We
have had a few calls concerning priming the FASS Systems, not the
HPFP's, during the installation process. We have discovered some of
the Viton by-pass balls are not perfectly round creating a priming
issue. However, once the ball is subjected to the fuel, the seal is
complete.
We have added this simple procedure to address all concerns, starting
with serial number 15207 for the FASS 150 Series and serial number
2360 for the FASS 95 Series. For uninstalled units before these
serial numbers we have come up with a simple solution.
Before the installation, review the following process:
Remove
the pump assembly, the upside down T block. Notice the 5/8 ball; apply
some grease to the ball seat and place ball back into place. Reinstall
pump assembly making sure the 2 o-rings are still in place; torque
the 4 bolts to 110inch lbs using a criss- cross fashion. Note the
o-rings are located on the pump assembly of the FASS 95 Series, it
may be necessary to apply grease to keep the o-rings in place during
assembly.
We
are researching a more perfectly round Viton by-pass ball, I am
truly sorry for any inconvenience.
