Please let me know if you run into any problems. Use the OEM tank straps, clean them up with a wire brush or grinder. Buy new tank J Bolts and gas fill neck rubber. Vans Auto is really nice for everything.

Appreciate it! I'm guessing I'll be in touch. I'll also keep a tally of curse words and bloody knuckles throughout the job!

Have the funds for a new gas tank. Mine was trashed!! Any info on where to find one for the 65 monaco?

Gas Tank 1966 Fury 1965 - 1966 C-Body

Ok………some good miscellaneous information on the fuel tank and components. First off, my tank was trashed. The fuel sending unit/pick up ring was so rusted, I have not yet even gotten it off. So, I bought the following.

Ebay- New fuel sending unit/pick up line-filter. Very common $40.00

New Carter Fuel Pump $25.00

J-Bolts. Extremely hard to find the right ones for an old C-Body. I thought they were ALL the same with a 9/16 nut, but I suppose some later cars B-Body and E-Body were different lengths. I found older C-Body J-Bolts from Vans Auto. Part number (J-BOLT). Think they were $9.00 each. Good service, had them in 3 days. They are about 6 threads longer than the OEM, but seem perfect.

The filler neck and seal. My filler neck was pretty bad, and I still have to clean it up. I haven’t found any body who is remanufacturing these, so good luck. The filler neck tank seal. Remember this CR20B Tank is NOT intended for a 1965 C Body Polara/Monaco/880, but it does fit. So, remembering that you have to order the tank seal for the CR20B tank which again is suppose to be for a 67-68 Newport. Found that tank seal on Filler Neck Supply Company Online. It fits the CR20B Tank, the old Monaco seal I never tried getting it out of the old tank. Think it would have just crumbled, it was dry rotted from age. Again, you don’t want leaks. Think it was $12.95.

1966-1976 Mopar C Body Fuel Tank Grommet Filler Neck Seal

Hopefully this information helps everybody out there in my shoes and I’m sure many 65-66 C Body Polara/Monaco members could benefit from this information.

The last thing to cover is the tank mat. I realized that the OEM mat was just trashed. Then when I thought about it, I figured it probably has asbestos in it. I don’t know that for sure, but I’ve been around enough of that stuff to know to just leave the OEM fiber mat alone. Not sure if anybody knows for sure? I’m probably just going to put a thin rubber mat in there for the new tank to trunk pan spacing. FYI. The old mat did its job, you can see how nice the OEM trunk pan looks in this car from the pictures.

So far, I’m only in this about $750.00 dollars or less for this HUGE update/upgrade. I recommend that if you are tackling this job not to be worried. It’s possible and you will be extremely happy you did it, for safety reasons if nothing else. Stay tuned, for more updates as I work on finishing the install. I am still not done everything but am real close.

Please provide any information, experience, or thoughts you may have so we can put this whole thing to rest altogether for fellow members. Thanks!

OK Little Pete,
Is this thread still live?
I'm working on replacing the fuel line on my '66 Monaco. I read your description, but you never got into how you replaced the section that goes into the frame. That's under the passenger door and then out in the engine bay. How did you place that section?

I took a stiff wire and taped it end to end to a new piece of fuel line and poked it into the frame from the back side while an assistant was watching for it on the other side, grabbed it with a pair of pliers and then pulled it though.

You know those plastic signs that people are planting on street corners for all sorts of crap (like "we buy homes" or "$10 IP TV") - I pull them up when ever I find them near me. They have some nice steel rods in them, you straighten them out, it's about 5 ft long, maybe 1/8" diameter rod. I used one of those to fish the gas line through. I'm using the copper-nickel 5/16 line, I bought a whole roll of it (15 ft?) because I also used it for the transmission cooler line to the rad.
