AutoTech High Volume LF3/LF4 HPFP Internals Kit
We all know that the fuel system on the ATS-V is one of the weakest points in the entire drivetrain, which is why we've worked diligently to release products like our larger fuel cam lobe and upgraded fuel pump assembly. Now AutoTech has released a kit to increase the volume of the high pressure fuel pump, helping to alleviate the fuel system problems we've continued to address.
This kit replaces the existing piston and cylinder in your OEM high pressure fuel pump. AutoTech claims an increase of 36% in volume, we will do our own in house testing once they have been received in and report back with numbers. Regardless, this kit will pair perfectly with our existing 2 fuel system upgrades, letting you run increased amounts of ethanol without the extra cost of big bore HPFP's that other companies sell. Fully compatible with stock cams or aftermarket cams.
Competitors will claim that you need to replace your costly ($300) factory fuel lines while doing the HPFP upgrade, we know that this is not necessary and that your factory fuel lines will work perfectly fine after disassembly.
Note: The fuel pump disassembly tool is needed for the job, tool can be found here.
This kit is currently up for pre-order. Kits will ship end of December 2020/early January 2021.
