While going through the engine after purchasing my 1965 bug I decided to replace all the fuel lines with new. As I was trying to pull the old line off the fuel pump outlet, the brass fitting came out. A search of the site here led me to clean up both the brass fitting and fuel pump and replace the fitting using red Loctite. After reading all the topics on safety wire, I decided to also safety wire the fuel pump outlet to the pump. I could find no photos on how to do it so here is what I did. Hopefully, this will be useful to someone else out there. Rest assured the other end of that line is also safety wired to the carb.

In addition to Locktite, you can roll the pipe ends between two coarse files to dimple it and give it a little extra grip.

I've posted this, my 1600cc engine; safety wires on both inlet and outlet.

For my other engine, which does not have retaining clips on the fuel pump horizontal pivot rod, I made and installed brackets to makes ure it stays that way !

I applaud your quest for safety, but it looks like the loop attached to the body of the pump could slip off rather easily?

Also, while you're at it, will you be putting a safety wire on your carb inlet pipe?

Nope, it's under the lip, so in a "channel" or valley.

I already did that too.

In the mid-1970s, on this same 1970 VW, I was driving home one day, smelled gasoline, assumed it was from a different car (I don't have a sensitive nose). About 5 miles later, I was home, stopped the engine, and the factory crimp clamp on the factory hose had come loose from the fuel pump (this same one, by the way), and was pumping liquid gas (1) all over the engine and distributor and (2) some got to the carb so I had no driveability issues.

I thought the whole VW was gong to explode in flames, I just let all evaporate, then fixed it with a traditional hose clamp, and safety wire (mid 1970s !!!). On mine, the brass tubing was NOT loose and did not come out, this was the flexible braided hose coming loose in normal driving, even with the factory crimp clamp.
