Should I consider?
« on: September 14, 2023, 05:43:48 AM »
Should I consider replacing the fuel pump on my '85 K100RT as part of my refurbishment project, given that it sat for three years? I've already purchased the 12/24k maintenance kit from beemerboneyard, which includes a new fuel filter along with other items. If the fuel pumps are known for their reliability, I might skip replacing it. I've been soaking the tank in white vinegar for the past week, and the pump's mounting bolts have significant rust buildup. The plastic clip also appears quite yellow, and I'm worried it might break if I remove it unnecessarily.

Not if it's working now.
Once I had a Collie pup. Dug a hole and covered him up. Now I sit there by the hour. Waiting for a Collie-flower.

+ another 1
+1 You're already considering it. You should stop now.  :laughing4-giggles:

Consider instead removing the pump holder assembly entirely to inspect the pump's pre-filter—it's a basket or sock attached to the bottom—to determine if it is ripped. If the yellowing holder breaks upon removal, it's better that happens now than as a surprise event. There are still replacements made for the holders and the circular rubber vibration dampers within them. Disconnect the battery negative cable from the transmission, remove the fuel cap assembly, remove the pump's wires, squeeze the tabs on each side of the holder and lift out the whole business. Pay attention to the orientation of everything.
