Indigo FWC

[joe_db]

260 hours later with the Indigo FWC system.
+Engine runs great.
+Engine totally reliable. No running issues.

-Still cannot find where very slow leak of antifreeze is coming from. not sure it has anything to do with Indigo.
-Not related to Indigo, related to Moyer: The Moyer thermostat kept the temp
too high for me (200-210).
No thermostat- 140 tops, too cool for me.
Original thermostat: 150 to 170. I like that temp range.

Very happy with the Indigo FWC with the no longer available brushless DC pump

Did Indigo quit selling the new style pump and go back to the old Johnson pumps? I notice all mention of the new pumps is off their website.

I have given some thought to putting the FWC system back on, I have plumbed in a fuel/vapor return line to the fuel system so I no longer have issues with vapor lock.

Yeah Tom of Indigo said he got a batch of the new style pumps that wouldn't hold up and went back to the old style.
The first ones he got are reliable. I am glad I got one of those. Runs like a champ. Wish I bought a spare.

Dang. I really want to put the FWC back on since I got the vapor-return working. I have two of his original pumps that work fine, but are IMHO not quite powerful enough.
I might go to a mechanical pump or maybe try these:

Tom ran into the Chinese Problem, you may get really good stuff cheap and at any random time it can be terrible. You might order 5 pumps and get 3 good ones, one marginal pump, and one DOA.
