Alright I'm changing my fuel pump and I have it out right now. I pulled the assembly out of the tank a little too hard and scratched some rubber off of the brown/black wire that connects to the fuel pump inside the tank. Do these two wires have power going to them??? Im scared to start my car now in the fear that we might blow up... This entire plug with these two wires is completely submerged in gas when they are in the tank so there can't be a current can there? Need a response soon guys, thanks.

gas is non conductive. So just them being wet with gas is no big deal. Check to see if it's a negative or positive wire. If it is negative it's no big deal. If it's positive then cover it with electric tape or something to keep it from arching against something.

Test what ever you use to protect it in gas to see if it's going to fall off once it's in the tank.

Its actually black and orange wires going to the plug from the fuel level sending unit. The orange and black wires both have a small patch of bare wire showing

This is not true. Negative wires can spark just as well as positive wires if it isn't in line with a breaker and sees a difference in continuity.

I said it wrong. By negative I meant grounded. I know there is a big difference. Would that be possible with a grounded wire also?

I taped it up and put zip ties around the tap. All of those wires are in gas so I don't think its going to hurt it. I mean they would all be shorting out all the time with them being in liquid right. Idk I'm going to try it if y'all don't here back from me my car blew me up but let's pray it dont

those wires aren't fully sealed to begin with. Besides, it's the fumes you have to worry about igniting initially rather than the liquid. As long as they can't arc with something else easily you should be able to go zoom-zoom rather than boom-boom

So far so good. I drove it down the road and it seems to have gotten rid of my hesitation in high rpms. I'm still a little scared, my tank is completely full right now but when it gets down low with the fumes is when I'm more worried. I put black electrical tape around them and them put about 5 zip ties over the tape to hold it in place. I just hope the gas doesn't eat through the tape and ties and start arching. Idk if those wires have power to them or not. Its for the fuel lvl sending unit so they may not have a current at all...anyone know?

The system measures Ohms resistance from the level sensors to determine fuel level, but I'm not sure what voltage.

Technically yes, it is possible.

the only way that's possible is for the ground/negative wire to lose and re-make contact, a spark would in theory only happen then.

that's correct.

I still felt unsafe with just electrical tape and zip ties covering the bare spots on the wires so I picked up some jb water weld, some rubber gas resistant self sticking tape, and some plastic wire loom holders and put it all together. Put the water weld which says is fuel system safe on the wires then a layer of the rubber self adhesive tape then the plastic wire loom and zip ties on top of that. If it ever sparks or comes close to contacting each other now then it was meant to happen

you should have put the Tape then water weld then another layer of tape. The water weld might get in between the wire strands and cause electrical problems.

KaLiKoStreet

The bare spots on the two wires are smaller then 1 millimeter. And its to the gas level gauge so I should know if it starts having problems. The tape would have been sort of hard to get on there tight enough, its some strange stuff its not sticky to your hands you have to stretch it out while your wrapping it and when it contracts back down it seals to itself. But with the layer of water weld on first I had a thicker area that I could wrap the tape around more tightly.

Im pretty sure im familiar with the tape. Self vulconizing rubber tape. Its good stuff. Turns into a solid piece of rubber over a few hours.
