Default Return Line Question

On a 99 ls1 camaro does the fuel return line just "T" into the feed line? I always hear "in tank return or returnless" but I always see a line coming off the fuel pump leading somewhere.

No it does not "T" into the feed line
The line coming off the fuel pump is the feed line
The line returns to the tank it the regulator.

Hmm ok. So the return line is not there... so only two lines come off a camaros fuel pump ...an evap and a feed line? I swear that the picture your showing me has a line coming off the feed and return of the ls1 pump assembly. Not saying its for an ls1 but your last sentence does confuse me... The line returns to the tank from where and a regulator would run in line with the feed.

There is a Tee in the supply line downstream of the filter.
This returns to the regulator mounted in the tank.

The sender has 3 lines, a supply, a return, & an evap line.
