Re: [Chevelle-list] fuel sending unit
I dropped my fuel tank and removed my sending unit. I put the red lead of my ohm meter on the post where the power wire attaches to the unit and and my black lead to the ground wire on the sending unit. I moved the float arm up and down and my ohm meter hardley moved at all. however when it was hooked up and in the car my fuel guage was reading from full to empty. 5 gallons of gas would send the guage to full. It looks like I need another sending unit. Has anyone been able to get a sending at their local auto parts store or am I going to have to order it from some where else.

If it goes to empty then it is an open circuit in the sending unit. The easiest way to bench test a gauge is with another sending unit, the sending unit is just a 90 ohm resistor. With the 12volts and ground applied to the gauge hook up a ground wire from the gauge ground to the body of the sending unit and the hook up the gauge wire from the gauge directly to the wire on the sending unit. When you move the float on the sending unit up the gauge should go to full and when it is down it should go to empty. You don't need to find the correct sending unit to do the test as almost all old GM sending units used the same 90 ohm resistance.

Re: [Chevelle-list] fuel sending unit
Just looked it up on Advance's and Autozone's sites and it's available, but you will probably have to order it. My past experience with both of them is usually they will have your item in a couple of days. Both places had the sending unit listed for a little over $50.00. About the going rate, I think I paid $55.00 and change for the one for my 69 4-5 year ago from Paddock. Sounds like you have found the problem. With the ohm meter hooked up and moving the float up and down the meter needle ( if you have analog meter ) should be jumping all over the place. Really the weakest link in the whole gas gauge system. Good luck.

Re: [Chevelle-list] fuel sending unit
I work at advance and if it's in the warehouse, we can get it overnight, if it's factory direct, it usually takes a couple days to a week with free shipping.

Re: [Chevelle-list] radiator
I sure would, then I would know exactially what I'm looking for. Thanks I have my original radiator and shroud out of the car. I installed a cross flow. Do you want pics? -Original Message- From: chevelle-list-boun...@chevelles.net [mailto:chevelle-list-boun...@chevelles.net] On Behalf Of Chum Nault Sent: Saturday, April 17, 2010 10:16 AM To: 'The Chevelle Mailing List' Subject: Re: [Chevelle-list] radiator I have a radiator problem that I hope someone has an answer for. I am restoring a 65 L79 with a manual transmission and no a/c. I got this car in pieces so I do not have the original radiator or fan shroud. I ordered a radiator #604644-1 and a fan shroud #605623 from Ecklers. The radiator I received is perfect except there is no flange on the engine side of it to bolt the fan shroud to. I can't find any pictures of a non A/C L79 so I don't know exactly how it correctly mounts. I called Ecklers and they confirmed that I have the correct radiator for this car and I can easily fabricate some brackets but I want to put this car together as correct as possible. Any suggestions?
