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.
