The splash guard will keep water that drains down off of your electrical connections. But with the cap off, you then leave the wires exposed to any, and all water that gets sprayed up by your front tires. Trust me on this one. I left the fuel pump access panel off one time, and had to drive thru a thunder storm on the way home. My trunk was a mess, with grimey water sprayed EVERYWHERE inside the trunk. If you want the extra protection, I'd leave the cap on, but cut the edges off. Then simply glue it to the boot using RTV sealant. That way, you'll keep water from entering the tank, incase the boot is breached. And the wires & fuel pump don't corrode from water standing in the boot. A weak spot in the electrical circuit for the fuel pump is where the wiring harness pluggs into the Inertia Switch, to ground the pump. Too much resistance on the line, and the wires will overheat, and melt the plug. Yet another "Ask me how I found out about this the hard way!" problem I discovered... -Robert vin 6585 "X" --- In dmcnews@xxxxxxxxxxxxxxx, "content22207" <brobertson@xxxx> wrote: > In lieu of an upper cover I have a splash guard attached to the outer > face of the spare tire well (deflects water from the windshield > plenum).
