Fuel pumps?

Fuel pumps?
Hi, I'm new here. I have an '85 cabriolet that has 2 pumps, and the in tank one is bad. I just bought the car cheap, and found no fuel at the injection distributor, and found very old fuel in the tank, the second pump operates with 12volts applied, and the fuel really reeks and the pump seems slow.
Does anyone know the specs on the in tank pump?
I mean is it only to lift the fuel out of the tank?
Does it produce much pressure, or is the "transfer pump" producing the pressure???
Thanks, Earl

ORIGINAL: Jrailer
its not a very high pressure pump
they will sometimes run with it not working
they are cheap $80.00 if you lookaftermarket

Hi all, I'm John and new as well. I just bought an 81 Cabriolet yesterday.
It's been sitting since 2000, b/c no fuel pressure. I haven't gotten it home yet but the
guy I bought it from said he replaced the pump in the tank, and it didn't work. That's why
he gave up. He has the rear seat up and you can see the top of the tank, so I believe
him.
The car was impeccably taken care of otherwise, with 110K. for 750. I really don't mind spending
too much on it, to get it up and running. I love this body style, and have always wanted one.
Anyway, my question is; If he did replace thetank pump, where should I look next for a problem? He also said that there are two pumps? Relay? bad connection?
I'll know more when I get it home on Saturday, but you know how toys are...
thanks, John

RE: Fuel pumps?
John,
It could be electrical? Get a Bently manual, and check for voltage at the pump first. the pressure pump is on the passenger side right next to the tank, get to it from below.
Check for voltage there also, perhaps the wrong pump was replaced? There is a fuel pump relay on the fuse panel.
If it's been sitting for that long, and had any gas in it, the tank will probably need to be cleaned out!
Good luck, Earl

RE: Fuel pumps?
Yeah, I got a Bentley manual with the car. My first planis to remove the old gas. Then I'll do as you say and check voltage at the pump. You said I should check the voltage from below the car? I thought it was in through the top? Course I haven't had enough time with it yet, so I'm probably wrong. The guy has the relay sitting on the dash, I should just go ahead and buy a new one before I start...
Where is the other pump located?
sorry about all the questions, but I appreciate the help, Earl.
