For fuel door release issues, see link: http://rivperformance.editboard.com/t3111-faq-fuel-door-release-problems

For general rust concerns, see: http://rivperformance.editboard.com/t6233-faq-rust-areas-concerns

So I was pulled into the gas station today. I hit the fuel door release button. I heard the click I get out and the door isn't open. I hit the button a couple more times then I decided to kinda pry with my fingers. To my surprise the door fell right off the car and was hanging by the strap that connects the cap to the door. I see that the hinge broke and its a simple repair if I can get the part. So that leads me to my question. Anybody know the best place to find this part? I'm thinking junkyard would be best but probably low on rivieras. Painting it is not a problem. Thanks for the info.

Just google Morads auto parts.
They will ship you one, great prices, excellent service.

I got a door/hinge/spring from the dealership about two years ago. It was surprisingly cheap.

Thanks for the info guys. I was actually able to fix it today. The pin in the hinge is what broke. I punched it out and replaced it with a new pin. Were back in business now. Again I appreciate the info.

PostSubject: Fuel door hinge pin... this bites.    Mon Jun 04, 2012 6:02 pm

Lost my fuel door when the hinge pin broke at both the top and bottom ends. Appears to have rusted right thru. Does not look to be easily, or even at all, repairable. I'm not surprised, after having to replace the filler pipe assy 2 years ago due to bad rust issues.

The problem will be access, not a pin, at first glance.

Dave, just remove those two 8mm bolts that hold the hinge in place and make a pin.

Yeah, I'm not saying that replacing the pin will be difficult, it just appears it will be a pain to work my hands inside for installation.

Haven't tried anything yet, I've got bigger fish to fry these days. [ 350 to 455 swap smile ]

I kinda wonder if a replacement pin could be made of a piece of stainless wire. Those hinge pins are hard little wires,

I wonder what one of the gearheads at my local GM dealer would say.

The fuel door shows with the hinge on the monsterpartsonline.com site but shows as "discontinued." You might want to check with a dealer for "vintage parts" they may in fact be able to get it for you. About $30 - $40.

That pin oughta come out with an arbor press and a drift, after you knock off the rust a little, Then you can press a replacement in.

Upon closer examination, I don't think this will be all that hard to deal with. I should be able to source a stainless pin of sorts here at work also. Just needs to be a tight enough fit in the hinge...

IIRC the base of that hinge actually is held on the car with screws. Look close.

Ok, door is off. I've soaked the hinge pin with PB blaster for a few hours. This sucker is really rusted in. I do not believe it will drive out, from either the door or the bracket. Time to search for a replacement.

Can't drive it out, have to press it out or drill it out.

I am thinking car-=part.com would have one available -- anyone with a Riv on the lot would be fair game even if they don't list the filler door.

For the rest of you - if yours is not rusted yet spray it with lithium garage door lube or some such.

Dave,
Go on V8 and PM George Nenadovich (GStage1). He has gotten me Riv parts. He's in the yards all the time. Give him a shout, he can help.

Found one from an ebay seller pending pics. Already posted on V8. Will check local yards when i get a chance. Drilling it out... didn't work well. Can't press it out here.

Ok, who can tell me if the 95-97 and the 98/99 door will interchange? They have 2 different part numbers. My first guess might be how they are mounted? I may be able to get a white 96 door, but need to know if it can be used on my 98. Anyone???

Dave,
Just heard from George. He said he has one for you, and is getting another today. George is the best!

Yep, he's hoping for a dry day today to go see the white car. I am still concerned about the differences in the model years. It appears the early ones have a bracket built into the back side of the door, to hang the gas cap on. Mine simply has a notch on the side to hang the strap onto. I likely will need to remove that early model bracket for my use. After I replaced my filler pipe a couple years ago, the gas cap now sits right up almost against the back of the door, leaving little to no space for that gas cap bracket. I'll just have to figure out the best way to cut it out.

Got a nice white 96 door from George, and with some mods it works fine. Not diamond white, but white is next best thing...

Had to cut off, then grind down, the brackets on the backside. They interfered with closing the door as the new fill pipe and cap are higher up and out than the oem. Also had to cut out a section of metal in the lower section of the backside for clearance. But hey for $20, it looks a heck of a lot better than no fuel door.

I had the same thing happen to me last week. My car is almost 15 years old, and had 248k miles when the hinge pin failed. Based on typical MPG, and average miles between fill-ups, the car has been fueled an estimated 650-800 times in its life. I was about to pump gas and the fuel door wouldn't open, so had to pry it up with a soft piece of plastic, then it popped. The pin had rusted through at two points:



On the mounting bracket there are two tabs, one at each end. Bend these out straight. I used a bench vise to hold the bracket. Don't worry much about the paint - it's going to chip away:



Clamping the bracket in the vice, support it so the pins can be driven out. I used a piece of scrap steel. Lube with PB Blaster for a few minutes. To drive out the pins, use a drift or whatever you can find (small driver bit works):



Done:



For the fuel door, you'll need to cut out the center portion of the hinge pin. I used a Dremel cut-off wheel:



Drive out the pins:



Done. Now I need to clean and protect the hinge parts from corrosion, then repaint them. I will probably use rust converter in a spray can, then paint with a quick dry enamel. I don't really care about matching the color, so it will be probably be black.

For the hinge pin replacement, I picked up a 1/8" brass rod (3" long), from which I will use just a couple inches. If anyone else is performing this repair, let me know and I'll send you a piece.
