Genuine GM Block Part No. 20777935

What I liked is my car is back on the road. Installed easily enough in my 2008 Buick Lucerne. It came with a low profile relay for the fuel to reduce the chance of sitting over the box and crushing it

Here are some pictures of what it looks like. Worked like a charm. Very easy to install.

Part is as good as GM makes , it does have improved shorter fuel pump relay. This is the second replacement in my 2008 Lucerne since new. Fuse box looks good enough, problem is they stuck it flush under rear seat where large passengers and heat contribute to it's failure. GM auto design cost me hundreds of $$ and this rating 2 stars.

This item is very well made and it works very good.

First the good: this came with all the relays and fuses, including the new short fuel pump relay. This is the rear relay box that goes under the rear drivers side in a 2008 Buick Lucerne, (or similar vintage Cadillac.) We bought this to replace the burned out box from the too tall fuel pump relay, (Google the recall.) This is a beautiful OEM quality part made in Mexico. I had emailed the company that I would like to receive it earlier, and they sent it right out, so I did get this several days before it was promised. 🙂 This part came packaged nicely too. Now the bad: this description needs a picture! Seriously! The part number is different than the one the dealer gives you, so we need a pic to make sure it's the right part. The part number from the dealer that matches this part is #84446208 and our quote to buy from the dealership was $304.07!

Pretty simple plug and play. Comes with the shorter fuel pump relay so the seat bracket won't put pressure on it which caused my original fuse block to fail. I replaced about 2 months ago and haven't had any issues since.

It was a direct fit. It also comes with the shorter fuel pump relay that will fix the problem of the longer one shorting out because of the fitment of the seat pushing the fuse box.

Fixed my 2008 Buick Lucerne fuel pump relay fuse burnout issue. Easy to install. Just watch a couple youtubers do it and then you can do it yourself 👍🏼Been in the car 2 months now without any problems. I also cut the seat bracket as suggested.
