Okay guys here are some news...
I ended up receiving the correct sending unit...it's really identical to the OEM so it should be good!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
It arrives exactly in its place in the bottom of the tank
I made myself a small gift: a brand new 20gal air compressor...very useful for cleaning fuel lines with compressed air
I replaced all the rubber fuel lines: two vent lines on the tank, one between the car and the sending unit, one in the middle of the main steel fuel line at the passenger door, one between this steel line (exiting in the passenger side frame rail at the firewall) and the fuel pump, and one between the fuel pump and a copper fuel line just before the carb
Before installing the new rubber lines I checked and cleaned all the steel lines with the compressor, they were full of old rotten gas but they seems to be good, I didn't find any hole and air came out at the end of each line
Then I installed the new rubber lines and a new fuel filter between the pump and the carb
Installed the new fuel filler neck seal, not the same that the original one but it works
Installing the tank alone is no easy task but with a second jack I succeeded![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
The fuel filler neck freshly painted (3 coats of primer and 3 of gloss black paint...I didn't know what was the original color
)
By hitting the filler neck to return it to its place in the tank opening I realized that there was still rust in it and it had just fallen into the tank![BangHead :BangHead: :BangHead:](https://www.forcbodiesonly.com/mopar-forum/styles/default/xenforo/smilies/BangHead.gif)
The radiator shop sandblasted for me the filler neck but there is a little part inside which they probably didn't manage to clean completely
I vacuumed what I could with my Shopvac vacuum and the long tip, it should be okay...anyway any dirt that may remain in the fuel system should be caught by the filter, which I plan to replace after one or two starts (I have a second new one for this purpose)
Anyway I have other problems at the moment: the car doesn't start at all...
I put about 6.5 gallons of premium gas in the tank and tried...the old battery (contrary to what I thought) doesn't weaken but the gas doesn't arrive at the pump...or at least at the filter after the pump
There is no plugged fuel line, they are all either clean (steel) or new (rubber), the tank is new, the fuel sending unit is new
You immediately think about the pump but it was working very fine 2 weeks ago, the engine was running...until the fuel can from which the pump was sucking gas ran empty
Probably the pump has sucked in air, apparently it may be necessary to prime it in these cases...what do you think of this method? Is it good?
How to Prime a Carburetor and Fuel Pump
Obviously it would be easier if the pump had a manual "lever" to prime it but it's not the case on a C-body (and other old cars like this I suppose)
I made two videos of the "cranking", I could upload them if it could help but basically the starter cranks but we feel that the fuel doesn't arrive, I filmed the fuel filter we see that nothing happen
It's not like the car hadn't ran in years, the pump, all the ignition system and the timing were good 2 weeks ago, the car was running with the fuel can, so I don't see what it could be except for the pump priming, I'll try that soon but if you have other ideas please let me know!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
