Gas Tank Line Seals, Seals for the two hardlines out of tank Options

[SteveL]

Hey all,

I have been fighting an engine dying issue for a while, and am at the step of replacing the fuel sock in the tank and cleaning the tank.
I have the tank drained and removed. The tank is awesome. The sock might have had enough crap on it to cause the issue, we'll see.
Anyway - 2 lines on bottom of tank, supply with sock and return. I ordered the sock a while back (I think from 914Rubber?) and it came with a copper washer the same as the larger one in the pic. The return line also had a gasket, but it is a fiber washer, not copper. Looking for that gasket, I saw on the AA site that they have a large and small fuel tank seal listed, so I ordered a set thinking it would have me covered.
So, the smaller copper washer from AA appears to be the right size for both lines. But if that is the case, why did the sock come the larger washer?
Which is right for each? I want to be damn sure this is right, as reinstalling and filling the tank is a crappy way to find out it leaks.



Thanks!

I am in the middle of changing all of my rubber fuel lines as last time I did this I somehow used inferior fuel lines that does not hold up with the current gasoline formulations. I have SS lines down the tunnel and will be using R30 9 rubber lines for the rest. I plan on using Permatex Permashield Gasket Dressing on every connection in the fuel system. I am not going to do this job again and plan on not having too for a very long time. I have used this product before and it is awesome and works great. The fuel system will probably not leak anyway but using this product will be my fail safe. I am using fabric washers. Good luck to you and to me as well.
All the best,

Where did you get the fabric washers?

At my FLAPS....I actually had to do some drilling to get it just right. Copper sounds good but I am just going with the fabric. Seeing gasoline puddles really isn't very much fun so I am hoping the new rubber and the sealant do the trick.
