92_rugby_subie Posted October 7, 2010 Share Posted October 7, 2010 So I replaced the rear fuel filter today... The new one and the one that came off were different, but still fit... The previous one came off right side up (hose lines on top) but because of the spacing of the new fuel filter, it would only fit upside down... am I risking anything like this? Pics below... This is the nasty fuel filter I took off. Heres the replacement one, hooked up to the proper lines, and in place (upside down) QUESTION AGAIN: Since the fuel filter only fit upside down, am I harming anything by having it this way, or should I try and fit it right side up?

idosubaru Posted October 7, 2010 Share Posted October 7, 2010 sounds strange that it would only go that way and i didn't look at the pictures, but it shouldn't matter at all. modern FI systems are under high pressure (relatively speaking) so orientation of the filter isn't going to make a difference if that's really all that's going on.

92_rugby_subie Posted October 7, 2010 Author Share Posted October 7, 2010 Oops, I should say that this is a 1984 DL Sedan.. Hopefully it doesnt affect it, Thank you Grossgary for your quick reply.

idosubaru Posted October 7, 2010 Share Posted October 7, 2010 whoops, vehicle helps. i just assumed the 92 in your user name was in reference to this vehicle. someone else will chime in since this is carbed right? so it's carbed - those are low pressure like 8psi or something, but i doubt it matters, i actually looked at the pic's this time. it has to go against gravity either way, just a matter of whether it's the feed side or pick up side...flipping it only alternates those i'd think.

92_rugby_subie Posted October 7, 2010 Author Share Posted October 7, 2010 So I need to reverse the lines? Or just find a way to flip it back over? I had gas dribbling down my arms so I was trying to get it in without twisting the lines, and thats how it popped in.. Quote Link to comment Share on other sites More sharing options...
92_rugby_subie Posted October 7, 2010 Author Share Posted October 7, 2010 Any more ideas? I dont wanna ruin something... Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 7, 2010 Share Posted October 7, 2010 (edited) And what makes you think there's a right-side-up to a sealed cartridge filter? It's designed to be installed exactly as you have done (as long as you followed the arrows on the filter for inlet and outlet). In other words it doesn't matter in the slightest. EA carb fuel pressure is 1.5 to 2.5 psi. GD Edited October 7, 2010 by GeneralDisorder Quote Link to comment Share on other sites More sharing options...
92_rugby_subie Posted October 7, 2010 Author Share Posted October 7, 2010 Whew. Thank you Rick I followed the arrows, I undid one hose, and put my thumb on it, looked at the filter, it didnt have an arrow, so I put that hose on the new filter with no arrow, and then did the other one, glad I did it right... Score one for me:banana: Quote Link to comment Share on other sites More sharing options...
Flowmastered87GL Posted October 7, 2010 Share Posted October 7, 2010 You may want to climb under there and follow the fuel lines just to check that the one with the out arrow does indeed lead up to the engine since you mentioned the old filter not having an arrow. Or did you mean it did not have an arrow on the first side you undid?? When I used to change my fuel filter on my GL I used a set of vise grips wrapped 5-7 times with electrical tape. Let me pinch off the line but not damage it (only make it tight enough to stop flow, not crush the hose) Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 7, 2010 Share Posted October 7, 2010 Needle nose vice grips are invaluable for pinching off lines. You can pinch the line between two quarters if you don't want to mess with soft-grips or tape, etc. GD Quote Link to comment Share on other sites More sharing options...
92_rugby_subie Posted October 7, 2010 Author Share Posted October 7, 2010 I shoulda done that Cuz now my arm still smells like gas several handwashes and 3 showers later Oh well, it has been done, but I will look and make sure that it goes to the engine. I took the hoses off one at a time. Took one hose off, noted which side it came off of, and put it on that, the arrow hose went where it belonged, where the other didnt. lol Quote Link to comment Share on other sites More sharing options...
