🛢️ Fuel Pump Assembly E3556M for 2003 Cadillac Escalade ESV, 2002-2003 Cadillac Escalade EXT, Chevrolet Avalanche 1500, Suburban 1500, GMC Yukon XL 1500 - TOPSCOPE FP3556M Review

What I like most about this fuel pump is that it works and fits my 2003 Chevy Avalanche just like the OEM. 5 times cheaper than other manufacturers with the same results. IT WORKS!

Judging by the reviews, it's happiness. Mine was a failure. Installed on 03 Suburban, not bad, but the pump doesn't work, the transmitter doesn't work. I checked the wiring again (others said they were wired wrong at the factory), bench tested the pump and transfer unit, nothing. If you pass the pre-installation test.

Works great so far. Doesn't require flashing. The hardest part was resetting the tank as it was almost full when the 17 year old factory pump failed. The price and a few negative reviews sucked, but the free money-back guarantee made the decision easier. In no way do I recommend this task to a hobby mechanic. I will update this review if there are any issues.

I have 02 Avalanche Z71. The pump is screwed directly and fits perfectly. The supplied connection diagram with the pump and the pigtail did not work. We had to pull the pump back out and trace the lines from the fuel gauge and from the pump to see which lines go where. We had to cut the plug and hard wire the pump. After that everything worked correctly. If the chart was correct I would rate it 5 stars.

Used this in my 2003 Escalade EXT when my original pump died at 140,000 miles. Fits perfectly and works great. If you are doing this work yourself, you should also consider ordering replacement fuel lines. Also remember to set back and disconnect the fuel vaporizer (carbon canister) as you will need room to move the fuel tank around a bit before lowering it. Most importantly, don't forget to disconnect at least the smallest atomizer line before dropping the tank, otherwise you may (like I did)…

I can't believe what I had to go through with this crap. First, my Suburb 02 had the wrong wiring harness connected, but the box had the correct one for me to connect. No problem, I'll do that. I put the adapter in, plugged it in, but it won't turn on. I sat there for hours fiddling with the wiring and couldn't figure it out. The next morning I go to the parts store and pay a little more for another fuel pump just to see if that's the problem. I had to plug the old wiring harness back into the…

Ordered in August 2020 2002 Chevy Avalanche Z71 5.3L Local price for a pump was a few hundred. I was very hesitant to order this based on the price and some reviews. Most of the bad reviews seem to be related to the electrics. Before installation, I checked the wiring and compared it with the existing device. The only wires that didn't fit were the wires to the pressure sensor. I don't know if this makes a difference unless I swap them out, but I ended up moving the wires to fit my existing…
