I'm having fuel delivery problems. I've read every thread in here about the pickup inside the fuel tank and there seems to be several different types. Check valves, screens and no screens, plain tubes and ones with holes up off the bottom. Anybody know for sure? I'm going to drop the tank and have a look but would like to know what to expect to see if possible. I've already completely cleaned the sedimenter and with the tank drop I will replace all thel fue lines and clamps. Even the return line. Thanks for all the help on this truck. It's almost finished. I even found a brand new raido for it. I love this truck.

Ranger I gather? Fuel delivery as in starving? Pulling air? A vacuum gauge is indispensable. I ran into issues with fuel delivery on my ranger and eventually looked closely at the pick-up. I found a check valve gummed up with what looked like wire wool or metal shavings of some sort. I used a vacuum gauge to see that it was working correctly after the cleanout but I probably made a bad by trying to fish out the little stopper ball thinking it was gunk. whether or not this had much to do with the power loss I was experiencing isn't known. I suspect that it had less to do with this then venting problems. I see a lot of air out of the return line of the injector pump now, and if the truck sits for some time the first start is laboured as if having lost prime on the high pressure side. Not sure what is going on here but I fear that pump seals may have suffered for the restriction/lack of venting. When you drop the tank, plug the sending unit pick-up line and check valve and check for leaks with a vacuum pump on the other end. Hope the experience helps. That's what I did.

Thank you DDR. It's a B2200. I've been driving it since the occurrence for short distances and it runs fine. So, hopefully the fuel pump is alright. I changed the fuel filter before I started working on the truck. It had been sitting over a decade. The tank was all the way full of fuel when it was parked. I drained the tank and filled it with fresh fuel and some fuel cleaner. I changed the fuel filter after about 250 miles and it was pretty dirty. When it started stalling on me I replaced the fuel filter again but the fuel in the filter was like new clean. But I couldn't prime the filter. The primer pump worked but no fuel came out of the purge port. I wonder about the pickup because I blew into the fuel line at the fuel filter under the hood and could hear bubbling in the tank. After blowing out the line it primed and ran. So, I was wondering if the pickup tube has a sock or roll over valve on it. Or maybe it just picked up enough trash to stop up the tube or fuel line hose. I'll drop the tank when I get back from vacation but the curiosity is killing me. I work on machines for a living so it's in my blood. Can't help it. I found a radiator shop nearby that restores old tanks so they are there if I need them. But I was hoping since the tank was full when it was parked it would have preserved it somewhat. By the way, my dad had filled it with heating/farm fuel. The red dyed kind. I think he was storing it in case of some emergency. I'll post more when I get inside. Thanks again.

I got the tank off. Full of rust. The pickup tube is just a piece of steel tubing that goes to the bottom of the tank and makes a 90 degree bend at the bottom. The return tube from the engine is the same. The drain plug sits up from the bottom of the tank about an inch and is higher than the pick up tube. Clean fuel from the frain plus and about a half inch of rust (looks like brown sand) in the bottom of the tank. It's going to a radiator shop nearby that refinished fuel tanks. Thanks for the help, Rob
