Speaking of CB, fuses, fusable links, contactors, Mr. Nuckolls’ figure Z-17 has no master contactor, just a switch, which is rated for 20 amps. My understanding is that a simple switch is deemed...

IMHO, DanH’s posts in the thread he referenced above bring common sense in the witch craft of hot starts we are trying to practice. I just want to make sure that reference doesn’t get overlooked.

True, but I think they deem the 125 micron filter to be adequate to protect their boost pump, not necessarily sufficient for the entire system. The fuel injection system makers seem to want to see...

Very interesting product. I am planning my fuel system and thought of getting by with just an inline filter upstream of the boost pump. This gascolator looks to be an intersting alternative. I have...

Boost pump -- in series or parallel to engine-driven pump?

On a conventional FI engine, are there any benefits to plumbing the boost pump in parallel to the engine driven pump? The way I see it, putting it in parallel, makes the system more complex because...
