I had a bit of a look, but you’d need to check the pump physically matches as I don’t know much about Subaru parts and just following part numbers.   I’m guessing this is old style abs with ecu and sensors attached to the pump?   Anyway this may help…     27531AC000 has revision 010,020,030 then 03a then 040 and at 27531AC04A it jumps over to superseded 27539AC04A for 1999-2001 2.2L 2.5l legacy and forester  there’s a 050,060 and ends with 27539AC06A   last model on amayama https://www.amayama.com/en/part/subaru/27531ac040   from there it seems to go to the forester code with 27539FC010 seeming to be the most common number for 1999-2002 with some places selling it as 1997-2003.  that has revisions 020,030,040      Only model on amayama https://www.amayama.com/en/part/subaru/27539fc010  

Hi Team.    I'm on the hunt for an old ABS Pump as mine is leaking at the join.    it is a old legacy style with the part number 27531AC000.    if anyone is able to shed any light, that would be greatly appreciated    thanks a million. 

Headliner out, no need to remove seat belt. On the b pillar set the seat belt height to half way. undo the top bolt under the little panel. Slide up 15mm or so the you pull the bottom outwards over the white round trim push clips and slide it down until seatbelt won’t let it go further.   Will be installing this tomorrow, after testing it this week. https://www.aliexpress.com/item/1005007251604620.html   Ok firstly it’s not 2cm thick, it’s 1cm after a few days sitting unrolled. There is no way it’ll ever get to 2cm. So between 2mm and 10mm overall. The backing was clear plastic not pictured paper. After backing removed it does stretch well so will conform to curves nicely. The glue on the back seems strong enough. If you stick it on the rubber foam rips apart before the glue let’s go. Could be a task to remove or clean up in the future. Though it is closed cell and doesn’t absorb water. It has a slight fireworks or match head smell to it. When set on fire with lighter it self extinguishes so that’s good.   Needs 2 rolls to do the roof. Since it will be above airbags roof between front and rear heavy beams it 1550mm and 1200mm wide.   Also have speaker fill that is 30mm thick to cover the whole back of the headliner to replace the single 30mm thick woollen block of100x400mm. This will be be 960mm wide as to not go down the side and cover the curtain airbag path. It’s also well away from the pyrotechnics which are in the c pillars so should be fine. I will test burn some to see what it does and if it’s bad then may run some 50mm wide alloy tape along the sides.   Will test fit with fill and if it’s does bulge anywhere then it’s headliner out again and glue the fill in place.   All this is due to the car being black and roof get over 80c measured outside. So as soon answer the AC is off the heat starts to come through the headliner. Could also vinyl wrap the roof the same black so the vinyl insulates the metal.   Glued some metal u screw to the fender vents where the mud flaps have been screwed into. There is a random assortment or screws from previous owner. One front is short self tappers. The other is so long it screwed through the inner metal of the guard.  

Almost removed headliner so can install bumpy foam and layer of speaker stuffing to block heat and reduce cabin drone. Plus broke a clip on back of one of the roof handles. Just need to remove one front seat belt to get the thing out tomorrow.     Fitted adjustable flasher relay and set to a reasonable speed. removing the old unit for the clip was the hardest part. Even after unclipping the relay stack from the main fuse box. Have a fixed rate one arriving next week as well.   Removed the fender vent panels and got some rust primer to seal edges the larger cutouts needed to get more airflow. https://www.iwsti.com/threads/fender-rear-engine-vent-optimizing-performance.191959/

I had thought about that but didn’t like the idea much.   The risk of a clutch system leak drain brake fluid doesn’t sound good. I’ve had clutch slave cylinder fail as well as a pinhole in a clutch line before.   Plus using motul 660 as clutch fluid seems excessive.
