Fuel tank valve???
 
OK, so today I dropped the tank to fix what ever is leaking and preventing me from passing smog. When I dropped the tank I noticed a small diameter vent line that was coming from the rear passenger side of the tub that was unhooked. I traced it back to find what I assume is some kind of rollover valve. Well, the valve was split. I have looked high and low for this damn thing on the intrawebs and can't find anything.

Here it is:

Does anyone know the correct name for this thing and where I can get one?

just looks like a vent valve, not real sure though.

Thanks for posting up so quick Dave! :wavey:

Yeah, that's kinda what I thought. I can tell you that if you hold it as it were mounted and put vacuum or pressure on the port there is no restriction.

If you roll it over and hold it upside down you can neither put vacuum or pressure on it. I'm thinking of just bypassing it.

The only real problem I see is if I put the jeep on it's top, gas would be able to run to the evap canister.

What do you think?

i would say do it. was the hose off it cracked, causing a problem with smog? or how was it causing a prob?

the way you describe its function, rollover seems like the only way it functions.

Yeah, the small line was attached to the top, but the two lines coming out of the tank for the evap on the passenger side went into a tee and then on to this. This is a larger assembly that incorporates a molded in hose at the bottom of the grommet type lower half. The hose was broken at the assembly. I'm gonna have to say that this is the reason I didn't pass smog. Everything else was hooked up and appeared to be functioning.

I am glad I dropped the tank though. As you can guess, 21 years of being sandwiched between the tank and the tub weren't very kind to the hoses. Every hose on the tank shows signs of weather checking and dry rot.

Sweet Zombie Jesus! Last night, I went to the parts store to get replacement fuel hoses and vent hoses. I bought 6' of 5/16" Fuel injection hose to come off the pump, 4' of 3/8" regular fuel line for the vent side, 8' of vacuum line to connect to the metal line feeding back to the evap canister, a small assortment of clamps and one tee to replace the rollover valve. 70 freakin' bucks! They sure are proud of that fuel injection hose! :rolleyes:

Anyway, we have an appointment this morning at 9:30, so I went out to the garage early and cleaned up the tank and put a nice protective coat of paint on it. If all goes well, I'll have this thing back in this evening.

I'm a little embarrassed by this, but I had to read the instructions for replacing the fuel pump. In all my years messing with cars, I've never had to replace an in-tank pump.

So, it's either gonna work or turn into a big green bomb! :D

Pulled the old pump out. It's a blessing that I pulled the pump. The hose that runs from the pump to the top of the sending unit was a mess. The casing had almost slothed off of it and it came off the old pump in a gooey mess.

I started putting everything back together. Had to run a new ground on the pump assembly. Then, I realized the so called "fuel pump kit" I got didn't come with a strainer. After calling around, I finally found one at *GULP* AutoZone... Of course, I looked it up myself on-line. I really don't trust the know how of the guys behind the counter there. I guess I worked parts for way too many years to not look up my own stuff.

Anyway, another $11.00 to the tally. Holy catshit, this is turning into an expensive fix. $109 for the pump, $10 for a new cap, $5 for a new fuel filter. $35 for new gas tank filler hoses, $70 for the fuel line and vent hoses, $11 for the strainer... All I can say is it better damn site pass this time! :banghead:
