914World.com _ 914World Garage _ Fuel tank "nipple" seals

Posted by: matthepcat Aug 21 2015, 09:59 PM

Hello world.

I recently restored a fuel tank and am in the process of assembling all the new seals and parts.

I have a new copper filter "sock" plus the paper seal that comes with it.

I also have two copper seals for the large and small tubes.

How are these supposed to go together?

Are the copper seals for the tank side or the nut side?

Is the paper seal just an alternative to the copper seal on the larger tube?

Thanks for the help,

Matt

EDITED

Large diameter nipple is the feed , small one is the return.

Install the the copper washer on feed nipple, then the sock, then insert into fuel tank, then tighten the nut.

Return nipple, install copper washer, insert into tank, then tighten the nut.

Not sure about the paper washer ... never used one. Maybe the paper washer goes on the sock before inserting into the tank. Does the id of the paper washer fit around the sock?

Where did you obtain the washer kit?

WAIT !!! I don't know what I was thinking

I edited the previous post to correct my mistake.

The copper washers need to seat up against the end of the threaded bungs, so they need to be installed on the nipples prior to inserting into the tank. The nut tightens up against the nipple flanges, but the washers actually do the sealing.

Sorry, Matt
