gas cap?

[thgstang]

Is it normal to open the gas cap and hear a vacuum sound, like air going in?

Sounds Like the vent hole in the cap is blocked.

yep, make sure the gas cap is venting well or you might fing youself stall in the middle of a race

that is one thing on the to do list you need to vent the gas cap you need to find a fitting for a fuel line. we use the ones that go into the exhust of the nitro cars it is threaded on one end and a hose barb on the other end drill the hole smaller than the thread of the fitting and thread it into the hole in your gas cap then get some fuel line tubing and a inline fuel filter and install it some thing like the pic below.

Nice I will do that on my for sure. And inside the cap stays the same or do I have to modify too?

you can also run it to the air filter like i did mine, racetruck should have pics of it but i'm not sure
