Big gas leak on Thanksgiving morning, very thankful

there's a big long thread on this not so far back.

 

TLDS-

There's no 'right' way, but lots of options.

use 5/16" hardline for most of it.

You can still buy the OEM flexible plastic fuel line that's self-sealing if exposed to excessive heat (the thread Toby is referring to).  It'll work just fine and is a lot easier to route than metal line.  And it won't be near 50 years old, either, like yours was.  

 

As conscientious as BMW was (and presumably still is, in these litigious days) they wouldn't have routed plastic fuel line through the passenger compartment if it was even slightly dangerous.  That yours  broke right by the firewall indicates that the end that exposure to both light and engine compartment heat probably degraded the plastic--and/or the weight of the rubber fuel line and filter put an additional load on it...

 

I know for a fact--and from experience--that it will seal itself if exposed to heat--like from a torch--and that it's very long lived in its meanderings through the passenger compartment, where it's cool and dark.  It's all original on both my 69 and 73. 

 

Just a suggestion to consider.

But, we are still waiting for the answer to Jimk's question.  The plastic line was meant to be used with the mechanical pump pulling fuel through it, as opposed to putting an electric pump in the trunk and pushing fuel through. 

 

A leak in the original configuration will suck air into the line and allow fuel to drain back to the tank when the engine is shut off.  A leak in that line with a pusher-pump will cause a Big gas leak.

    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
