I can set you guys up with everything you need for about $200. Check your fuel pickup to make sure there are no wires coming off of it. If not you will have to replace the pickup which would be included in the $200 price.
Also look at the oil tank and see if there is a sensor on it....we can make that work too if its there.
It would have OEM seals for the ebox and everything.
So you would have to replace the pickup, drill out one of the wire holes in the ebox, insert the wires and connect them. Then, run the wiring up into the hood and put the gauge in.
