Actually, the factory sending unit wasn't accurate. It reads too high. This is why the pressure gauge stays up near the upper end most of the time. Marty Maier has researched this extensively and used a mechanical gauge to verify this. He located a sending unit with the correct characteristics to produce *accurate* measurements that agree with the mechanical gauge. He is offering the replacement sender at the Mid-State DeLorean Club web site at http://www.midstatedmc.com/ under Parts. Mark Noeltner VIN 6820 At 06:40 AM 8/6/00 -0400, Walter wrote: >.
