heirfaus Posted August 27, 2009 Report Share Posted August 27, 2009 I am wondering if anyone in the Portland area has access to a smoke machine. I want to get rid of the fuel smell in my car and I cannot find any liquid fuel leaks. If someone has a smoker I can hook it up to a vapor line in my trunk and find the leak. let me know. Thanks, Chris Quote Link to comment
datzenmike Posted August 27, 2009 Report Share Posted August 27, 2009 Is the PCV valve system working? Is the fuel vent line properly connected to the intake/PCV? Is the valve cover vent hose connected to the air filter or just have a small k&n filter on it? Quote Link to comment

I have since changed and it is not hooked up to anything....I don't remember where it was hooked up to. This is what I have right now.... Should I just tee into a line and hook it up to the where in the engine compartment? Quote Link to comment
datzenmike Posted August 28, 2009 Report Share Posted August 28, 2009 The vent line is usually an aluminum tube which goes to a T beside the manifolds and intake vacuum draws the fumes in. Quote Link to comment

ggzilla Posted August 28, 2009 Report Share Posted August 28, 2009 Later 510 tanks are non-vented, so don't simply T them into the filler. The vent line runs up to the engine compartement to a flow-valve and to the air cleaner or better yet fit a carbon cannister from and 80s or 90s Datsun up front. Well you could T it to the filler if you fit a vented cap. Make sure it is not a Datsun cap, those are either flat caps or pressure relief, but not vented. Quote Link to comment

I thought the canister above the fuel tank was a charcoal canister. No? I like the idea of adding a charcoal canister. The only thing i don't get is if I hook a line up to the intake manifold that would create negative pressure in the tank...... take the vent line in the first pic and run it to that elbow in the second pic. thats how we had to do steves car. I don't understand what this accomplishes. Also, which end of the hose from the first pick? you mean phils car right? on my 4 door i ran my own lines and only left the line that is by the master cylinder. i must report no fuel smell. What do you mean ran your own lines? You ran your own vent lines? why? and the line by the master cylinder is being used or not? Edited August 28, 2009 by heirfaus Quote Link to comment
