Just a quick note on anyone using the mechanical fuel pump on your stock motor or bigger motor be aware that I have found and seen where the fuel pump rod that holds the main pivot on the inside are found to work their way out either at the rear most of the time and causing your engine to start missing. I went and punch in two small marking on the front and rear of the pump where this small pin is the be set and preventing it to come out again. Just passing this along.
Thanks
Frenchy

Old news  This happens with the new reproductions pumps. Put the pin from an old pump in it with the two circlips on it. Problem solved. When i used the the mechanical pump and the pin fell out i stranded on the highway at midnight  |

And..... you really need to check the fuel pressure once you have rebuilt that stock pump. PSI could be as high as 10, if your pushrod length is too long... Amazing.

Happened to me on a trip to Vegas. That's why I found an NOS German pump.

If you lose the rod and you are on the road a quick fix is a phillips screwdriver to get home safely!

I know a lot of us are probably using an electric fuel pump so no worries but in case you are using the mechanical would not hurt to check it . As mentioned above you can replace it with the earlier style with the c clip.

Deano,
You are right about that. I had about 7psi with my rebuilt Pierberg and and close to the same with the Brosol. It took a bunch of stacked gaskets and some shaving of the rod to get it down to 3 pounds for the 42's. I had a little gas weeping on one of the assembly screws with the Pierberg so removed it and installed the Brosol as a interim. Checking what Frenchy's noted, mine is as he's described. (no cir clips) Going to re-install the Pierberg anyway.

I am going and start using an inline fuel pressure gauge to check all stock style fuel pumps and see what they put out to be sure they do not put out more than the 3psi.
