Hi Folks! I have a ute that needs additional fuel range and redundancy. The ute is a 1995 Hilux US model with a passenger fuel tank. Build date Jan 1995 83000 original miles. Extended Cab. 4wd. Stock bed is gone. ---The exhaust is rerouted under the cab to a snorkel that goes up behind driver side cab corner for fording. ---This leaves the bed underside available for the second tank. ---Tank must be mounted in between axles. Aft of axle will change weight distribution. ---Canopy is being mounted along with hitch receiver platform. Weight is going to be saved for that. *I require efi fuel pump redundancy. * ---I can mix and match any manufacturer, as long as line pressures are right for the EFI. *Toyota parts preferred.* ---I already have a system selected for tank switchover and gauges. Valves come from the Biodiesel community. They have amazing 3 way viton seal valves with threaded ports that are designed for heavy usage and oils.. NO FSVK-1 fuel valve bullshit. I design circuits for my job. I am designing the control systems for the pump and gauges with LTspice. I am keeping emissions equipment systems. Based on the preceding parameters, I need brainstorming about what fuel tanks fit in that position. Once I have the information I need, I will create a write-up with the build for the community. Thank you!
