I knew Chevrolet started using that setup in 2007-2008, but I will trust you about the 2004 C-1500 using a single-line, in-tank fuel filter/pump. Rock auto shows external fuel filters .for that year, but who knows? I knew my 2015 Malibu had that set-up, and I dont like it. I am used to fuel injected heavy-duty class 8 vehicle diesel engines that always have a return line, as does my 1998 K-1500 Vortec.

I would have thought that the GM engineers would have understood that pickups get more dirt, water and sediment in the fuel tank, being used off-road and all, but I suppose not. I guess I will be keeping my K-1500 for a much longer time, since I can change the inline fuel filter, and being a 5-speed stick, I dont need to worry about transmission filter changes, as I do with the internal filter on my 2015 Malibu 6T40 6-speed automatic transmission.

My hat is off to you, Sir!

I wish they would leave things that work alone,if one of the one line system vehicles sits for a extended period,ethanol and moisture,yikes,youre going in the tank,way too soon

Speaking of fuel tanks, I have seen people cut large holes in the pickup bed, in order to change the fuel pump, without dropping the tank out of the vehicle. I've even seen a car that had that done to the bottom of the trunk floor.

Hell the way things are going, they wont even use motor-oil filters, or maybe even no motor-oil drains one day. They will be "permanently sealed engines", just like the new automatic transmission$ supposedly are (yeah, right). Once the engine$ burn out, and they will, you just have to have new replacement engine$ in$talled!

my 2004 Chevrolet Avalanch does not have an inline fuel filter. First one I've seen without one.
Did GM start this. Because mine has a manufacturer date of 10/03 which makes it an 04. Everywhere I've read they have one but mine don't. Mine also does not have a cabin air filter.
Has anyone else ran into this?

Yup worked on an late 03 and it was returnless also. No filter.
