I have triple Mikunis and the sending unit seems to have failed after doing a leak down test and putting in a new regulator. Should I weld in a fuel cell ? or spend the $254! for a sending unit and keep it "stock"? The decision is killing me. Destroy the stock trunk or go with a replacement sending unit? Take a look at the car in the rides section tim280zx white, 1981 280zx that has been converted from the FI then tell me what you think. Thanks!
