    Known to be trouble. Often loses prime. Very picky about sensor on filter system. I use a general purpose electric fuel pump to keep my pump primed. I have also run a switched hot wire to turn on/open pump inlet valve to let electric pump circulate fuel. This helps prevent air locked injectors that will need bleeding-use wrench to loosen lines at injectors. Tighten lines back up when fuel starts squirting out as engine turns over and starts "hitting" again.
