Fast delivery and good product for the money. All pieces available for the job and good instructions for installation. although I didn't need the instructions it is very helpful for those who do. I put this on my 2000 Silverado and it worked great. A quick note. if you don't have a fuel line removal tool, you will need it for this job. Mine required 3/8 and 5/16 removal tool that I already had. It will make it much easier to install. One other note. If you have mostly good lines and only have to install from the tank to the good lines, the tube they send is compatible with brass compression fittings.

This was an easy replacement for my rusted out lines on my 2000 Silverado 1500. I removed part of the old lines, but left most of them. I have done quite a lot of work on my vehicles but never fuel line work. It was easier than I expected but messy.A few tips:1) Get a couple of brass vinyl to vinyl compression fittings for the correct sizes. Amazon or your parts store have them. They're cheap. I couldn't get the old rusted fuel line out of the connector on the tank side so I cut the vinyl line behind the quick connector and used one of these instead, it was quick, easy and reliable. Same for the eval line on the engine side, way easier than the odd little tube with this kit.2) Start at the front of the line and work back. It's a lot easier to snake the lines down than up because the lines are rolled up and hold the curves while routing them, and I would rather cut the lines down and have a splice under the truck by the fuel tank than under the engine above the exhaust headers. You will have to cut the lines down because they're too long, which is a good thing, makes them easier to work with and they come with fittings for shortening them.3) Plan 2 or 3 hours, it took me longer than expected.4) If you're comfortable with it, drop the front drive shaft. It's not hard and makes it a LOT easier to route the lines securely up and away from exhaust or drive shaft. Otherwise you're trying to sneak your hands up between stuff to get them zip tied in the right places.I'd do this over the steel lines every time. Good product.

Replaces only the steel portion of fuel lines.Reasonable enough to install original fuel lines not as fun to take out. Make sure to read directions beforehand! Removed my bed and didn't have to. I used split wire loom tubing so the fuel lines stick together and stiffen them up and you can zip tie them to stuff. Fuel lines are in coils and are naturlly curly. Quick connects worked well. I am not a mechanic but do own stuff.

These lines worked great for my 2003 Silverado. I do wish the instructions were better 😪 but if you take your time you can figure it out no problem. Some installation tips I have are: 1.) Do not expect the existing lines to separate easily at the fuel tank and plan for this with some new quick connector fittings or at least some new fuel line retaining clips. 2.) The new lines are longer than needed. Just cut them down and use the included quick splice to shorten. 3.) Have some cv joint boot clamp pliers handy to crimp the new clamp onto the existing evap line. 4.) It seemed impossible to remove the existing fuel line sections above the transmission. I just cut them off and left them. 5.) Get some split wire loom for the new lines and put it on the lines anywhere it may chafe the vehicle.

This ended up being a very long project, mostly because the connectors don't match the ones from my 5.3 L Vortec to tank on a 1999 Silverado 1500. The installation is not intuitive, so some instructions would've been wise to include. The filter came with opaque/whitish plastic connections that didn't fit anything from the truck or from the kit. I had to contact the seller to find out that those plastic pieces are not supposed to be on the filter, they just happened to purchase bulk filters that were made for another fuel system, altogether, so he told me I had I break them off in order to connect the fuel filter. It came with unnecessary parts that need to be broken off in order to use it.... they should've been removed before placing them in the kit or at least have INSTRUCTIONS THAT SAY THAT.
