If you’re not cleaning & painting them and putting them back in, then scrap value at your local scrap dealer for the various metals is about the best your going to do on common pump guts.
Contrary to years of accumulation in the picture, I do leave the guts in a lot of my pumps. If it’s a rare pump, I always leave the guts in to preserve the history (just my preference). However if I’m restoring a common pump for someone and they don’t want the guts - out they go. You have a common pump there.
Below is a picture of a gut pile in the back of my truck I took in for scrap. However, to Gas Pump Rob it probably looks like a murder scene.
