<p>202.61.138.253: </p> <hr /> <div>During my 4A-C to 4AGE engine conversion in my Australian AE86 sprinter it came time to upgrade the 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).<br /> <br /> (Lifter pumps are designed to suck the fuel, not pump it at a high pressure).<br /> <br /> <br /> ----<br /> <br /> To start with I removed the fuel line setup from the top of the fuel tank.<br /> <br /> <br /> [[Image:Post-6-1128150134.jpg]]<br /> <br /> ----<br /> <br /> The Lifter Pump will be fitted where the old in-tank fuel filter is, it can be removed easily.<br /> <br /> [[Image:Post-6-1128150277.jpg]]<br /> <br /> ----<br /> <br /> The Lifter Pump I'm using is from a VK/VL commodore<br /> <br /> [[Image:Post-6-1128150456.jpg]]<br /> <br /> ----<br /> <br /> Here is what the Lifter Pump looks like with the fuel filter on.<br /> <br /> [[Image:Post-6-1128150575.jpg]]<br /> <br /> ----<br /> <br /> 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.<br /> <br /> [[Image:Post-6-1128150788.jpg]]<br /> <br /> ----<br /> <br /> Here is a shot of the Lifter pump mounted to the fuel pickup line.<br /> <br /> [[Image:Post-6-1128150962.jpg]]<br /> <br /> ----<br /> <br /> 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.<br /> <br /> [[Image:VL Lifter Assembly.jpg]]<br /> <br /> ----<br /> <br /> Here is a closeup of the wiring connector that I removed to install into my setup.<br /> <br /> [[Image:Post-6-1128748835.jpg]]<br /> <br /> ----<br /> <br /> 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.<br /> <br /> [[Image:Post-6-1128748921.jpg]]<br /> <br /> ----<br /> <br /> Here is a photo of where I drilled a hole in the AE86 fuel line setup for the VL wiring connector to go.<br /> <br /> [[Image:Post-6-1128754801.jpg]]<br /> <br /> ----<br /> <br /> Underside shot of where I drilled the hole in the AE86 fuel line setup for the VL wiring connector to go.<br /> <br /> [[Image:Hole Drilled.jpg]]<br /> <br /> ----<br /> <br /> The VL In-Tank wiring connector removed from previous setup.<br /> <br /> [[Image:In Tank Connector.jpg]]<br /> <br /> ----<br /> <br /> The VL In-Tank wiring connector installed / wired into the AE86 fuel line setup.
