Help with fishing wires through conduit

Tyring to fish new wires thorugh a 100" conduit run. I can run the fish tape about 4-6 feet from the end going in either direction.

I have tried lubricating the fish tape as well as using a nylon version hoping it would have less friction and make it the whole way.

I also tried using a shop vaccum and sucking a string through, didn't work.

Rather then digging up the 3' deep conduit, is there another option to get the tape through? Maybe anther tape to catch the one that is 4-6 feet short? If so how would I do that?

Thanks

Yeah, I'd push the first one as far as I could and then try a second fishtape from the other end to try and grab it and help it along. Get creative making some hooks & loops!

Fish tape to fish tape

Try to push one tape as far as you can, be sure it has an open hook on the end, then do a small ribbon type bow on the end of the other tape made from a long pull line. Push the second tape in as far as you can 'till it hits the end of the first tape. Then remove the first tape with the ribbon attached. Remove the second tape and use the draw line to pull a heavier line to pull the wires.

What problems did you have in trying to suck a string using a vacuum cleaner? Did you use a mouse on the string? I usually tie several lengths of cloth depending on the size of the conduit, then sucking it is not a real problem. Sucking a string alone won't work.

What Chandler said; I've used pieces of plastic grocery bags since they're to light and airtight compared to cloth tied to 50 lb fishing line. Good luck.

if sucking a string is too difficult for you, you have either two problems neway 1-no head made on end of fish tape(bent over) 2- wrong size head on fishtape, if your head is too big it will have trouble being pushed throught the last 90 as well with no head. if the end of the fishtape is cut, come back about 3/4" grab it with pliers bend it back with about 1/8' gap between what you just bent over and the before bent tape. with the hook facing down. from the end of the tape come back about 2" and barely tweek it up(bend it back just a hair) this should make the hook look in line with the tape. take electrical tape and rund some tape over the hook to prevent snagging. should push through.

I am assuming you mean 100' aka one hundred feet.
What is the nominal size of the conduit?
