I use a 3 line system as opposed to a two line with one as the vent and the feed line having a Tee in it for fuelling is a potential problem point which can introduce air into the system
ok , I get the three line. but why have a second line with clunk, why not apiece of grass ending just inside the tank? it should fill up to the top anyway? or am I missing some thing?
this tank was BAD, one of the lines went into the back of the tank (to long ) and was bending around all over the place. neither of the lines had a felt clunk on them.
This whole installation is poor, he cut big holes in the fire wall instead of stand offs. The carb went into the hole in the fire wall for clearance.
do you pad the fuel tank with foam, like we do with glow?
just more fun for me, I have the engine off now and am putting it on a mount to run it off the plane. I should have done that in the first place.
I have a lot of planes to fly, this is not stopping me from flying. Its just something to play around with and fix.
I know I am asking a lot of question, but this is such a great place for info. I like doing "it right" and don't mind the time to do it.
thanks
