CA FS: Harnessworx / Jabin Wood Dual Tank Upgrade Relay Harness/ Switch/ Valve - The 1947 - Present Chevrolet & GMC Truck Message Board Network

z71se · 07-15-2020, 05:33 PM

Brand new Harnessworx dual tank harness and relay setup. This replaces and upgrades all the wiring related to the dual tanks and will support upgraded fuel pumps that draw more amperage than the EP381 pump. Specifically designed for LS Swaps. Includes chassis harness, relays, selector valve, tank switch, wiring clips. I ended up having my fuel pump wiring tied into my main fuse box so this harness is no longer needed. New these are $375 + shipping and takes 6-8 weeks to make these when he has time. My price: $275 shipped. Save $100+ and have it in your hands within 2 days.

thank you! Have you used this system yourself? I'm swapping a 5.3 into my 75 C20 and I'd really love to keep my dual tank setup...
