Ok I just installed a gas tank that is a near to new as a used tank can get, (thanks Jim Pllard!), any way I have a new carb to install but am being very cautious in installing the new filter and carb, I tried turning the motor over to try to get gas to flow up to the fule line going to the filter, and nothing is coming out, before replacing the fuel pump I wanted to know if there is another inline filter I should check? When I tipped the old tank I could hear chunks of rust sliding around, is it possible for the fuel pump to become clogged? Any suggestions? if I have to replace the pump is there an electric pump alternative ( 250 - 6) , and how costly are they? Could the fuel line itself get clogged by rust? I want pure gas coming up to the filter so I don't have to replace it several times. Victory is in sight, I would really actually like to get this carb installed and drive my car someday.
You could always hook a vaccuum pump up to the fuel line and see if gas comes through ... I have a pump that came with a cup to use when vaccuum bleeding brakes .. that should work. Also make sure you have atleast 3 or 4 gallons of gas in the tank .. I just installed a refurbished tank and new lines and fuel came through with minimal cranking of the engine ...
gas flow Do you mean to disconnect the line going into the pump? would a vacuum line hooked up to the outlet side of the fuel pump pull gas through the pump? I will make sure there is more gas in it, I used a six gallon tank but I don't think I poured the whole six gallons in, I does it hold around 4 gallons even when the car is "out of gas"? The back of the car is on a very slight down hill too, I will try that thanks for the tip, do you know anything about electric pumps?
oops well I certainly am not going to hook a vacuum LINE to the fuel line!! sorry meant to say vacuum pump
when i did my"big" tank swap my rubber hose at the sending unit was stopped up. i also primed the fuel pump. i shot air from my air hose into the filler neck of the gas tank untill gas came out the feed line at the carb. it worked for me. good luck...frank...:bananaman :bananaman
What's the big deal about hooking up a vaccuum pump to the gas line to pull some gas through? If it can pull brake fluid it can pull gas ...
If I leave my old truck sit for more than a month with less than a 1/4 tank of gas - all the fuel in the line and pump runs back into the tank. There is a check valve in the pump that is supposed to stop the pump from loosing it's prime, but over time it bleeds off or maybe just faulty. When this happens - I pull the line coming from the tank at the pump. Then I take the fuel cap off and put the blow gun on my air compressor. I sort of cup my hand around the blow gun and fill tube and hit the air to pressurize the tank. This will force the gas up the line. I look under the truck until I see fuel hit the ground and then I throw the air hose down and quick push the hose back on the pump. Cleaver PS youre going to puke about a cup full of fuel doing this - so dont do this inside or near flames.
Prime the motor by pouring a little bit of gas down the carburetor,or use starting fluid...just don`t use too much.The motor should run long enough that way to get the fuel pump to start pumping the gas through the lines again.Same ggoes for when you run your car out of gas and can`t get it going again.
that's what I had to do when my brother robbed me of all the gas in my Mav's tank....add 5 gallons to the tank, prime the carb, start it...and keep it running on carb cleaner until it started to stumble. Took forever, but finally got it going. I bet it ran on carb cleaner for 5 minutes, or so it seemed
IT IS ALIVE!! HAD A GREAT DAY after priming the fuel pump got the Comet running today!! actually drove it !! it sat over a year started and it had absolute no blue smoke.. must have been well cared for in the 72k on the odometer.!! :bananaman :bananaman :
