Fuel leaking from throttle body
I had to take my TB off yesterday to figure out a sticky throttle problem. Well the fuel inlet and outlet on the back were really hard to get back in with those hard lines. Hopefully I didn't cross thread them. Anyway both are leaking. Is there a trick to putting those back on? I've tightened them pretty hard already. The main bolts that go into the TB r in good shape. The nut sleeve things r a little rusty, but the leak seems to be where the main bolt meets the TB.
Edit: are there supposed to be little gaskets on those bolts that go into the TB?

Supposed to have a plastic washer at the indented portion at the end of the screw point.

You should have plastic washers on those. I got mine in a Tb rebuild kit. Those lines won't seal without them. You may be able to get them seperate but not sure about that.Make sure that the old ones are not still in the Tb. Hope this helps

Re: Fuel leaking from throttle body
I seem to have a similar issue with getting one of those lines back in place right everytime I remove them on my car. I have a TBI pod spacer on mine so I raises mine up just a little. 2 things I always do with mine since I ruined one of the pieces on mine after the first time doing this. There should be a bolt or nut on the drivers side near the valve cover I think, you can loosen this and you should be able to manuever the line a little more. Second thing is I usually get someone to help me by holding the line in place while I try to tighten the fitting in place.
