Walt & List Recently Universal Studios in LA sent their BTF car to DeLorean Motor Center to get it running again. One of the things they had done was to have a custom made metal tank installed. Whether it was stainless steel or aluminum, I don't know. Don and crew were installing it the day I was there. In any event, the one idiosynchrasie of the D that really bugs me is the fuel pump hum and anything that could be done to eliminate it would be great.
