Fuel leak

[magnum57]

My MT has a new fuel tank inline filter and upgraded in tank filter. All new fuel lines. Original fuel cap. When I give it throttle fuel comes out of the rubber fuel line holder where the two lines go into the tank. Leaks around where the rubber fits into the plastic tank. I tried it without a fuel cap and still leaked. Like my MCD I thought I might need a breather tube off the fuel cap. I hate to use a glue gun to try and seal the rubber into the plastic tank.


It doesn’t seem like the tank is creating a vacuum. When I take off the fuel cap there is no pressure build up. Like my FG when I take off the cap its under a lot of pressure and you can hear the relief of air pressure. Any ideas

Cover the rubber grommet with Shoe Goo. Worked well for me and it is removable.

I replaced my fuel line with this. http://www.davesmotors.com/store/product623.html


It has a larger outside diameter and makes the rubber gromet tighter. I haven't noticed any leaks so far.

Redcat has a new fuel bung coming out. That should fix this particular problem.

Yes it sound like a lose fitting. The hose is not tite in the rubber. Beiger outer diameter hose should fix it.

I’ll try the fuel line that KUN114 suggested until Red Cat comes out with the new bung. Thanks Guys.

SPRINT77, You are the MAN. I took your advise and got a #24 Viton O-Ring slid it over the fuel lines and tucked up under the top side of the bung. Works great. Tank doesn’t leak any more. I hated the thought of using some sealant. That would look like crap.


Thanks Bro

Glad I could help, now just get you an extra o-ring for the pit box and you are in like Flint.

I don't know Flint is in pretty good. At least the Flint I am thinking of.

Hey Bro,


Got my fuel lines today. HUGE diff. With the Viton O ring and the new fuel line. No way this baby will leak. I used 1/4" fuel line but I see it was soft. The DDM line is very firm and expands the bung perfect.


Thanks Guys

You need to remember that Sprint77 chimed in with the tip on the O ring, he is REAL sensitive when he is not recognized for his input

Of course. SPRINT77 is the MAN. Awesome tips


Thanks

The new fuel bung in the upgrade kit should fix this as well.
