Rodolfo Lasparri Posted December 29, 2020 Share Posted December 29, 2020 Hello! I'm presently struggling with how to clean the fuel sending unit's screen, as seen in the picture it's pretty much fully clogged and nearly opaque in all locations. So far I've tried the dishwasher (shhhh) Carb and Brake Cleaner, POR 15 Degreaser and Solvent, Krud Kutter, Denatured Alcohol, and presently some mineral spirits. Several of which I let the screen soak for 24 hours, to date I've seen a very minimal change at best even using toothbrushes etc. Anyone have any other insight on what might actually break this stuff down? Thanks! Quote Link to comment Share on other sites More sharing options...
kiva667 Posted December 30, 2020 Share Posted December 30, 2020 Why not just get another one? If I was in North America right now I’d put one in an envelope and send it to you for free. I have several . But I’m here in the Caribbean till April. Still there must be lots of them lying around! Otherwise a soak in a mix of Vinegar and Coke overnight should work. 1 Quote Link to comment Share on other sites More sharing options...
R.I.P.B.M.W. Posted December 30, 2020 Share Posted December 30, 2020 One would have thought that all the methods you used would have cleaned it. The screen is designed to filter out small debris (sand, rust, etc.) and should be used in conjunction with a small inline filter after it. The screen color probably won't change back to its original color. Shine a bright light behind it and if you can see the light all around, it should be good to go. The back light will also reveal if any pieces are still stuck in it. A gentle spray of compressed air from the back side could also help.

2002#3 Posted December 30, 2020 Share Posted December 30, 2020 Yep, designed to hold back the big pieces. Mine looks the same. Clean as above and blow air through. Likely will stay black. Should be able to see through it. Back in and go. Quote Link to comment Share on other sites More sharing options...
Rodolfo Lasparri Posted December 30, 2020 Author Share Posted December 30, 2020 Thanks everyone, the mineral spirits are finally having some effect so far. I’m going to let it sit in them until late tomorrow and will try some light compressed air once complete and report back. Appreciate the input.

Mike Self Posted December 30, 2020 Share Posted December 30, 2020 I've found that carb cleaner and an (old) toothbrush works wonders on those fine screens. Toothbrush bristles are soft enough and small enough to get down in the corrugations in the filter without damaging it. And...that filter is very fine and looks opaque even when new; the holes are very fine. Based on what you've done so far, it's probably pretty clean. Shine a bright light through it; if you can see some light, you're good to go. mike 2 Quote Link to comment Share on other sites More sharing options...
Steve570GT Posted January 11, 2021 Share Posted January 11, 2021 On that note, My sending unit (69 1600) has no screen at all. Ordered one from ECS tuning (pn 16121106983) The one I received is way too large, about 80mm across. Looks like it should be about 50mm. Anybody know if the screen is available and what the part number might be. Doesn't show the sending unit on reloem for some reason Quote Link to comment Share on other sites More sharing options...
Rodolfo Lasparri Posted January 11, 2021 Author Share Posted January 11, 2021 That's the screen for the Tii, I also couldn't find a new one prior when looking. You might give Paul at Maximillian a call or Ireland. They both sell new sending units that are remanufactured, maybe they have access to the actual parts only as well.

Shawn Piper Posted January 11, 2021 Share Posted January 11, 2021 Just because the plastic is stained doesn't mean its blocked. Plastic turns dark brown when in contact with gas. You might see this with carb floats. This example from a Solex carb started off being white. I rehabbed my fuel sender and had the screen zinc plated. The screen is as clean as it will possibly get and it looks like this Quote Link to comment Share on other sites More sharing options...
