Not this again.

Ls1's are returnless factory. You have a fuel feed line and an evap line.

Yeah, should be fine since it just connects to the solenoid on the fuel tank for the charcoal canister. Maybe just stick a plastic cap on it so you don't poke your eye out

Osha approved

Hold on; the LS1's aren't exactly returnless.

There's a loop of sorts from the gas tank to a tee fitting in the hard lines after the filter. The one side of the tee is fed from the tank, the other side runs up to the engine, and the side port loops back to the fuel pressure regulator in the tank, which vents excess pressure into said tank.

Unless you're running some kind of aftermarket setup?

That Tee fitting is what was talking about in my earlier post about the line branching off. I wasnt sure if that gets ran up front or back to the tank.

Ill have to just head back under the car and check

Crawled under the car to check everything out last night and i should be good to go. The line off that T is routed back to the tank hat and dumps into the tank. I will be okay just capping off that Evap line

Ran into another issue yesterday when i started to put my rad in. Realized the the harness for the electric fans that i thought was on the rad the whole time is actually MIA. In addition to that problem, i believe i may have hacked off the connector for them in my cutting spree.

- Anyone got a pic or any info of what that connector looks like so i can check? I believe the one that got hacked was 3 pin with fairly large gauge wires. I recall taping back a unoccupied connector yesterday with multipul pins (atleast 4) so im hoping that was it.

-Anyone have one of electric fan harnesses laying around ?

EDIT***

Was able to snipe this connector out of a pic in my phone, this is the connector i taped out of the way yesterday. Can any confirm this is the connector for the electric fan harness

[PolarBear]

Stock electric fan connector is 2 pin and is part of the body side harness from what I remember, goes to the fuse block

Really? I thought the fans each had a 2 pin connector of their own, which joined together at 1 connector. Something similar to this:

The harness I have from a 99 Firebird, the fan harness is not separate.

it doesnt have its own harness like this ? Or did this dude just cut the wires

[PolarBear]

Yes, the harness was exactly like that, but it was connected to the body side harness, no connector in the middle. I just found it on the harness, that big connector is there, but it is for something else, the wires from the fan connectors go down the harness. **edit I just toned it out, definitely direct from the fan to the fuse block**

Ill have to check it out when i get home from work, i remember seeing 1 stray 2 pin, but not 2.

Are you near the harness ? any way you can let me know what color the wires are?

Looks like blue and grey on one (might be green instead of grey, pretty sure it's grey though) and white and black on the other

Headed home to my garage now, thanks !

[PolarBear]

I should say, light blue and grey. I forgot there is dark blue too

[LS1ow]

Looks like I’m SOL. I don’t see any 2 pin connectors that would fit the rad fans(horizontal pins)

The only connector I see on the harness running across the rad support is the 2 pin for the washer fluid pump and the branch off on both sides for lighting wiring.

That 1 stray 2 pin I was mentioning earlier is a black wire and a white or faded yellow with black stripe

[PolarBear]

I could peel this one out of the harness if you really need

[PolarBear]

I could also make you some harness with 10 gauge wire as long as you need with the proper fan connectors at the end. This is what I did when I built the harness for my LS swap into my 92

[LS1ow]

Do T56 cars not have Electric fans? Maybe that’s why I can’t seem to find it

[PolarBear]

I think all the cars have the same fans for the LS years, V6/V8 and Manual/Auto

Found em. I’ve been swindled

And, where were they?
