![]() ![]() They eliminate the need for an external surge tank which would otherwise be needed when running a fuel cell, making it a perfect alternative for fuel-injected systems. The Nuke Performance AluCell fuel cells are suitable for carburetor-based fuel systems and with the integrated CFC Unit from Nuke Performance.

Peace” Jay R.Ĭopyright 2010 : Engine Basics.AluCell Aluminum Fuel Cells, a lightweight and affordable fuel cell combined with the Nuke Performance drop-in surge tank, the CFC Unit. So much mis-information on forums, good to read some solid info. Thank you for showing the REAL easy way, and saving me some money.” Joe Sĭon’t have any questions, just wanted to say thanks for putting this info out there. Info from every other site I looked at, only said how to do it using costly special tools. “Thank you, for the info, on your site, on how to remove valve springs, and install stem seals, using normal shop tools. **TO SUBMIT AN ARTICLE TO ENGINE BASICS PLEASE CLICK: CONTACT US!

This tank is made from 3 inch, 6061 T6 tubing. ![]() This tank has 3 lower fittings for twin pumps plus a drain fitting. ![]() Usually 1/8 NPT or 1/4 NPT fittings are used but AN type fittings can also be used depending on your plumbing preferences. Threaded bosses are welded to the top and bottom caps or sides as in the example below. A long tank allows any trapped air to rise to the top so it does not enter the high pressure pump. The tubing is usually 2.5 or 3 inch diameter and. 5 to 1 liter in capacity, made from either steel or aluminum tubing. Usually only one fitting is used on the bottom of the tank for feeding the high pressure pump. Most tanks will have three fittings on the top, one for feed from the low pressure pump, one for fuel returned through the fuel pressure regulator and one for the return back to the main fuel tank. The schematic below shows a common setup: (click for larger image) From here, if the surge tank is full, fuel is returned back to the main fuel tank. Fuel not used by the engine is returned from the rail, through the fuel pressure regulator, to the top of the surge tank. The fuel gravity feeds into this pump and goes to the fuel rail. A high pressure EFI pump will be mounted below the surge tank. Often the stock electric pump can be used. Fuel is piped to it by either a stock engine driven mechanical pump or a low pressure electric pump. Usually the tank is mounted in the engine compartment. The surge tank stores a small amount of fuel for the high pressure pump to pick up if flow from the main tank is interrupted for any reason. This is also useful on many stock EFI cars which have poorly baffled tanks. To convert some carbureted vehicles to EFI, we recommend fitting a fuel surge tank to avoid fuel feed problems, especially during hard cornering. ![]()
