Gen4 3sgte SW20 Fuel Line

The Gen4 is one of the best factory 3SGTEs to have. Treat it like one. If you've got a Gen4 in your SW20, you're running one of the most developed factory turbo 3S engines Toyota ever built — VVT-i, a great-flowing head, and the kind of tuning potential that made the Caldina GT-Four a JDM legend. It deserves a fuel system that doesn't bottleneck it. We built this line to match. Same proven hose and fittings as our popular 20V 4AGE line, sized and routed for the Gen4 3SGTE in an SW20 chassis. It's a 3/8" (-6 AN) PTFE-lined stainless steel braided fuel line, rated at 2,450 PSI working pressure and 9,800 PSI burst. Larger than stock for serious flow headroom, fully compatible with both pump gas and E85, and ready for whatever tuning and injector sizing you've got planned — or already dialed in. The restrictive banjo bolts are gone, replaced with a straight-through adapter design so fuel moves freely from tank to rail. Every fitting is crimp-style — no cheap screw-on ends that weep and leak under pressure. Just clean, reliable fueling that'll outlast the rest of your build. Every line is hand-built to order right here in the USA. Custom lengths available — just reach out before you order. Fitment: Toyota MR2 SW20 with Gen4 3SGTE swap (Caldina GT-Four sourced)
