Identify Fuel Tank Sender


Recommended Posts

 I just purchased 1969 bmw 2002/1600 last friday. I am in the process of fixing a bunch little stuff.


My fuel sender is bad. ( i tested the fuel gauge with a POT, and the sender with a volt meter). At least I think the fuel gauge is good. If I jump it, the gauge reads full. If set the POT to around 15/20 ohms it reads around

7/8th full.


I am getting help from another fuel problem here. http://www.bmw2002faq.com/topic/148685-hard-to-fill-gas-in-the-tank/


From that thread it sounds like I might not have the right tank for my year car.  So, what I would like to know is what year do I need to order to replace this part here?

test it with an ohm meter first.   right side up (empty) should be zero ohms.  upside down (full) should be about 80-90 ohms.


someone is selling one in the parts for sale section now.  if that one is gone, i think i have a spare.  you will need a new o-ring seal for it and there is a white plastic tube that fits over the outlet on the pickup that is required.  not present in your pic.


suggestion though...search is a very useful function on this forum and should be your first choice for help.  a search on fuel sender would net you a lot of information on these.

haha. I already did search. I guess I will always have to include that I searched first.


I want to know what part to order. I see tons of threads on how to test fuel send, gas gauge. I don't see one with a picture of every year

fuel sender was made for which car.


From my other thread that I linked in post #1, post #14 http://www.bmw2002faq.com/topic/148685-hard-to-fill-gas-in-the-tank/#entry960232 You said "basically you have the wrong tank in your car." Which to me sounds like I can't just order a fuel sender for a 1969 bmw 2002. I was hopping somebody here could identify my fuel sender and tell what year I need to buy.


I did test the fuel sender it is bad. "( i tested the fuel gauge with a POT, and the sender with a volt meter)". I guess I should have added I set the voltmeter to ohm. I checked it at empty, full and It try move it someplace in the middle.


Thanks for your helpful information.

There are 2 possibilities. One sender is longer than the other. The tii had a deeper tank, and longer sender. If your sender reaches near the bottom of your tank, it is the right length. The short one will work in a tii tank, but won't pick up the last 1/3 tank of gas, so it will show empty and you will come to a stop, when there is still gas in the tank. The tii sender won't fit in the wrong tank.

    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
