    So in the midst of my S/C install I thought I'd put a new fuel filter on as well to help with fuel delivery. And after I installed the filter and started up the truck it was leaking like a MF'er at the rear connection of the filter. So I removed it to put the old one back on for comparison and it slightly leaked from the front side connection. I then put the new one back on again this time connecting the rear connection first and now it's leaking the same way just out the front side now! (frustrating [​IMG]) I tried disconnecting/reconnnecting like a zillion times and can't get the shit to stop.

    Has anyone else had this issue? And can give me some tips on how to keep it from leaking?

    I thought of this whole project this would be the simplest task and it's turning out to be the only thing holding me back. Any help is appreciated

    I'm trying to think if thread tape would work or not.


    If all else fails..nothing holds like a cross-thread.:D

    NO!!

    Gas eats just about anything. Teflon included. And fuel fittings are not designed to seal at the threads. The threads are only there to create pressure on the sealing surfaces. That may be a flare fitting or a banjo fitting with copper washers.

    Please don't use teflon. That has fire written all over it!

    From reading Alpha's earlier experience, I'd recommend you unbolt the filter from it's bracket while trying to line up the threads on the fittings. Always harder to line things up and keep from cross threading if the filter is already bolted down.

    I deleted my earlier post, looks like no copper washers on a first gen Tacoma filter.

    I changed my fuel filter on my first gen a few months ago. It would not stop leaking as well. The day I did it it was about 15 degrees out and the gas on my hands was cold as hell. I put a bucket under it and came back at it the next day. They are flare fittings. I cleaned the ends of the in and out tubes (connected to the truck) and tried again. Getting the rear on wasn't so bad but then the front was a bitch. I finally got them both started before torquing them down. I used an open end wrench on the filter and a flare nut wrench on the fitting and tightened them until they bottomed out. They finally sealed. I thought it was going to be a simple operation in the beginning but it really was quite an ordeal.

    Thanks. I had actually just come across your thread a couple min ago through google. Looks like I'll try to disconnect it from the bracket first then tighten the shit out of that front fitting. I'm hesitant of disconnecting if alltogether since I have the back fitting nicely secured.

    I can tell by just eyeballing it that it seems like the front fitting needs to still go in slightly more compared to the rear. Hopefully I can get that shit all tightened up in the morning. I gave up on it for the day. Been wrenching since 8AM :eek:

    Thanks for the quick input everyone.

    The newer Tacoma don't have fuel filter, it's call a fuel sock in it's in the f&@":;g gas tank. Another bone head move by Toyota

    I just wanted to post a follow up to help out anyone that may have this same issue in the future.

    I got the leak fixed this morning!!! :D:D
    I took out that 10mil bolt that holds the filter in the bracket and kept the cab mount bolts loose as well so the filter could sort of hang freely. Then I just loosed the front filter connection and tightened it up a couple of times and it was ALL GOOD :cool:

    Thanks again for all the help.
