s.dartmouth ma,
So i had a little problem with my engine flooding and i was building pressure in my gas tank and didn't know what was going on. So with alittle help of hbf i was able to track it to my gas cap vent. It wasn't clogged with dirt and everything look good but it wouldn't vent, so i decided to do the gas cap mod. I am not the first to do it, i just used someones else idea to do it to mine. The hardest part was finding the fittings to do it.

So i started by drilling the old vent hole to accept the m5 threaed fitting,and put a oring under the nut to help keep dirt out ..



Then i dremeled the gasket alittle, i should have pluged the vent and drilled in the middle of the cap and i wouldn't have had to do this part...







This is the fitting i used...



This is were i ordered the fitting from, http://www.hobbyking.com/hobbyking/store/__13244__90_Degree_Brass_Fuel_Pipe_5pcs_bag_.html

Another good mod man, do you have a fuel filter or something on the other end so you don't suck dirt?

Rite now i have just a air stone from my extra fish tank stuff. Seems to be working good as of now. I know if it flips upside down it will leak gas out that's why you surpose to have a check valve on it. I just haven't found one yet......

I do that to mine as well. I use a small pressure nipple made for nitro Rc exhaust pipes and use small nitro line clear out the back of my Baja.
