Evo 8 fuel filler neck fix

Hi guys I know this has been a common problem for some here on the board and I wanted to post my fix for this discountiued part. First off this was not an easy fix without the use of a lift there was a lot of curse words along the way😆. Of course this filler neck was leaking above the subframe giving no access so the subframe need to come out. 20 yr bolts do not like to come out 😆. Well after a lot of cursing and having to drill out 2 of the eight bolts it was out. I tell you it wasn’t pretty under there here’s some pics





with the filler neck out I had to figure out how I was going to fix this ugly looking filler hose. Knowing what I know now I’m pretty sure the leak is probably happening in the same area on most of these hoses. Here’s the filler neck out and my fix:



the last pick is what the whole neck looked like after a lot of wire brushing. So as you can see I cut the elbow out and replaced it with a fuel hose elbow from Amazon TKKEUEP Gasoline Fuel Filler Neck... https://www.amazon.com/dp/B09ZKZDWT5?ref=ppx_pop_mob_ap_share
which worked perfectly. I’m going to finish this post in 2 parts to avoid doing this a third time by posting to many images

the only missing piece was the coupler to connect the filler hose to the lower rubber hose that goes to the tank. Thankyou Amazon YSIL 1-1/2 Inch Hose Barb Coupler... https://www.amazon.com/dp/B0BXD8VYW1?ref=ppx_pop_mob_ap_share
here’s some pics of the finished product installed








Well with that done it was time to clean everything up under there and make it look nice. I cleaned the subframe and control arms and sprayed them with clear and polished the exhaust




well with all that done and new bolts for the six bolts I needed to drill out here’s the final result. Not perfect but nice

it sure was gratifying to go to the gas station and not have the attendant freak out with a puddle of gas under the car. Well I hope this can help a fellow Evo owner in desperate need of fixing his leaky filler hose.

Thankyou guru. The car has not seen water ( except to wash it)or winter since I bought it in 2018. Garage kept so it should be fine for as long as I have it.
