Preloading also helps line up the diaphragm with the bolt holes. |
There's no reason not to have all the bolts installed, but not tightened all the way, before preloading. |
I agree and slightly preloading the diaphragm allows the bolts to line up so much easier. _________________ Contact me at [email protected]

This^ looks like it was made from something else (that's how professional it looks if completely-from-scratch homemade).
What is it made from, if not completely homemade? _________________ “If you care for a thing long enough, it takes on a life of its own, doesn't it? Mending old things, preserving them, looking after them – on some level there's no rational grounds for it.”

Just wanted to share my jig I made from some plastic I had laying around. It already had a hole centered in it so I just played off that. Set a pin in the middle at 13mm and tapped two 8x1.25mm studs in it.
Clamps nicely in my hobby vice. |

^^ That's slick
I have an original jig and find I don't use it. I prefer my bench vise. I put a punch in it 13MM above, push the body down to pull the diaphragm into position and tighten the 6 screws. Much faster. _________________ Contact me at [email protected]

Yeah, I usually put them together without a jig... getting ready to build a few and came across this thread. I thought I’d whip one up with what I had laying around and try it out. I took apart one pump and it’s missing a small reed/check valve and the small retainer plate/screw... so I gotta find those pieces before I can play. |

If you need the reed valve and retainer, PM me. I have tons and can drop one in the mail. _________________ Contact me at [email protected]

I just rebuilt an original pierburg fuel pump for my 1967 bug. Thanks to all for the info on the preload requirement and jig. I found it easy to assemble the fuel pump, leaving the upper housing screws loose enough allow the diaphragm to move. After setting the preload on the bench jig, which will pull the diaphragm into the lower housing, you can tighten the screws. |

Just to add to this thread for a 36hp pump at tdc the plunger is at the correct 35mm hieght so no tool needed. Also it put my ww diaphram at a relaxed fit so easy top install with it on the motor. It will be awhile before i can run it on my new build but anxious to see where my fuel pressure falls. |
