I've replaced the fuel pump, bypassed the front tank switch and running on the rear tank, but after I drive for a short while, less than a block or two it feels like I'm running out of gas. I removed the front tank (Long story) I wasn't getting ANYthing through the line(s) except air, but today for the first time in over a month I got fuel to the fuel pump after forcing compressed air into the rear tank to get fuel in the lines. Now I get a few blocks and it runs out of fuel again and it won't draw it in. Originally I thought a blocked inlet in the tank, but both tanks?
Any ideas?
Thanks... If I have to reword this let me know.. It's tricky I know..

I also changed the fuel filter, fuel pump and drawing from rear tank. the bypass of the switch under the frame that changes tanks is a length of hose bypassing the switch entirely. Is there also a secondary pump inside the rear tank? I doubt it, but hey, I could have miossed something.

I can run it in park and rev it up all day long (figurativly speaking) and it won't stall, but I put it in gear and drive and it dies. I can't afford another tow. (I use my truck to make my living and I'm totally broke now) Last time I got around the block to the alleyway almost to my driveway and it died. I got it running long enough to back it in and out of the alleyway. The fuel pump is fine I think. I wonder if the carb is at fault now, but the lines went dry everytime it has stalled before. The front tank had half a tank (about 8 gallons) and the rear was empty (originally) I put 3-4 gallons in the rear tank and getting the same results. I have a hard time thinking its the pump because it's brand new and the old pump works ok too now I find out :( That was wasted money I think. No leaks in the lines and no apparent kinks or pinches in any lines. I'm flat out lost on this one. I've fixed cars for years and NEVER run into this.
Thanks again..

Well, I am running into the same problems regardless of which tank I use. Though the front tank has been removed, when it was in place everything was doing exactly the same thing. I can get so far then everything dies. When I had it towed I couldn't get it started to save my life, but now that it sits in the drive for a month it fires right up, but dies a block later. I've replaced all the rubber from either tank up to the fuel pump and both tanks have an anti siphon coil on the inlet like a spring to keep people from putting a hose in to steal gas. How could a baggie get in there if I can't get a small hose in? (tried that too)
Something else is going on, but I just can';t figure it out :(

Oh yeah, I checked for vapor lock. That was the first thing I checked. I have both gas caps in the cab so that's out. I am going to check to see if I'm sucking air... then what? Any other ideas? I need help here folks.
Thanks again.

Oh......here's a thought......fuel tank vapor lock.
try loosening the gas cap, just to see.......
Or, you're sucking air.
Get a two liter bottle, and a length of hose (fuel hose) long enough to reach the bottom of the bottle.
Disconnect the supply hose to the carb\TBI, and run the long hose from the fuel supply line and down into the bottom of the bottle
Turn the key on, and let the bottle fill up enough to cover the bottom of the hose and look for bubbles.
(you should not see any) and it should fill up quickly.

well here is what i ran into years ago with one giving me the same problem, the rubber fuel lines were bad. over the years the fuel had caused the rubber on the inside of the lines to deteriorate and it got like a flap inside the line when the fuel system was under pressure it pulled that loose piece of rubber up so it acted like a door closing off the fuel supply. also here is something else you may want to look at but it is going to involve dropping the tank again. maybe you have made someone mad and they put a couple of sandwich bags in the fuel tank for you.

You might need to put a bigger or a stronger fuel pump. it sounds like your fuel pump is to weak . it can't suck enough fuel to keep the lines and the car full of fuel.

Did you replace the fuel filter? Sounds like an obstruction in the fuel system.

you more than likley have a hole in the line before the pump. so the pump is sucking air instead of fuel from the tank

what about the fuel filter - have you changed it (those) out?
I had an engine that was starving for fuel - and $1.97 bought me a new engine- vrrrmmmmmmmmmmmm!
