No worries. The sock is just the strainer; the fuel will go through the pump anyway.

You are good.

FWIW, it's been two years since I changed my fuel pump with a Walbro from Racetronics. First, the in tank part of my sending init was rusted, too. Even though it cleaned up pretty well my feeling was that it will just quickly just rust again. So, I replaced it as well as the seal/gasket. Second, after my install, no start. I removed the new pump, began looking closely at the wires and I discovered that the positive and negative were transposed. I never thought to check before installation, I just assumed they would be correct. I had to remove the wires from the supplied connector, reverse and replace in the connector. Instant start. Lastly, Unless your tank is spotless, I suggest using a vacuum extractor and sucking your tank dry and any debris in the tank. It's not worth the few bucks worth of gas to risk that debris mucking up the sock. Well, that was two cents worth. Good luck!

I don't think you hurt the pump but why is it smelling like gas? Regardless of whether I put the sock on or not, if there is a gas smell and you just pulled the pump, I wonder if you sealed it right? Was there a new gasket or did you reuse?

This is worrisome. Did YOU flip it around or did they?

New RX brand pumps they do tell you to flip the polarity on some of them. Why they designed them this way I do not know.

It was smelling like gas because all I had was a towel over the open fuel tank. So I before I left to work yesterday, I put the pump in the car and put the gas cap on. Just to eliminate most of the smell

Racetronix is sending me another harness, free of charge. Hopefully I get a good one. Also asked them how much for just underside tank connector.

Kinda risky As I imagine my system only vents IF the tank pressure reaches a certain amount. You can have way more evaporated fuel at atmospheric pressure than at several psi. A spark and "BOOM". I hope they send you a new tank pump gasket. Like condoms, I don't reuse gaskets. Maybe if that are designed for multiple installs but even that is uncomfortable for me.

So I told racetronix I needed a new in tank(bulkhead) connector. And they sent me this. It has 4 pins, instead of 3. Doubt it'll hurt anything, but just curious as to what you guys think.

I dunno.... Will it work? What does the extra wire do?

I'm not even sure myself. Will mess around with the car tomorrow, and see. The one they sent me has a very different shape compared to what is on the car.

So no, it will not work with the car. There is a 4 pin connector on the outside of the tank, and it goes to the connector with the pins that are slightly burnt. There is no to disconnect it, unless you snip the wires. So my choices are: a new fuel pump tree for $300 at the dealer. Or(and I just noticed this) buy the outer harness in this pic from racetronix. The connection will work with the new in tank bulkhead connector they sent me. Would it be stupid to buy a new fuel pump tree? Mine is rusty as seen in pics.

Did they send you the wrong connector?

Can they just take that one back and send you the right one?

I would never want to spend someone else's money (my wife does that for me) but you are rapidly approaching the RTFS moment.

And I would be mildly furious with racetronics over this.

It seems like you've spent a lot of money and all they have done for you is send you inferior parts, defective parts and incorrect parts..

Furious would be a good start.
