I think the threads on my 32-36 are M10 x 1.0

I now disagree with some of the timing advice I have given in the past.  I misinterpreted the distributor curves in the Blue Book. 

I've switched from using ported-vacuum to manifold, with better results. 

I apologize for spreading misinformation.  (3-28-2024)

I agree.

I don't think they are all the same.

Seems especially likely/possible when you consider that there are GenUine WeBers as well as KnOck Offs.

 

Here is the style that mine uses

My vintage* Bressol knock off uses a threaded connection that I am pretty sure is tapered but some have pressed in so I think Toby makes a good point. 

 

* I call it vintage because it dates back to before knockoffs were fashionable.

Ok so some small and unexpected progress. I received my VDO oil gauge, with "metric" adapters. I found one in the kit that screws into the Weber properly, that would give me a  1/8 -27 NPT out that I can use an adapter to get my -6 connected to.  I still have my order coming from Japan for my BST fitting, I wonder if the two are identical?.  I will check to see if there is any information on the adapters in the metric VDO sender kit.

Ok so I think we have it. 

 

"Metric kit. Includes VDO Ohm range sender (10-180 Ohms) 1/8-27NPT sender with M16, M14, M12 x 1.0, M10x1.0 & 1/8x28BSP adapters"

 

I bet it is a 1/8x28bsp.  I will check the other threads tomorrow.

Ok, so I have had a problem with the fuel pressure being too high in my car.  Likely for a while.  I put on a Holley regulator, but didn't work I changed out the Pierberg mechanical for a "Clackity Clackity" pump to see if there was a mechanical build up in the spring that would increase pressure, I changed out the Holley regulator for a Redline, no change. 

 

I put in the Jeep fuel filter, and it flowed too much for my crappy clackity clackity pump, so I had to reduce the return line by putting a hose clamp to it. 

 

So now it maintains about 3 PSI and drops to 0 once the car turns off. 

 

It still didn't fix the original problem, why/how does the pressure increase, from 3 lbs to 6-7, flooding my carb (a lot) after I turn off the car?.   It takes maybe 5-15 min to build to 6 PSI and then after the bowl fills up it fills up my primary. 

 

I took off the check valve I had installed by the tank (not needed) and no difference. My gas tank vent appears to be fine. The little hose goes directly outside.  

 

 

Mintgrun here are the answers to your questions. 

 

1) have you removed the gas cap to make sure there is no pressure in the tank?

that little vent line could be plugged, or something.  

 

I have, but I can't recall if it was before or after I took out the check valve I will check again 

 

a PO put a screw in mine and I was pressurizing my tank via the return line until I figured it out and removed that screw.

 

2) What do you mean by clackity clack pump? 

 

The one listed below, I wanted to figure out if it was my Pierberg screwing up, apparently, it wasn't. A cheap little low-pressure pump.  I have a Carter rotary that I will install with the AN line setup.

3) Are you talking electric or mechanical?

Electrical pump for now. 

 

4) You had to restrict the return line on the jeep filter?  Yes 

5) You did use the center nipple to feed the carb, right? Yes

6) The one off to the side for the return...?Yes

 

7 Which model filter did you buy? A FRAM G3583

 

I'm not sure why you are starting a new thread when you have a fairly long one on this topic, full of potentially useful information for people trying to help you.  Why spread it out like this?  Sorry again

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
