These fittings fit directly onto the SEP 044 in-line fuel pump and convert the metric pump threads to AN threads for ease of use.

Genuine hard anodized aluminum Sh*tbox Supply fittings prevent back flow into the fuel pump. These ensure fuel pressure is not lost in dual pump situations where one pump may flow more than the other or when one pump is wired to activate under specific conditions such a boost referenced switch or TPS settings.
