I have been restoring a 61 f100 that has had the Front suspension from a 2004 Crown Vic installed and the drive train from a 2000 Crown Vic installed. I removed the fuel tank from the cab and installed a new fuel tank from a 1989 Bronco at the rear of the frame rails. It has a stock replacement in tank fuel pump, 3/8 steel fuel line front to back with an inline fuel filter. I tried to start the truck today and it wants to fire but there is very little fuel volume or pressure. Pulled the supply line off and turned the pump on and it was just a trickle of fuel coming out. Tank has about five gallons of fuel in it and the pump seems to spin fine just not building up any pressure. Am I missing something here or did I just get a bad pump? Scott

How far off the bottom is the pump? Id say you just got unlucky.
Try removing the filter and see what happens as well. -
The fuel test was done without the filter. The pump looks like it is in the correct position from the bottom of the tank.Comment

Migjt check fuel flow at the sending unit, if still a trickle it would have to be a bad pump or internal tank issue. If good flow and volume a restriction in a line.Comment

After some research I found that the late 80’s early 90’s Broncos have two fuel pumps. A low pressure pump in the tank and a high pressure one on the frame. I swapped out the in-tank pump for a high pressure mustang unit and the motor run fine now. The motor came out of a 2000 crow vic. police car that was wrecked with 24,000 miles on it. The motor has been sitting since 2002. Fired the motor without the cats and it ran fine, let it get up to temp and the fan came on, no problems. Hooked up the full exhaust and started the truck and let it idle for about 2 min. and thick white smoke is coming out the tail pipes. Could something have gotten into the cats? Like I said the engine runs smooth and has great throttle response. ScottComment
