Having fueling issues with my '87 Crx Si, and need to drop the tank. Would like to replace the in-tank fuel filter/sock while I have it out, especially since I believe it is clogged, and potentially the cause of my issues. I believe the part number is 17517-SA7-931, but every site I've checked didn't have it and said it was discontinued. Anyone know where to get an aftermarket one, or even know of a universal filter that will work? It appears to have the same part number as Integras, Accords and Preludes of this year range as well.

 

If you still have the stock pump then I'd just replace everything while you have the tank down. That fuel pump is just about 33 years old now.

Walbro 255 is the common option, personally I like Skunk2's 255 as it's a bit quieter and has yet to give me any issues.

 

I tried replacing the pump already (stock only works intermittently), ended up with 2 brand new bad Delphi ones from RockAuto. Going to order a Walbro in the next day or so. Stock pump is an external one, so I don't have to drop the tank to replace it, just the sock filter. Still can't find a new in-tank filter for sale anywhere though.
