MEP-803A Pegs fuel gage all the way down past empty.

I like the idea of using a spacer ring at the bottom to prevent it from touching the sides. I want to use the longer one so I'll have to make something similar so it doesn't hang up. Or I need to find one without the external float like the one the AMMPS uses as shown in post 5. Thank you for the help!

That is 5.5 inches. Six is pushing it the way the top sags.
Google around for best deal.

Are there any differences between the 802 and the 803 fuel tanks? Will the 5.5 inch work on an 803?

Yes, tanks are different. Read posts 20 and 21.
You need an 8" for a 803 but you may need to put a little "spacer" on the bottom to prevent the float from touching the step in the tank.

I removed the strainer basket because it was corroding. I open the fuel cap and look inside. Problem solved.

No picture.... what did you find inside??

for the 803 instead of getting the 8" and making a spacer couldn't you get get a 7.5"? the link to the sending units list all different lengths. im having the same issue with my 803..

The spacer isn't to reduce the depth it is to prevent binding on the tank "step"you can see the step on the right hand side of the photo

Is the spacer so the float cannot go to the bottom of the rod?
I need to replace a couple of mine. As well.

The spacer is to prevent the float from binding on the step as it goes up and down with the fuel level

Wow, what a great picture and what a clean tank!
Now everyone can see exactly what the ledge looks like and why you need a spacer on an 803!
Nice job.

I have used 3 or 4 of the 8.5" senders on the 803's. The float is very close to rubbing on the side of the step down portion of the tank, so I made a plastic ring slightly larger than the float diameter to press onto the very bottom of the rod to prevent the float from touching the side of the tank.
If you use the 5.5" you won't have any interference issues, but your gage reading will be off by probably 1/4 tank.
The SAE bolt pattern is such that you put the wires pointing to the right ( oil filter side of machine ) when looking at the tank to make the hole pattern line up.

Do you have a picture of this plastic ring or a item number of something that you use as the spacer

Unfortunately it was home made. I cut a ring out of 1/8" rigid plastic just slightly larger diameter than the float.
Then drilled the a hole in the center tight enough to press the disc onto the end of the sender, then a little JB weld quick epoxy to secure it to the sender.
Initially I was going to use a rubber disc, but was worried the diesel would deteriorate the rubber over time, so I went with plastic.
