Chrysler Repair: SLOW fuel fill 1996 Sebring Convertible, vent tube, horizontal pipe

Question
Read your post of 5-15-08 on the same issue with the LHS and have seen other posts on other sites, but I think there has to be more to it if it is a fairly common Chrysler problem.  My wife'e Sebring has had this problem for a while and finally yesterday I went under the car to see what I could see.  The filler neck goes horizontal just before the tank and there does not appear to be any direct venting back out the filler.  The vent tube off the top of the tank goes to a steel tube that runs to the front of the car.  I did not trace it, but is there a valve somewhere that quit working and does not vent these cars properly when filling?  I read one post where the guy drives his ford pickup onto a block of wood when filling up to help the gas flow through the horizontal pipe.  That can't be a real solution.

Answer
Hi John,
You are correct about there being no vent on the filler pipe part of the system. As far as I can tell the steel pipe that goes to the evap cannister on the front right side of the vehicle, behind the facia. I believe that the rollover valve mounted on the top of the fuel tank which is attached to the pipe is the only valve that might be wrongly closed so as to pressurize the tank during the filling process. There seems to be no other explanation that I can see about why this slow filling occurs. Maybe others will see this q and a and offer a better suspect. For now, I would look at the rollover valve.
