    Works great. I had to put some o-rings on the inlet and exit line nipples to keep them from leaking. Had it for over 2 years now and still going strong.

    I purchased one for my S13 SR20det swap. I'm pleased with the quality and the gauge and adjuster work perfectly. It takes all the fury of my 255 lph fuel pump with ease. AFR's are very stable.

  7. fits on bluebird sr20det!

    Just put this on my 200sx w/ BB SR20DET. Noticeable response as soon as we test drove the car. Very easy to install and I'm not mechanically inclined at all. Just research to know exactly what psi you need to be running.
