Create Tar file in unix and split it to smaller segments

I need to split a large tar file for backup purposes on a unix system. I need to tar the /u/appl directory and then split into chunks less the 2gb in size. The following command is what I'm using now, but I get an error "Split: cannot open input".

tar cvf - /u/appl | split -b 1500m /u/backup/appl.backup.tar.gz

I'm sure there's a syntax error, as I can run the tar command by itself with no issue. I've tried to resolve but haven't been able to.

does stdin use temp space on /dev/root? That looks to be the case as I'm running into a space issue in my test environment. Can I direct the temp storage to /u somehow?

stdin/stdout do not use intermediate (temporary) disk space.

Thanks gentlemen, got it sorted. Could've solved my problem with the info from nemws1 alone, but I greatly appreciate the extra info from woolmilkporc and I used it to implement a better solution, so I split the points. Thanks again.
