Is a hot wire kit necessary for one walbro 450 02 silverado
 

My truck was running for 2 days great then out of no where it cut off on me.let it sit for a little bit then started back up then died again in like 5 seconds.Fuel pump cutting in and out

Yes. The 450 draws way more power than a stock pump and will melt stock wiring. You may also have a hose failure if you didnt use the right hose.

Like Richard said, a 450 draws too many amps for stock wiring. Esp for an 2002, in 04 they started upgrading the bulkhead connector but the wiring still is too small.

Ok well I guess I gotta buy one what happen was the install kit I got came with a connector but the rubber swole up and pushed it apart I said to help with it and solder the wires together.Any recommendations??https://cimg1.ibsrv.net/gimg/www.per...8d0a4d0a5.jpeg

ok thanks for the reply where would be a good place to buy

You'll likely be right back under there soon, give you a chance to fetch up a couple good fuel injection hose clamps, and a foot of SUBMERSIBLE FUEL Hose... Keep that, and your tool box in the truck with you.

Thats a transmission fluid rated hose, not a submersible fuel one. You need something in accordance with SAE 30R10 spec, like this:

dammit ok thanks for the heads up

thanks for the link I need to do that today this is my daily,hope I can find some local.How about the soft line coming off of the fuel rail on any gm car the soft rubber hose before it turns into a hard line I work at a salvage yard maybe I can find some laying around.and normal hose clamps are no good?

Hose HAS to be submersible!! If you use “ soft hose” as mentioned the outer shell of the rubber will deteriorate quick as hell inside the fuel tank. Those types of hoses have a special inner lining and a plain rubber on the outside. It can withstand normal elements but it wouldn’t survive inside your tank. The gates hose that Atomic mention is a cheap $20 piece of mind and it comes in a foot per package. Most parts stores don’t carry it and needs to be ordered online. I have been using that hose for years as my Go to hose for doing fuel systems. Never had any issues with it. And did you zip tie the hose to the barb ?! It’s better practice to use fuel injection hose clamps as they are smooth in construction as opposed to standard worm gear clamps which tend to cut the hose and not seal in a “perfect” circle as the fuel injection hose clamps
