Gas tank venting

[claude bigelow]

While I was running the new engine it started off great. After about 20min the motor bogged out. I tried everything to get it back started. Then I took off the gas cap and put it back on and it started with no problem. Do I need to make the hole in cap bigger? After a while had the same problem again. So I took cap a loose, put it back and it ran good again. So my question is do I need that snappy RC system? Or is there another way to correct problem?

Sure it works. I like to use the three hole gromet and just run a piece of fuel line for the vent and use a filter on the end. This way it vents both ways.

I just run the vent line up the cage a bit then back down below the tank so if you roll, fuel doesn't leak out.

Just got this today, ill watch the video a couple of times and tackle this next week.

Yup that will work. I cut the fittings for the pick up line and return. And don't use a fitting for the vent line.

Personal preference.

Ok thanks more questions to follow once I get ready to start.

Thanks

Is there a good video out there? The one I just watched doesn't show exactly how to install brass fittings.

The return and vent line you don't want sitting in fuel when tank is full. Pick up line leave long enough you can slide a piece of fuel line on it from the inside to run to the bottom of tank with filter on the end.

So do I use the stock filter, or was I suppose to order a nee one?

you can use the stock filter on the end of the line that you connect to the brass fitting inside the tank. The brass is to long so just need to shorten it and put a piece of fuel line on it to go to bottom of tank with filter on the end

Thanks man, I guess it will all make more since to me when I actually get started. I'll keep you posted.

I bought the whole setup at ddm, under snappy RC.

On my old cars I did something similar. But with my new cars I just don't over tight my gas cap. I just turn to close it but not too tight so that the vent cap gets to work. I read somewhere that over tightning the cap will not help the vent hole on the cap to work properly. Anyways, its been working for me so far.

I do the same thing, really does work. I still haven't installed the kit yet.

Can someone post a pic on how long those brass fittings should be? It's supposed to rain for the next few days, so it's the perfect time to tackle this project.

I ordered the snappy vent system from daves

Tried it, fortunately the chassis caught the cap both times it came off! Then I just drilled a 3/32" hole in the rubber plug, to come back with some brass tubing later. So far I've run with just the hole just fine with no major leakage issues but it hasn't been flipped either.

The snappy vent kit is far superior for a vent system! The ability to route the vent line down and away from the chassis keeps it nice and clean in a roll over with no mess running down the side of the tank like what the cap hole will do.
