SLOVAK69 Posted March 1, 2006 Share Posted March 1, 2006 Last weekend I put in new sparkplugs and tightened the throttle cables on my paythfinder, and ever since, I get a very strong raw gas smell when I start it up. after I drive away, I cant smell raw gas anymore. It not me producing the gas...petroleum gas. could I have the throttle cables to tight? What is the recomended tension on those cable? Try and see? much more power with the new plugs, but the old ones were dead. thanks Link to comment Share on other sites More sharing options...
Simon Posted March 1, 2006 Share Posted March 1, 2006 I'd say let off the tension on the throttle cables and see if the gas smell goes away...... The other option is a tiny little fuel hose that runs under the intake manifold......Check the clamps on either end of it.....could be a little loose.

delavoie Posted March 1, 2006 Share Posted March 1, 2006 The other option is a tiny little fuel hose that runs under the intake manifold......Check the clamps on either end of it.....could be a little loose. That's the problem i had with mine.. that little fuel tube, in the cold the clamps would get loose, and piss out alittle gas, after 5-10min of driving it would go away.

88pathoffroad Posted March 2, 2006 Share Posted March 2, 2006 Check all your fuel line connections, one is leaking. Throttle cables won't give you a gas smell with the engine running...it's sucking air in after all, not letting it out. Unless you count the exhaust, but I doubt you'd smell raw gas from the tailpipe without it running really badly. Link to comment Share on other sites More sharing options...
jj big shoe Posted March 2, 2006 Share Posted March 2, 2006 Plus you'd notice a really high idle if you're throttle cable was too tight. Like 88 said, you probably just knocked some fuel related connection loose when you were in there changing the plugs. Link to comment Share on other sites More sharing options...

SLOVAK69 Posted March 2, 2006 Author Share Posted March 2, 2006 It happens just like you said delavoie. After a couple of minutes, it stops doing. it. so you said you just tightened the clamp, and the problem went away? Is the clamp after the soft fuel line from the filter to the manifold? or are the other clamps buried way deep under the intake manifold? Link to comment Share on other sites More sharing options...
Mookie Posted March 2, 2006 Share Posted March 2, 2006 Iirc, you will be able to see two small hose clamps (one on each end of the rubber hose) No hidden clamps to worry about. Link to comment Share on other sites More sharing options...
k9sar Posted March 2, 2006 Share Posted March 2, 2006 I went to tighten mine and one of them was rotated so I couldn't get the screwdriver on the head of the screw. Had to force it to rotate before I could tighten it. Link to comment Share on other sites More sharing options...

thejones Posted December 18, 2007 Share Posted December 18, 2007 Hey, I am new here, actually stumbled on this forum looking for this exact problem for my 92. i smell fuel in the cold weather now too, but it looks like this hose is actually cracked at the bottom, and not just leaking from the sides due to the tightness of the clamps. is this an easy change for someone who doesnt do much work. I have changed brakes, water pumps and alternators, often with help, so i can do some work, but i am not a mechanic. is it as simple as it looks, take one hose off, put another in its place? if so, what size hose should i buy? thanks for any help, i wish i would have known about this place 5 sooner, would have helped out with so many other things.

MikeV Posted December 18, 2007 Share Posted December 18, 2007 I had to tighten my clamps on my Z every winter or it smelled like a gas refinery. Now it is part of winter maintenance Link to comment Share on other sites More sharing options...

Yep, as easy as it looks. Just a pain to get your hand in there to get the hoses on/off. I'm not sure on the size, but you can (if you have other transportation for a short while) take the hose with you to the parts store, and match up the sizing.

k9sar Posted December 18, 2007 Share Posted December 18, 2007 it's real easy if you take the extra half hour or so and remove the intake manifold. I have big hands so that was my only option. Link to comment Share on other sites More sharing options...

Simon Posted December 18, 2007 Share Posted December 18, 2007 You may get a little bit, but shouldn't get much. If you're worried about it, take the fuel pump fuse out, and start the truck and let it run until it dies.....that will ensure most of the fuel in the lines is burned off.

Xmas Posted December 19, 2007 Share Posted December 19, 2007 mine has a little fuel smell on cold start ups. when the motor is warmed it, all is fine. I can be patient for 5-minutes or so. Link to comment Share on other sites More sharing options...
Smithk Posted December 19, 2007 Share Posted December 19, 2007 Wow, I better check mine out, since I work with gas and other petroluem products all day, I thought it was just me smelling and not comming from the truck.
