To start, this is strictly a trail rig.
I relocated the fuel tank inside the rear hatch for clearance (I've destroyed two tanks in my 91.) I was hoping to use my old fuel cell. But alas, this system has the regulator built into the pump and has no return line from the fuel rail. I ran it several time through the summer without issue. However, Labor Day weekend was a different story. More than once, it would just die while idling. Especially if things were a little hot from really working the engine. Crank and crank, no-go. Wait 20-30 minutes and it'll fire right up. From what I've read, the regulator/check valve can be an issue in the OEM fuel system. But, is it the fuel? I tried bleeding the fuel rail at the pressure port and got some air (thinking it was vapor locked.) But, it refused to fire. No, I didn't check for spark...as I was slightly irritated. Thoughts on this?
Back to the fuel cell. I'm seriously considering revamping the fuel system. Use the fuel cell with an external pump (which will provide over 49 psi) and a bypass regulator. Anybody ever done something like this? Should I put the regulator at the tank? If I do, that doesn't help the heat soak that tends to plague this generation of injection. Or, should I remove the Schrader valve on the fuel rail (pressure gauge port) and utilize that port for a bypass regulator with a return line to the tank?
I'm open to ideas, so bring it on!
