how did you redo the wiring for new fuel pump?

[jt15833]

I got a walbro fuel pump and I know you have to splice the walbro plug to the original 2 fuel pump plug wires so that it hooks into the walbro. Im paranoid about doing this the wrong way and having the fuel tank blow up. it came with some rubbery coated crimps but i dont really want to use those for a job like this. is heat shrink gasoline resistant? anyone got other methods / input on a situation like this. am i worrying for nothing?

use the butt connectors, something about the gas and solder dont mix if i remember.

i dont remember the wire colors off the top of my head just start the car and backprobe the connector to see which one is power (battery voltage) and what is ground.

gasoline is not combustible on its own but rather the fumes.just use the butt connectors and look at the stock pump when you pull it, its already marked postive and negative.

if you don't trust the butt connectors just splice the wires and give it a good wire twist job! Make sure u wrap it good n tight with electrical tape.... DONE!! Some may disagree, but thats how I did mine and it runs like a champ!

Electrical tape????In your gas tank??

You know that Gas will eat plastic and melt that glue like nothing right.

I hope you didn't do that on your car

ive had it wired up for a while im just wondering the best way to secure the connections safely. solder + heatshrink would seem to be the best but would there be any issues with the gasoline?

for the 3rd time

use the butt connectors. do not solder.

Couldn't that also be a prob w/ the butt connectors? Couldn't the gas theoretically eat through the plastic?

no, your gas tank is plastic.

thats why they give you butt connectors.

the way I look at it... when I install it, I'll make sure I do it exactly as the instructions say.... if it blows up and I survive, they'll be buying me a ferrari, funding my business plan, and giving me a nice retirement fund.

but if I don't survive then my family gets to have all those things. lol

Fuel isn't a very good conductor of electricity. Use the butt connectors, I did mine 3 years ago and no problems. The fuel will keep the connection from corroding.
