Hmmm, I’ll screw around with it a bit. All parts I ordered are delayed cause of these damn winter storms. I’ve been to 3 hobby stores and no one carry’s parts for 1/5 scale OR helis anymore.... I still need a receiver for my trex700 :/

Is there a spot for a Allen to back out the thread. Looks like one is from a old batch possible. Don’t look like they inspect stuff before they package and ship

Ok so update. Everything back together. Went for first rip today, started GREAT then after a couple minutes it died. After continuously trying to start it when I was pressing the primer on the carb the gas was flowing backwards and the “inlet” side was feeding back into the tank when pressed. I went to simply switch the gas lines and the fiddlesticking peacock on the carb snapped. Need help please lol. Spent a ton of money and it broke within 5 mins 
These are a couple pics... isn’t the fuel feed supposed to be on the top??

One of the best suggestions I have to start with brother is get some fuel quick disconnects at ddm or Detroit performance and this won't ever happen again
As for the gas inlet, if it's removable replace it with a brass fitting

Make sure your isolator and carb are nice and tight as well?

The top parts are sold at DDM. I don't like quick disconnects, just another point of failure. Fuel line is cheap. Learn to slit it and shorten it. In truth you don't go through a lot of it. Live and learn.

I have them installed and love them, I've pulled my tank out of my Vekta atleast 10x now, yanking hoses gets old, its not so bad when the carbs have brass fittings, but the only fail point I see is o-rings, their a simple replacement

Cant say I have issue getting my fuel hose off, but I also started using stihl fuel line, which is much more supple then tygon. Doubt I'll ever use tygon on an rc again.

Welp I was literally about to swap them over ?? I had vids and pics ready for everyone. All the upgrades and engine work I did all myself, full bottom and top end upgrade/ rebuild
Can anyone point me in the direction of brass fitting that will replace this plastic poop?? I don’t want to have to buy a whole new carb. I legit just put $600 into this rebuild and I got 5 mins of run time lol. My bad for having the fuel lines mixed up but wtf is with them snapping??? I’ve been into gassers and nitros my entire life and have never had one of these snap. BTW this is the aftermarket fuel line I bought from DDM which is thicker than the stock, I figured it should have been fine though

Theres no brass fitting for them, the white piece gets replaced as a whole unit.

And the thick DDM line sucks, hence why I don't use it anymore.

Patience and slow twisting to remove the fuel lines. Remember its not a race to remove fuel line because clearly in the long run you end up right where your at

WELL, i red necked the F out of the fuel lines to try and run it before the new parts come in and i cant get it started now.... the rubber grommet for the gas tank isn't all the way in and theres no seal because i broke the rubber using a flat head to get it all the way in. Is this why it wont start? because it needs to be pressurized? I have the main fuel line switched to the bottom inlet because i originally thought the bottom was the return, but it wont start at all now.
