NEW FUEL SENDER INSTALL WITH FAKE (THEN REAL) WALBRO 255 - LS1 VL CALAIS PROJECT

In this episode I modify and install a new VL to VN EFI fuel tank sender (from Rare Spares) and a Walbro 255 in tank pump. Unfortunately I find out the hard way the pump is actually a cheap copy. Then I do some pump performance testing, before installing a real Walbro 255.

Real Walbro pumps should be from TI Automotive. My fake pump weighed 290grams, and the real pump weighed 358grams and contained preservation oil.
