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.
Here is a shot of the Lifter pump mounted to the fuel pickup line.
This is the VL Commodore In-Tank Lifter Pump assembly I bought from the wreckers for $55.00, I bought this for the wiring connector and the wires. I Decided against running normal wire inside as I don't know how long it would last before the petrol chewed it away. An auto sparky I taked to said the same thing I was thinking, use the wiring out of another in-tank setup.
Here is a closeup of the wiring connector that I removed to install into my setup.
Another advantage of using the wires from the VL lifter pump setup is that the connectors for the lifter pump wiring are already crimped and properly insulated.
Here is a photo of where I drilled a hole in the AE86 fuel line setup for the VL wiring connector to go.
