Fuel Sender tank vent line, under vacum?

[Speedtrapped]

Discovered my fuel sender tank vent line was rigged w/ gasket make as 1 of the last 2owners before me(not Alan, he doesnt wrench) snapped the nipple off in the connection. The gasket maker was dissolving and literally loose, evidenced by dried fuel on top....is this line under vacum?

The fuel sender line is under pressure when the pump is running.

I'm not sure if the 996TT has a return line, some of the older NA car have a return line as well.

On most cars, there is also the vacuum line from the intake manifold for EVAP compliance.

It would be a good idea to repair the broken connection and check for leaks before assembling everything again. You DON'T want fuel spraying all over the place..

I dont think that is quite right???? look at pic, there is a pressurized line out, and a return, then a vent line(the hack job that has what looks like mollasis all over it, but is gasoline stained silicone.). I thought fuel vapors vent out of this line? and when engine reaches operating temp, a vacuum is valve opens, and pulls vapors back into engine??

sorry, had trouble uploading pick of the top of my fuel sender.

here ya go....

OH gosh. Wow. That looks safe.

Yes you are correct about venting the vapor back to the combustion chamber, from what I understand.

A couple things I don't like messing with. There's no good reason someone did that.

1.) fuel and fuel vapor and air conditioning gas.

Does the vent line or connector look damaged at all? If so, maybe a good idea to replace that (and maybe the hose too???)

Do you have the DIY for the level sender (I think the fuel pump DIY here or maybe on Pelican has it).

Once you have the new sender in it has to be calibrated with a PST2 or PIWIS (something I need to do as well once I can afford a new sender).

I was blown away someone would" fix" the broken nipple thi way....I was able to crazy glue nipple back on, and attach vent hose properly....I ordered the sender from pelican, comes wed. I know the bonding glue won't hold up to fuel vapor, but I am hoping it can last till we'd. I read the DIY, actually I was checking out my fuel pump, and in process saw the hack job.

Yes that is the vapour line for the EVAP system which is under vacuum at certain times controlled by the DME as a duty cycle. Unfortunately I seen "repairs" like this before and you're right to replace the unit. You didn't have a check engine light?
