Need input!! Fuel issue, again.

Ok, so. If anyone remembers, My car has weird starvation issues. Like an eating disorder, but different. Related more to liquid fuel.

(The following takes place between 4 and 6, with 3/4 tank of gas or more)

Today, V drove wonderfully (on the new RBs/Sdrives I might add, silky smooth) until I turned up a long steep incline.. About 200 yards into it, the car began to buck and sputter.

Fortunately, I hit a flat spot in the road and it grabbed enough to get me over the to of the hill. SHEW!

About 20 minutes later, I'm dropping down on to I275 E from Montgomery road. The ramp is down and banks to the right, a good one to dig into. So it did, and about 5 seconds into the WOT it bucked and gasped again! I milked it back to smooth idle before I had to merge into rush hour traffic and away we went.

I stopped at the next station and topped off the tank at this point.

But on the way to score some seats, I hit another long steep incline and she did it again. I barely made it up..

Next, I stop to get some parts on flat ground. The car sits for about an hour and I offer to let this new found friend take a drive while I sit shotgun. As we go to pull away, she bucks and stalls. And that was that.

As before, the clear filter before the pump was dry. No gas making it to the pump.

But check it, after sitting for an hour while we swapped in e21 seats, we looked up and miraculously the filter was full with gas again!!

We pulled the sender and cleaned the screen and body with brake cleaner. --indeed there was rusty gas and cleaner flowing from it.

Tried to pull what looks to be a drain plug on the tank, but it wasn't budging so we reassembled the sender. After a bit of cranking, she started up like a champ and idled fine for 10 minutes or so. But with air bubbles that would't stop coming fromthe line into the filter.. Checked all lines that were tampered with (one) and all was tight.

-so I loaded the newly acquired e21 391LSD and stub axles into the trunk and rolled off. Made the right turn, punched it (I had to) and guess what? buckety buck, coughity cough. STALLLLLLL.

After pushing it back 100 yards or so to the driveway from whence it came, I pulled the fuel line off of the carb and had my man Adam crank it. NOTHING.

I BLEW BACK THROUGH THE LINES UNTIL THE TANK GURGLED. CRANKED IT. NOTHING.

We are trying the pump tomorrow, even though mine looks relatively new. All I have is a mechanical from a 1600. I hope this works...I signed up for my first autoX on sunday.

-sorry for the long tale, I wanted to paint an accurate picture.

Any and all advice is needed, welcome, and appreciated.

Sorry about that. You probably aren't eager to take it in to a shop. However, if you change your mind, try Foreign Car Svc. in the Huber Hts. section of greater Dayton. Mike McCarthy is your man there. I've had great luck w/mine since 2003, largely due to his efforts. (& a little luck)

don't give up on the tenk drain screw -

it's got to be done - drain - swizzle some clean gas, and

drain again - this is #1 - use a correct size socket this time and

give it a sharp RAP!

new fuel pump - NOT used pumps! what's the matter with you !!

replace the rubber hoses at the gas tank sender

remove the carb top and clean the float bowl -

and make sure you have a squirt from the accel. pump

when the bowel is full and back together - probably

need a new accel pump diaphram from the sounds of

the krap fuel going through the system

I hear you on the new pump. And I will indeed buy a new one.. they're just a bit scarce in these parts, and i just want to get her home. Hopefully my day old RB's didn't get ganked over night.

The tank drain plug takes an allen head. I will try again when I get back to the house. Or maybe when I get up there since its been sitting over night...better idea.

UPDATE.

Put the 1600 pump to the test on Sunday at an autoX, it didn't like that. Its leaking like mad.

Couldn't find a rebuild for the stock pump so I just ordered a new one

from Rockauto. 52 bucks vs. BMW's 170.00?!

I checked all of the lines. They are recently replaced. But now, since I pulled the sender, a constant row of air bubbles is being pulled into the filter. should I be concerned??

I think my sender is off as well.

We'll see..?

    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
