Prep Work For Sears Pointless 2019 (Continued)

Last weekend I work all weekend on the new fuel system.  As I took it apart , it became clear why we had several failures.  This included:
  • The transfer line on top of the tank was empty (no a go sign)
  • The right Fuel tank was full of fuel which the gas tank meter showed.
  • The left lobe was empty, so no fuel transferring was happening
  • The Fuel pressure was just below 40 psi.  We need to be near 50 psi.
  • The fuel pump connect on the top of the pump was almost off.
So, after all that, it might be good that we are going in the surge tank direction.  Last night Sparky came by and added his parts.  Things like the Z's Data system was upgraded, the D's fire suppression system electrical wiring, and the new fuel pump system.

Thanks Sparky!

The final evenings activity was the test of this system.  We had mixed results.  The lift pumps work and fill the surge tank. So that is good.  However, the high pressure pump is not getting to pressure into the rail.  After some trouble shooting (confirming things like the pump in the correct direct, surge tank has fuel, fuel regulator set, and a quick running of the engine) I think the trouble is the pre-fuel filter.  This filter may not flow as advertised.  My next set is to exchange it for one that is known to flow at the elevated rate.

8 days left.  Plenty of time.....?
