fuel line or gas tank?

Question

ok, so the car (64 corvair) has been sitting for 31 years with a half a tank. so expired gunk gas was expected. i tried to cyphine the tank but only a quarter came out. i was advised to disconnect the 2 line to the carbs and turn the car over, letting the pump pull it out and drain into a bucket.well doing so i the 2 lines (rusted) ripped in half, fine, mkes it easier to drain. i began to trun the car over, nothing. i then disconected the line and took a vaccum to the line hoping, nothing. i know there is a mesh screen in the tank. could that be clogged with garbage, or could it be the line clogged with garbage. if the tank, how do i remove it. its in a front "firewall" position. how hard to replace the line. in any case trying to bend a straight piece of tubing wihout a kink through the rear firewall isnt going to be fun, can i use a rubber line? or should i just push it over a cliff?

Answer 1

If the fuel line is rusted that bad, it may also have rust holes in it elsewhere. This would explain why you can't get a vacuum to pull the fuel out. I would suggest removing the tank, and cleaning it out, because there will be rust inside of it as well. Future problems will be had if the rust is left in the tank. There are companies that make replacement tanks and straps for the Corvair, just like other antique vehicles. Just have to Google them or search on Ebay. I would suggest replacing the fuel lines with new tubing, you could repair with fuel hose and double clamp the ends, with the screw portion of the clamps opposite each other, but there still is the question of the integrity of the rest of the fuel lines. Just wait till you get to brake lines and seals, that will be your next hurdle.

first off, if the car has been setting for that long do not turn thecar over, first, get as much gas out of the tank, then cut or break the lines at the tank, try to loosen the gas tank straps if they wont loosen wd 40 them and wait a bit then wire brush them then wd 40 again do this till clean or if they are so rusted your buying new ones anyway cut them off with red handle tin snips, once tank is on the ground pull the pick up tube out you wont to put this insome kind of b-12 or similar substance leave a few hours or longer till you can use an air gun to push out the sludge that has built up in the tube while you are waiting for that check the bottom of the tank for any kind of corossion inside rust,flaking etc. dump it out while slapping the outside of the tank if still ditry fill with b-12 or other and swish around then dump it out again should be clean enough, reinstall the pickup tube then install the tank in reverse order of removal, I would use the gas rated rubber line make sure you dont kink it & these lines generally last a good 15 + yrs use an in line filter before the pump to catch any left over particles you may have missed when it is timeto change it you can remove it & replace with line or add a new one also put one between the pump & the carb aswell as in the carb gas inlet if available, if all the vacuum lines are connected or capped off poor a little gas in the carb make sure that it fires over, probably after changing all the plugs & wires, if it fires then crank the engine at five second entervals till the car trys to fire again,then once you know that it will start up poor three cap fulls of dextron trani fluid down the carb this will make the car smoke abit but that is all the carbon and junk burning off the inside of the engine when it is done smoking the car will run like it was designed to, You will need to re break the engine in with break in oil for the first two oil changes at maybe 500 to a thousand miles apeice then fill with the standard 20-50 oil (Texas) or best blend for your area keep a check on the inline filters freqently to keep them fresh ( use the clear ones so you dont have to take them off as much & just by the replacement inserts alot cheaper over long term) break car in at 70 MPH like when it was new. You should have minimal problems with this car if you follow thes instructions.

Good luck

drop the tank and take the fuel gauge out of the tank let it soak in kerosene and drain the old gas out. when done with all this remove plugs and put a small bit of oil in each cylinder. this when the engine is turned over you build the compression back up and it will start a lot easier.

Answer 4

i own a repair shop,,and you probably will have to remove the tank from it and flush it out really good and turning the motor over didn't help it any at all,,now your going to have to clean all the lines out,and as for the part of the line that is rotted in to, you need to replace it with a metal line,you can buy a cheap line bender to do it with,but i wouldn't use a rubber one on it,,not in that spot anyway,i have restored a corvair before,,you,ll have to completely remove the tank,and id say your going to find a lot of rust in it the tank from condensation over the years,and it will be hard to get it all out of it,,and the filter on the end of the line in the tank will need to be replaced on it,,its going to be hard to get it started after all these years,but you will get it going,,,good luck with it,i hope this help,s.

Answer 5

If the tank had gas in it for 31 years the gasloine has "gummed". It literally looks like strings of gum. If this got into the fuel line it would be clogged, along with anything else that would clog on strands of gum.

Answer 6

by skill of format, a filter out restricts move. it truly is the way it captures impurities, no undergo in recommendations if or no longer it really is in air or fluid. I ran a gas filter out on a street bike and spoke of no large difference in elementary performance, even at severe rpms. My adventure is utilizing an inline gas filter out had little or no important effect on elementary performance. by skill of nature, as a filter out thoughts up impurities, it really is going to start up to diminish again move better constructive than at the same time as it grew to change into into new/clean. So replacing/cleansing a filter out will be needed swifter or later.

Answer 7

I'd strip the whole car, replacing all elastomers and lines... 31 years is a long time....
