Fueling - High Pressure Fuel Pump Upgrade

This is a bolt on larger mechanical fuel pump for your direct injection LNF, LHU, or LDK engine. This is an absolute must have for any LNF/LHU wanting more than 400whp on E85. We have tested this pump to well over 500 WHP using straight E85, without any indication of a drop in rail pressure all while using the early prototype modified fuel lobe cam, which only had around half the additional 'lift' when compared to our current off the shelf cams.

When coupled with our ZZP cams w/ fuel pump lobe, and opel injectors, expect enough fuel system to support over 600 WHP on straight E85!

Dont be fooled by others selling off the shelf pumps with an adaptor plate. They have bent, and kinked the inlet line, which is restrictive, and use a wimpy spring which causes the pump to 'float'. ZZPerformance has developed a billet inlet adaptor that clocks the fuel inlet hose to the proper location which not only looks fantastic, it WORKS. We have also developed a new spring, specific to this application to help combat the float issues that others are seeing.

Fits Cobalt SS, HHR SS, Pontiac Solstice GXP, Saturn Sky Redline, and Buick Regal.

Horrible customer service talking on the phone is useless and calling ppl liars and seems like scamming to me in my case for a pay day it’s sad a company would do that

Overall amazing, but....

As for the quality of the part, hands down can’t get any better than this! Simple and clean look and also frees up just a tiny bit of space on top of the intake manifold. But the only issue I had while installing this part, besides me trying to retain the factory pumps shield/ charge pipe bracket and cutting it to pieces, is that the instructions that are provided show the pump being installed on the head without the intake manifold on there so I had to file a bit of material off of the intake runner in order to rotate the pump into its final position to bolt it down. Could also save the consumer the hassle of including a new gasket also instead of offering separately or by purchasing from a dealer. But overall I love it and ZZP’s service has always been great!

Upgraded HPFP

The billet improvements and welds look clean and high quality, as well as the spring upgrade. Have not installed yet but should be the same as the stock pump, and easy with the instructions provided. High quality stainless bolts as well. Will update if anything changes during install.
