Large Bosch Fuel Pump Flow Rate ?
 

Bosch part# 0 580 254 942

Anyone know the rate of this pump.

David,
I took a Bosch 0 580 464 042 out of my S2. (Could you have read the number wrong? They are hard to see.) It flowed 750cc in 30s when i tested it, which is spec for the late pumps. Earlier ones pushed 850cc/30s. Late pumps have a green band around the body.

Nope, correct number, it is sold by Lindsey Racing and was recommended to them by Motec, but they did not know the flow rates.

The pump is a good bit larger than stock unit, but still bolts right up with some shoe horning on the inlet hose.

It is silver with a blue plastic band around it.

Is stock unit on some 12 cylinder cars, so flow shoud be alot just wondering how much.

I'm aware this is super old, but most specs I find on this are 225-250LPH. Its a step below the 044.

Back from the dead...
I found this while I was poking around for similar info.
I don't guaranty its accuracy, but it sure looks official.

FYI, I have a used Bosch -044 pump with all the fittings for all 944/968/951. The pump setup was purchased from Lindsey is in good working condition and was used in my track only car for 3 years or ~2000 miles.

Asking $135+shipping.

Thanks for the info guys 👍 What I can say is that pump has worked fine for the past 17 years @ 340 rwhp. I purchased an 044 from Lart some years back but not found the need to install, probably will some day. :burnout:
