What is the best way to remove the fuel pump from the tank of an 82 crossfire? Can it be done without dropping the tank?

 

I believe '82s are like the C4s that you CAN remove it without dropping the tank.

 

yes, you can remove the fuel sending unit without dropping the tank.

Remove the gas lid, the rubber bib and undo the fuel lines (disconnect battery!) and remove the fuel pump/fuel sender connector.

Then undo all the flange bolts and carefully lift up the sending unit, rotate it a bit to the left and right to find the position where it comes out and you can pull the entire thing out.

If you swap the pump, get a 85 or later TPI pump. It's a direct fit for the sending unit but you will need to cut the stock wires and install new wires for the connector on the pump, it's different. The wires come with the new pump (delco!!). Use soldering and shring sleeves around it. Also make sure you use a new strainer or the warranty will be void. Another thing to use it the rubber pump sleeve to minimize noise. Another smart thing to do is to use hose clamps on the little hose section that conencts the pump the the up tube. Do not overtighten, the outlet on the pump is plastic.

Before someone will chime in and say the TPI pump gives too much pressure, pumps create flow not pressure. Pressure is created when flow meets a restriction, in this case the pressure regulator. The pressure will still be what the stock setting is set at, because with more flow the diaphragm will just open more and route more fuel to the return line. The only way the pressure would rise is if the flow overpowers the diaphragm and when full open the flow is so much that the regulator is restrictive enough to raise the pressire. The other way would be if the return line would be restrictive. This is not the case, it will work without any problems and it will be much more reliable and able to keep up the flow needed for full pressure at WOT.

 

Hey, the TPI pump will give to much pressure....wait...never mind...:lol:


Welcome to the Corvette Forum crossfireman.... :seeya

 

:iagree: but I say get rid of the little rubber line between the pump and sending unit. Go to a junkyard and get the part used on the later cars. Most any GM car or truck with an in-tank pump mid 80-s and later should have it. Instead of a hose that gets soft and moves around it is a plastic and metal part with o-ringed holes on both sides.

 

Thank you very much. I will have to try that. So, the TPI pump will fit in the tank ok? I have heard bad things about 82 pumps and to replace them with the TPI pumps.

 

There is a "how to" thread on the crossfire forum, but it's down tonight, or I would post a link to it for you....
Maybe tomorrow. :thumbs:
