I installed 2 90* fittings on my KR with a 2180 and it really messed up the fuel flow. I put a new fuel line with a nice sweeping bend and cured the problem.

I think I am going to get rid of the gascolator and replace it with a fuel drain in the lowest spot along with a fuel filter behind the firewall as I have a header tank. I always drain the gascolator before every flight to check for water and I think a simple fuel drain would serve this same purpose. I think this will at least eliminate vapor lock being caused by the gascolator. >A good first step is to verify you have >at least three times your maximum, engine required, fuel flow in nose high >and nose low attitudes.

After taking a quick look at the fuel supply line for the revflow carb I noticed that fuel is fed into the opposite side of the carb (the side facing the front of the airplane). In order to do this there are two 90 degree fittings used together to bring fuel in from the rubber supply line. This looks like it could be restrictive especially being that it is gravity fed. This weekend I will do a fuel flow check and see if those fittings are restricting the flow. If so then possibly I will extend the rubber supply line and make a 180 degree radius into the carb instead. Any other suggestions or comments?? _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
