2001 Silverado Z71...5.3l, 4T65e, auto 4wd...regular cab, stepside...209k miles My fuel pump started whining on me today. Happened suddenly...no whine yesterday, very distinct whine today. I can only assume this means it is about to fail. Since I rely on my truck, I have to at least be ready to replace it (if not replace it before it leaves me stranded). So...main question...what is the easiest way to get to it? Move the bed out of the way, or drop the tank? A bit of background might help here. It spent it's early life in Michigan before I moved down here to NC...so it does have it's fair share of rust under there. I didn't have any issues with broken parts when I did the tranny a couple months ago, though. As far as equipment...I have an A-frame with a chain hoist, cherry picker, a plethora of jacks (including a high lift jack and a motorcycle jack), and air tools. I tend to find myself doing these projects without an assistant. Second question...is there a cheaper way of doing this? The fuel pump and sending unit seem to be sold as a single piece, which makes the price skyrocket. Is there a way to dissect the unit that is in there and just replace the pump with a Walbro 255 (or other non-original pump of an appropriate size)? Third (and final) question...assuming the answer to question two is "nope", what is the most reliable brand to replace it with? I have found that buying the better parts pays off in the long run. Are there any pumps made in the USA? I can even accept Mexico, Canada, Japan...but please don't make me put Chinese junk in my truck.
