Well, I need a new sending unit for the 1987 Dodge Ram. How much am I looking at spending and how hard is it to change? I am fairly mechanical and have a friend that is very mechanical. Any tips or suggestions would be helful!

Whoops, sorry I typed that post too fast. I need a new sending unit for the gas tank. It sits right up on top of it, so I know I'll have to drop the tank. It is for a 318 gasser.

depending on how rusty everything is and if you have access to a lift, it may be easier to remove the bed bolts and raise the bed up, we do that alot at my shop when all the stalls are full. just drag an air hose into the parking lot for the 1/2 impact and go to town. good luck :weightlifter:

If your dropping the tank, the less gas in it the better. Remember that gas sloshes, so if the tank starts to tip, all the gas will run to the lowest side, and get very heavy on that side very fast. If you can, get a buddy to help, also try to use two transmission jacks if you have access, and strap the tank to them to help keep the tank from getting goofy. Also spray the heck out of the bolts on the sending unit with good penetrating lube, and let it sit, as they are probably good and rusted, it is quite a pain if one of them breaks off.

Good advise. I have a 12V pump to get all the gas out. I had just filled it up. There is about 23 gallon or so in there. This is probably a cause to the stalling out I have been having recently, right?

on chevys, removing the bed is the way its mostly done. lift it up and move it back.

fuel sending unit will not cause your truck to stall. fuel pump may but they uasally work or they dont.

I think I might have an issue with the sending unit and a cracked fuel line that is sucking in air. Everything is a little rusty back there and it is time for things to be replaced.

I did my Chevy. It has everything inside the tank. If I ever have to do it again, I will definately explore the "remove the bed" option. Geez, I really did not enjoy that job. $650 just for the pump/sending unit/filter. Lines to and from the EFI unit and vent were extra. :cry:


When you do it, do everything when you're in there. It's worth a couple extra bucks not to have to do it again anytime soon. As an extra, I also redid my brake lines because they ran nearby along the frame rail. It was only a matter of time before they went due to heavy rust.

The breaklines were done recently, so I don't have to worry about them yet, but might as well just do them while im in there.

one thing about chevys - when replacing the sender/pump assembly, replace the electrical connector too as it frequently melts and kills the new pump by causing excessive resistance.

Still working on this truck. I have dropped the tank, disconnected the fuel lines, and bought a new sending unit (that was fun to find). I can not get the ring around the top of the sending that attatches it to the tank off. I think one of the tabs is broken. I can't get that thing out for the life of me. Anyone have any tips or tricks?

soak it down with a good penetrating oil.. I like PB Blaster. get a good BRASS punch and hammer.... ease it off, counter clockwise til it unlocks. If it wont budge... new tank and ring.

Or you could find a way to drill, cut, bang, beat the old lock ring off and out. But I wont go there,,, that one is on you! A new ring should be at yur dealer of NAPA

On those rings you have to get the tabs up and then smack the hell out of them with a punch counterclockwise as stated above. If it dont come off then head to the junkyard.

Thanks xcopterdoc.

lawnmaniac883: The tabs have to come up? I have been trying to push them in. They go up? I might be on to something here lol! I am so far over my head on this one!

Hahaha... he works on a house going up down the road from me. He has changed 10 of them, but he still can't get it off. Might just be time for a new tank. By the time a break the ring and have to locate another one I could have the tank back on the truck and running!

I think the trucxk would blow up! Nice thought!

Yes, there should be 3 tabs that need to be pryed up and then you smack the hell out of it and unless it is rusted on there real good, it will break free and spin off.

Well, I'll give it a try this morning seeing that I am all caught up on my work. I have been trying to work on this thing for months! I'll see what I can get done today.

I am just about ready to bolt everything back together tomorrow when I get a few hours. My last question (for now) is which is the postive end and which is the negative end on the sending unit itself. I have forgotten which is which and would prefer not to blow it up.

Don't worry, it will be here before you know it! I didn't even get a chance yesterday because I couldn't get the filler neck into the tank and it was past 1 in the morning, so I'll get back at it later today.

Belive it or not, I finally got it running today. It only took like 35 hours, but the thing is up and running. It runs like crap, but I can work on that. I am just happy that it runs. I have worked on it from Friday night off and on until an hour ago. Only broke one wrench and three sockets. I have spent $110.86 so far when the local shop quoted me at around $1450 to do all the work and have it towed there. I love saving money!!! Next thing is to get it running right and then start working on the race car!

I actually never got really frustrated with it. I was only pissed when Dodge sent my the wrong sending unit and I had to modify it. Also, that little ring that goes around the top is discontinued. There was one in the whole USA and it was $95, so I made my own. It was running like crap all day yesterday. Today it wouldn't run without sputtering. I took the 2 month old battery back to Sears and it turned out to be junk. I got a new one for free and the truck runs great. Still having some troubles with the stereo tho. It only gets AM and no FM stations.:cry:
