OK so my DA50 started acting up several days back (Hard to restart and ran I guess leaner) and I knew exactly what the problem was. I had mentioned in an earlier post that the "pulse line had melted through because it was touching one of the cylinder cooling fins. That was from the factory so check yours and shorten if it touches the fins. That was easy to SEE.

This time when it started acting up the first replaced line was intact but I had put the new piece of line on without any zip ties behind the nipples. There wasn't one from the factory before so I figured good to go. Well I found it this time to be very loose and it was leaking air I'm sure.

I had not mentioned this before because at that point I had not realized a problem. So while in there fixing the pulse line I decided to install my super duper handy dandy Quickfire filter balancer and really get things bad ass. That required moving about 10'' of fuel line into the engine compartment plus a rather large fuel filter that holds a quantity of fuel that gets heated up nicely I'm sure

Took it out two different days after that. First start-up on both days only took 5 flips and she ran great. Landed and refueled and could not get her restarted both days went home. Arghhhhhhhh It used to run great. What the heck changed!!! Well I sez to my self "self all that extra horse **** and fuel line that is now occuring in the engine compartment is what changed" SHE WAS VAPOR LOCKING

I pulled all that crap out put all the fuel line and simple Hanger 9 filter (only 2''of the line from the tank is going through the fire wall to the carb) inside the cockpit like it was before. Hot damn fires and runs like she did before....perfect. No more vapor lock and fires on 5th flip run after run. I'm a so hapeh lifes not crapeh!!! YAY

It doesn't matter if you have a DA, BLT, DLE, ADHD, OU812,

Get the damn fuel lines (all of it!) out from under the cowl, keep it in the cockpit and fly..............
