    1968 plymouth roadrunner

    I'm not the expert! I thought all trim on these cars was originally stainless. My 68 does not have trim on the wheel wells. I have had to replace some trim and now, I've only found it in chrome. You can tell the difference.

    You'll love this. As stated before, SU out of the tank float in full position, gauge read full and dropped to empty when float was moved to 3/4. In the tank, filled up with gas the gauge reads 3/8 of a tank. When I came to a stop, the gauge would move up to 3/4 then slowly move back to 3/8 after...

    Thanks for hanging with me on this. The sending Unit is such a simple item I don't see how they could ever go bad except if teh wire or striker broke. I have checked the resistance on the last three units and they read pretty much the same on Ohms. When I ground the wire at the tank the gauge...

    I did not get a new gauge. I've tested it the way the manual says to and from the battery ground to connection under the kick plate and the gauge appears to work. that is, it goes up to full then drops back down when released. Could the gauge read the SU but not correctly? I hate to throw more...

    Got the newest sending unit and RTE Limiter. Testing out of the car w/jumper wire from sending unit wire to where wire hooks up to SU and ground from battery to SU. and new limiter installed, The gauge would not move, bent the float full stop out of the way, bent the float arm and gauge would...

    I ordered the RTE limiter this morning. I adjusted the float past the stop and got this gauge to show full. Of course by now I've beat the s--- out of this sending unit and am ordering a new one. Again. And my wife does not like walking either!

    Reading more of the articles for a RTE limiter and For $50, It seems like a no brainer. Also looked up the cost for the old ones and the price seemed to range from $43-$78. However I already have two that are working. I had thought when a voltage limiter went out things just stopped working...

    At the gauge, the two sending units floats were set at full for the readings above and dropped to below E when lowered. I had no idea there was a alternative in voltage limiters. I briefed through the advertisement above and will spend more time looking into it. It certainly sounds like the way...

    A little progress. I now have two SU on hand. Hooked up the old one (third one) out of the tank, checked the ohms 75.5-9.1 And it made the gauge move to the empty position, put the new one on, (fourth one) and the gauge moved to 1/4 full. As Russ has said as well as Carl, sounds like I've been...

    Measured it this morning. 5volts, jumping between just above 4 and just below 6.

    I have tested the SU in and out of the tank, moved the float and nothing. I don't really understand the getting voltage to the SU when it's a ground return. I understand that all positive have to have a negative return to work but when I first started working on this issue the fact that from the...

    Yes, there is fuel in the tank.

    Do you mean run a 12 volt lead to the positive side of meter and ground of meter to the wire from the tank? I know, rookie question, just don't want to make any more backward steps.

    I have not ordered the ground bar shown above Got the new sending unt (4th one) Hooked it up and nothing. Ran a ground wire from the battery to the fuel line on the SU and nothing. Ran a ground from the battery to where the wire hooks up to SU and shows hte gauge is working and it also showed...

    I have a ground from the battery to the engine, battery to body, engine to body, fuel tank to frame. As a uni body I would expect the body would ground the frame? I have also ran a temporary ground from the battery to the sending unit. Upon removing this sending unit I noticed one of the tabs...

    Thank you, I will look them up.

    I have a 68 roadrunner with the original gauge cluster. In the past, the automatic trans was switched out with a 4 speed w/overdrive from an early to mid 80's Dodge truck or HD Van transmission. I cannot find a speedometer cable with the push-on end w/quick release holder and a 7/8" screw-on for...

    Russ, Thanks for all your replies, you've answered a lot of questions over the years, don't give up on me. i don't know quite what you mean by "fuel line ground strap", most of my fuel line is rubber. I have added a ground from the tank to the frame and have ran a ground from the battery to...
