number, Whole Conversion — EFI Solutions- Master Series for Pontiac V8s
The EFI Solutions Master Series is Butler's answer to the part of a carb-to-EFI conversion nobody budgets for: the fuel system. Each kit pairs a complete EFI system with a factory replacement EFI-ready fuel tank, an in-tank pump, a line kit and a regulator, so the car goes from mechanical pump to injection in one purchase.
Kits are built around Edelbrock EZ-Street, Edelbrock Pro-Flo 4, FiTech Go EFI 4 and Holley Sniper 2, plus a Sniper system-choice kit. Two tank-only kits cover cars that need the fuel side first.

More About EFI Solutions- Master Series
1. What a Master Series kit covers
The EFI system is the part people shop. The tank package is the part that decides whether the car runs right.
| The tank | A fuel injection ready factory replacement tank in galvanized steel, powder coated silver, with EFI style internal baffling and an extra large internal fuel tray to prevent pump starvation. It looks like an OE tank once installed. |
| The pump and sender | A GPA series in-tank pump and a 0-90 ohm sending unit, both recessed into the tank so no modification to the car is needed. The Sniper system-choice kit steps up to a higher flow pump. |
| The plumbing | A stub neck to attach to your original filler neck with the supplied 2 in. ID connector hose, a choice of line kits, and a billet Pontiac fuel pump block off plate for the hole the mechanical pump leaves behind. |
2. Choosing the EFI system inside
All of these kits solve the fuel supply the same way. What changes is the control system sitting on the manifold.
| Edelbrock EZ-Street | Self-learning four-barrel throttle body on a 4150 flange, supporting up to 650 horsepower, tuned through a Bluetooth app. |
| Edelbrock Pro-Flo 4 | The multi-port option for Pontiac 326-455, including the EFI intake and a plug-and-play distributor. Choose this when the intake is coming off anyway. |
| FiTech Go EFI 4 | Throttle body mounted ECU with built-in pressure regulator and spark control, rated for engines from 200 to 600 HP. |
| Holley Sniper 2 or Sniper system choice | Sniper 2 for the current four-wire conversion, or the system-choice kit when you want to specify which Sniper or Super Sniper body goes on the engine. |
3. The two tank-only kits
Not everyone needs the EFI system today. Sometimes the tank is the job.
| In-tank pump to EFI | Converts a carbureted fuel system to EFI ready, with a full -6AN line kit and a billet bypass EFI fuel regulator. Works with most throttle body systems including Holley Sniper, FAST EZ, Edelbrock Pro-Flo, FiTech, Aces and MSD Atomic. |
| In-tank pump to carb | The same EFI-ready tank and high pressure in-tank pump plumbed for a carburetor, with an Edelbrock carbureted bypass regulator. It kills the mechanical or inline pump now and leaves the switch to EFI as an easy change later. |
If the car is apart, do the tank while it is out. That single decision is what separates a conversion that idles correctly on a hot restart from one that fights you forever.
