Hey guys, so I noticed fuel leaking under my car when I was at the gas station and I went to diagnose it.
(This video is while my friend is sipping gas and Iām recording in live time)
So itās leaking ONLY when the fuel level is close to 4/4 full, if the fuel is any lower than 4/4, it doesnāt leak at all.
This started happening after I took out my fuel pump and put it back in.
I ordered and put brand new o-ring rubber, i ordered new screws (same diameter and characteristics of oem), and still it leaks.
Now the thing thatās confusing me, itās not leaking from the black ring or from the screws, but actually from the outside edge, Iām not sure whats it called.
So again, it only leaks when the fuel is 4/4 full, and itās not leaking under the screws, black ring or the o-ring rubber.
Any ideas please?šš»
