Noisy Fuel Pump[ALL/1998] posted by Owen Woodland on
Sunday, 10 August 1997, at 8:23 p.m.
Although I have asked about this already:
I have a 1976 244 (dl), b21E fuel injected engine with
The world's noisiest fuel pump!
The pump doesn't sound all that loud externally, but when it resonates up through the trunk and into the car, it sounds very loud. I have confirmed that it was in fact the main fuel pump making the noise, by unplugging it (and thus rather amusingly killing the engine, but the noise did stop). It will cost A$140 (US$100 or so) to replace, but the mechanic assures me that it PROBABLY won't give me any trouble.
Question:
Is it a case of bearings running a little dry or something? If so, can it be lubricated with any degree of ease?
Also, when cold it is often very much louder just as you are warming up the engine. In addition, when driving (in the cold, most noticably), and you stop at lights, the noise goes to an almost unbearable level (I suppose that this would be when the fuel pressure backs up because it's not using as much), putting the car in neutral and revving the engine drops the noise back to bearable again.
Any ideas, anyone?
Thank you very much,
Owen in Australia.

I replaced the rubber sleeve around the main fuel pump in my old 82-245 and also put some of that stcky black gum tape, like used on AC stuff, between the lines and the firewall and this helped kill the noise resonation thru the fuel lines. I used a piece of spongy but non porous rubber sheeting about 1/8th inch thick betweeen the pump and the circle bracket that holds it on. Also check where the fuel lines connect/pass thru supporting brackets/line holders for play and use gum tape here as well.
Of course it could just be age, we all get bit noisy when we get old.It is a 76! How old is that in human years-does Volvo age translate like dog years?

Yes, well I like a quiet car, and after having been in my friend's
'82 244 (GL) which is as quiet as a sitting room on wheels (apart from
a sound which is reminiscent of a tin can going through a combine harvester,
only quieter, which I seem to hear in all 2.3 litre volvo engines), and there
is no substitute. Besides which, it just gets on my nerves having a never
ending droning sound coming from the back of the car.
Thank you very much for the advice, and I'll let you know how it goes.

Oh yeah, and as to the Volvo years question, I'd guess that my car ages
around about 3:1. In the mid-sixties, when most people have retired,
the old 244 is still plugging away, and although it's no spring chicken,
it can still go when it has to. Ha ha.
Besides which, I hold a great respect for the pre 1978 volvos, which still
have the old solid metal, shock absorbed bumpers, and pay no heed to the
fuel economy. Damn the prices, and 5000 revs ahead. Ha ha (maniacal laughter).
Which is not to say that I would turn up my nose to a more recent 2-series,
but hey we take what we can get.

Owen, Here in States we had the killer bumpers until 1982, my old 82-245 was what I called an "Urban Assault Vehicle" and would go toe to toe with any NY City taxicab (Ford Crown Victoria/Chevy Caprice and the rare Checker Marathon only 4 left now used to be 5,000). I always won! And I took pictures of my victims!
As to engine noise, obviously you never drove a Saab 96 with the 2 cycle 3 clyinder engine-Ringa Ding Ding Ding all day long-60mph max down hill with the wind!
