In tank fuel pump.

[482supersnake]

I have been restoring a 61 f100 that has had the 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 fuel tank from a 1989 Bronco at the rear of the frame. It has a stock replacement in tank fuel pump, 3/8 steel fuel line front to back with an inline fuel filter. Tried to start the truck today and it wants to fire but there is very little fuel volume or presure. Pulled the supply line of and turned the pump 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

Sounds like a bad pump to me.  The line is clear and all that?  I assume that the Bronco came with EFI and had a high pressure pump in the tank.

I was just doing some more research and it looks like some of the EFI Broncos had 2 fuel pumps. The one in the tank is low pressure and they also had an external high pressure pump. Lines are all clear so I might have to get a different pump.

Sounds like a pump problem, even if it was a low pressure scavenging pump, it should have some volume.

I'd get a good in tank pump maybe one for a 90s Mustang and if you need to adapt it to the current pickup so be it.  Assuming you are running a factory regulator, or a regulator of some sort?

Get a gallon of low odor mineral spirits or turpentine  (both have a high flash point) rig the pump, dunk it pump in a bucket outdoors and try it again. Clean old paint brushes later! Do not try this with gasoline.

Your research is correct. There was a lift pump in the tank and a high pressure pump on the frame rail below thw drivers door.

I have an extra late model Mustang style pump I am going to try and make work this weekend. Thanks Scott

I was able to get the other fuel pump into the tank and the engine runs great now. It 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. Scott

Maybe, but how's the coolant level?
