Cleaning a Hydrostatic fuel gauge
When using Hydrochloric acid to clean a Hydrostatic fuel gauge how long can the acid safely be in the gauge with ot causing any damage to the gauge ?

I’ve found that a thin wire like a guitar string works well for cleaning the passages in them.

Re: Cleaning a Hydrostatic fuel gauge
I have just cleaned the glass tube and bits on the 34 gauge today, I used a cotton bud with half of the cotton peeled off and brake clean.

Re: Cleaning a Hydrostatic fuel gauge
When using hydrochloric acid to clear the line I do a rinse with acetone or laquer thinner several times and low pressure compressed air to blow it all out. If the line does not clear with the acid in a few min then it is really plugged.The wire will work only to the 90degree bend at the base of the glass tube. I have had a few that were plugged solid so had to cut the line about an inch from the brass hex and then with the wire to roto root the line.I then use a bit larger piece of the copper line and slip it over then soldered to reconnect.
Renners Corner sells a new sight glass tube with the copper line.The line needs to be soldered on to the hex. Here are pics of one I had to splice Last edited by deuce lover; 04-21-2024 at 02:12 AM. |

I just leave the acid in for about 10-20 Minutes. Then rinse over and over again with water, or follow the instructions above. If the acid can not reach the stoppage chances are it will not work.

Re: Cleaning a Hydrostatic fuel gauge
Thanks for all the tips, I did a 15 min acid soak some old gauge fluid worked up into the glass tube. Did a couple of water flushes and blew it out with air.
Then a isopropyl alcohol and a pipe cleaner in the glass tube then more compressed air to clear it out. Now reinstall it and see how it works. Mike |

Re: Cleaning a Hydrostatic fuel gauge
When installation is complete you need to drive the car to get it to function .
