Do you have any data on how much noise reduction is attributable to the pads in front? I have a nopisy electric fuel pump I'm trying to quiet down

 


The material will reduce the panel noise transfer and aide in noise reduction. I do not have a specific dB reduction specification. Density at 3/8” is 4.0-5.0 per lb. 

 

By the ear test there is a good amount of reduction, or softening of the transfer of sound. 
 

Hope this helps.

Have been considering rubber mount between fuel pump bracket and engine compartment panel.

Haven't found quieter pump (Carter).

People who have pump in trunk says noise still there, just behind you now.

Have louder muffler.

Drive faster than I probably should.

Will go with pads next.

Using later E21 fuel pump underbody is $$ option.

Go back to original mechanical pump. Upgraded when went to 2bbl Weber as suggested. Not sure it needs 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
