During my 4A-C to 4AGE engine conversion in my Australian AE86 sprinter it came time to upgrade to fuel system to be able to meet the new demand for fuel. Being a naturally aspirated engine beforehand there is no in-tank fuel pump, only a mechanical fuel pump on the engine (driven by the camshaft). Japanese AE86 Sprinters on the other hand came from factory with a 4AGE engine and the EFI tank to suit. I had 2 options, find a tank from a Japanese AE86 (Can be expensive) or install my own generic lifter pump setup inside the tank. I opted to use a VK/VL Commodore lifter pump inside the tank. (This setup could also be adapted to other non efi tanks (KE70/AE71 etc).
(Lifter pumps are designed to suck the fuel, not pump it at a high pressure).
To start with I removed the fuel line setup from the top of the fuel tank.
The Lifter Pump will be fitted where the old in-tank fuel filter is, it can be removed easily.
The Lifter Pump I'm using is from a VK/VL commodore
Here is what the Lifter Pump looks like with the fuel filter on.
I had to hacksaw a fair bit off the end of the fuel pickup line to get the lifter pump to sit where it needed to in the bottom of the tank. A few test fits and I clamped the lifter pump to the fuel pickup line.
