Wedgewood64 Posted September 2, 2018 Share Posted September 2, 2018 Hello all, After determining that the no doubt original rubber hoses from the tank were leaking, I just dropped the tank, according to the procedures found on the Forum. Happily, straightforward operation, tho I still smell like gas. After doing this, I kind of realized that I didn't really need to take the tank out -- I could have just let the front end of it down, I think, and changed the hoses. Well, anyway. So it's out. Now, aside from taking on the Riviera Rattle problem (helpfully diagnosed on: http://forums.aaca.org/topic/211803-riviera-rattle-first-generation-cause-and-repair/?tab=comments#comment-1087545), should I do anything else now that it's out? my fuel gauge shows 1/4 when empty, and buries the needle when full: but do I really want to mess with that? Should I leave the nice yellow sender wire as is? And does all this moving around risk dislodging crap that will foul the filter? Any precautions on that front? Should I empty the bit of gas in there out? Many thanks in advance, Nick (ROA number ten thousand something) Link to comment Share on other sites More sharing options...

For sure pull the sending unit, check the filter sock and clean out the tank. Here's a picture of what my filter sock looked like. Might be a good idea to redo the ground wire as well.

RivNut Posted September 2, 2018 Share Posted September 2, 2018 While you have the tank out, add a dedicated ground wire to the sending unit. Otherwise, it's only grounded via the lines and where they're connected to the body. 1 Link to comment Share on other sites More sharing options...
jframe Posted September 3, 2018 Share Posted September 3, 2018 All good advice. May just need to bend the sending unit arm slightly to cure the gauge reading. My new sender suffered from the same sort of issue, except it read 3/4 when full. Link to comment Share on other sites More sharing options...
Wedgewood64 Posted September 3, 2018 Author Share Posted September 3, 2018 Thanks Bill, Ed, Jframe. I guess I'll venture into the tank, then. Thanks Bill for reposting that picture of the ground wire set-up--I had seen it somewhere in the forum but then lost it. Those rubber insulators you added--not stock, right? What's the purpose? (Definitely need a ground with those, I guess). nick Link to comment Share on other sites More sharing options...

Part of my rattle problem was things hitting/rubbing on the trunk floor. Scroll down from the beginning of the link you first posted. (I copied it here) You will find where I posted pictures that showed this and talked about the fixing of my rattle. Bill Link to comment Share on other sites More sharing options...
Wedgewood64 Posted September 3, 2018 Author Share Posted September 3, 2018 oh, duh, right. Brain upside-down. For some reason I thought those ran in the channels for the holding straps... Link to comment Share on other sites More sharing options...
Wedgewood64 Posted September 8, 2018 Author Share Posted September 8, 2018 pulled the sending unit: my strainer sock wasn't as beat as Bill's, but getting a new one from summit. Interesting objects rolling around in tank, turned out: a spring, a rivet... Further question: the sending unit had a non-sealed cork gasket. Nice shape, totally reusable. But: to seal or not to seal? I noticed from stains on top of tank that it would appear gas got out. thanks, nick Link to comment Share on other sites More sharing options...
Wedgewood64 Posted September 23, 2018 Author Share Posted September 23, 2018 Success! Whole thing was easier than expected. I ended up simply cutting a new gasket and sealing it. Added the ground wire. And I bent the float arm up about 5/8 inch, which was a total guess but I ended up nailing it: when full, the needle now reads F and when empty, it reads E. I was surprised that the tank itself was so clean inside. I guess I was expecting 55 years of crud, but no. The 5/16 strainer sock I ordered from Summit was too small--maybe there's a OD vs. ID problem. But I just drilled it out a bit and stuck it on. Fit well. Worse part of the whole operation is definitely emptying the tank; but bleeding it out by jacking up the back and unhooking the hose behind the front wheel was easy enough. Did get a lot of gas down my sleeve... 1 Link to comment Share on other sites More sharing options...

jframe Posted September 24, 2018 Share Posted September 24, 2018 Bending that arm was the single biggest cure to my gauge reading problem. Glad you got it fixed!! Link to comment Share on other sites More sharing options...
