I'm trying to get my '88 22RE 4Runner back up and running and recently replaced (and relocated) the fuel filter. Previous posters had relocated the filter to the fender so I thought I would do that since it is very hard to reach on the engine block. I installed the copper washers that came with the new filter and tightened the 17mm bolts as much as I could. I jumped the fuel pump to test the fittings and had gas spraying all over the intake manifold from the fitting on the engine side of the filter. If anyone has ideas on how to seal these fittings please let me know. - Thanks New fuel filter location. Connection to right spraying gas on intake manifold!
Judging by pic i dont think the engine side hose will reach to fit in the cradle in the new spot. Maybe with it turning as you tighten its not crushing the crush washer sufficiently?
I would get new crush washer and return to original location even tho its a PITA to get to so it fits in the cradle then tighten again
OEM washers are aluminum, not copper. Copper will probably work, but they're designed for much higher pressure systems, like brakes.
"Spraying" fuel sounds like more than a crush washer issue. I'm going to guess that if you could look closely enough you'll find that the banjo fitting is not quite lying flat on the washer. That fact that it isn't in the cradle (as 87-4runner points) by itself shouldn't matter, but the rest of the end of the fuel filter probably has something tilting the fitting.
Isn't it on backwards? The fuel line coming from the tank bolts to the front of the filter, and the line going to the fuel rail/puilse dampner mounts to the rear. Which means the directional arrow on the filter should be pointing at the firewall. Or did you change how the lines run, too? I can't tell by the picture

Easy to get backwards because of the way it is plumbed.
Thanks everyone. I followed the fuel lines and the arrow on the filter does point in the direction of fuel flow from tank to engine. I did find the original washer still on the bolt on the side leaking and fixed that, duh. I tried rotating the filter so the engine side line ran through the bracket but that made no difference,as I still had a leak. The leak is a very fine mist coming from where the washer and fuel line meet. Everything else looks good. A friend suggested a locktite gasoline compatible sealant on the bolt but judging from the design and where the leak is I do no believe that would help. Thanks for the video, unfortunately I have an A/C unit so extra lines to work around. I think if I managed to get the filter in the original location it would still leak and I'd have less chance of fixing it in the original location. I ordered a new filter and will try new washers. Any thought on trying to rotate the engine side line so the fuel line mounts to the filter on the opposite side? I assumed the fuel line bracket be the same on both sides so which side mates to the fuel filter does not matter. But maybe I am wrong.
