Soldering Fuel Pump Wire- Bad Idea?

Has anyone ever had the end of the wire going to their fuel pump (the actual connector) corrode up and break? What did you do to fix it? Last year, I was having issues starting the truck and keeping it running, because the fuel pump was intermittently getting power. I had traced the issue all the way back through the system to inside the fuel tank. I had assumed it was the pump itself, but I was wrong. The contacts inside the plug were so ate up with corrosion that it had sorta fallen apart. So I had cleaned it up and stuffed the connector with dielectric grease to insulate it and keep it from moving around. That fix worked for a year, but now I am having the same issues. I have not completely diagnosed the issue, but just in case it is that wire again, I wanted to seek some advice on how to combat this. Has anyone ever just completely cut out the connection and soldered the wires together? If so, what did you use to seal it? I believe the gas would eat electrical tape, but would it eat heat shrink? I would be using the little metal butt connectors like these:

So has anyone done this? Do you recommend it, or is there a better way to do it? And how did you seal the connection from further corrosion?

Thanks for reading,

Soldering is fine, as is simply replacing the connector. But replace it, don't try to clean it up. Once it has started corroding, stopping it is just about impossible. Just use dielectric grease on the new one and corrosion will be a thing of the past. Heat shrink is the only way I would insulate the connection however, if you choose to use solder. If tape peels away, you can have a short in a bad place.

 

Thanks for the reply!
I'll definitely replace it if I can find a matching connector- where would I get something like that? Only time I can find them online is when you buy a whole new fuel pump, and my fuel pump is still good. Only a couple years old, installed it not even 20k ago.
I have been leaning towards heat shrink, but I don't know how it would react with the gasoline.

 

Pic of connector?

 

I don't remember exactly what it looks like, will have to take a pic this weekend, when I drop the tank and pull the pump. I guess it has to look something like the one in this pic, don't see why it would be different. But I'll still take a pic when I get it out, because it may very well be different.

 

You can buy the connector from Toyota then just crimp on new pins

You also might be able to remove and replace the pins on the one you have.

Are both sides corroded ?? Then any two conductor weather tight connector should work.

Look for heat shrink that is safe to use in gas.

 

Yes, both sides were corroded, one side more so than the other.
