the specifics depend on how and where you want to set it up and which model you have and the size fittings you use...but in general you may need:
- three (3) AN fittings for the SARD rrfpr (inflow from the fuel rail to the sard rrfpr,,,, outflow line from the sard rrfpr to the fuel pressure gauge to set the desired pressure, this could be permanent or temporary gauge installation,,,, outflow/return from sard rrfpr to the fuel tank )..i think i used 6AN fittings
- one (1) AN fitting/adaptor for the fuel rail
- vacuum line (from the sard rrfpr to plenum)....length is dependent on where you install it
- fuel hose (from the location of the sard rrfpr to the return pipe on the bulk head,,,and from the fuel rail to the sard rrfpr)...length is dependent on where you install it...size is dependent on the size of the AN fittings used
- it comes with a small brace, but you may need to build another brace or use one you have laying around,,, depending on where you position the sard rrfpr
i bought my entire kit and extra fittings from rhdjapan many years ago, but i suppose you can get them from other places---ebay, amazon, sales section, wanted section, performance shops, etc.
