Up until now, if you wanted to upgrade to an in-tank fuel pump in your 1963-1972 Chevy or GMC Pickup there were no easy answers. Nobody makes an EFI replacement tank for the awkward behind-the-seat tank location and because of its shape a retrofit in-tank module was not going to work either.

This new frame-rail mounted EFI Fuel Tank gives you the basic components to have an EFI fuel tank mounted below, on top of, or in-between your fuel rails. Multiple mounting styles and locations are possible.. Required mounting hardware must be selected and sourced by the installer. Comes standard with a 255 LPH EFI-style fuel pump with return fuel fitting or choose from other fuel pump options.  Tank size is 28 x 20-1/2 x 9-3/4 inches not including mounting tabs, 32-1/4 x 20-1/2 x 9-3/4 inches with. This 18 gallon fuel tank is made for gasoline only (No E85, no diesel.)  Full Detailed Specifications Below!

Choose from Tanks Inc® or Holley® Sniper EFI™ brands.  Your choice of through-bed-filled tank with hose, through-bed-filled tank with aluminum cap, or side-mounted filler neck.  All require modification of either the bed or truck side for use.  Your choice of early GM fuel level sender (0-30 Ohms) or late GM fuel level sender (0-90 Ohms).  As far as we can tell, GM used a mix of early-and-late senders from about 1964-1966.  Recommend that you employ an ohm meter to identify which sender your gauge expects.

A Word About Fuel Pump Selection

We offer a broad range of fuel pumps for your EFI fuel tank system. Select a fuel pump that flows as much fuel as you require. Remember that lower-flowing pumps tend to be quieter and can have somewhat longer life expectancies. All of these pumps are manufactured by Walbro / TI Automotive, who ranks in the top 5 OE-quality fuel pump manufacturers in the world. You will not find a better fuel pump at this price and quality combination. Some notes:

• The 255 LPH Pump is the BEST choice in most cases and can feed up to 650 HP at 60 PSI (Naturally aspirated, Gasoline.) If that is you then pick the 255.
• The 255 LPH pump is a gerotor pump and is not PWM Compatible. This means FiTech EFI System owners should be sure to disable the PWM feature if selecting this pump.
• To estimate how much fuel flow you require multiply your maximum expected flywheel horsepower by .38 (naturally aspirated engines) or .47 (boosted or sprayed engines). Example: If you are hoping to make 650 flywheel HP on motor only then you will need 650*.38 = 247 LPH of gasoline.
• Pumps flow is rated at 43 PSI. To estimate the flow at 60 PSI multiply the rated flow by 90-95%.
• The 190 LPH pump is a low-pressure pump that works directly with GM TBI applications and can work with carbureted applications if properly return-style regulated.  It will not work with standard EFI as it ceases to flow fuel at a bit over 30 PSI.
  
• Pumps flowing 340 LPH and above are DC/SS pumps and are PWM compatible.
• The 430 LPH Pump is E-85 Compatible but these EFI Tank Systems are approved for use with GASOLINE ONLY. Use your best judgement on how to proceed with that.
