Big clogging in fuel filters:

a) on the core support next to the radiator. Turn it upside down in a glass jar and very carefully blow air the opposite direction of the flow... what comes out... black junk? could be rubber fuel line degrading and creating sediment. orange junk? rust in the tank most likely.

B) In the fuel tank. Take the fuel pickup out of the tank in the trunk (has two hoses attached) and look at the screen/filter on the bottom of the pickup. Clean that thoroughly, look down in the tank and check for varnish and rust floating around.

Those are the two places that most likely have enough crud inducing power to stall your engine. My car had the same problem early on. It had both rust in the tank and bad, degrading 25+ year old rubber fuel lines.

Those two things are the low hanging fruit of trouble. You can also upgrade to a later model 318is fuel filter to replace your TII one which has about 3x the amount of filtering material. That saved me for a while...

Good luck!

designed to hold the 60 PSI or so your pump puts out (can you say engine fire?) and the filter element will disentegrate and plug things up.

Ask me how I know....The filter at the end of the pickup will become clogged and then unclog itself when the car is turned off. If you own a Tii and intend to keep it cleaning out the tank is a Really good idea......

my car just got over similar problem- the gummed pick-up burnt out the first new pump, which uses the fuel as coolant. luckily my mechanic has a good relationship with his parts supplier, who accepted his warranty claim.

lesson learned, spent the $85 to have the tank professionally cleaned. well worth it.

    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
