Fuel Pump

[MJTru]

Hi guys I have 3 new bosch fuel pumps on them has these numbers

9 580 234 005 I cant seem to find any info on them in detail even after googling it.

I notice on it that it has 24v on it but from memory if im correct thats the max voltage for the pump. So it can still work at 12v or 14 for that matter.

Im planning on setting up my fuel system using these pump if they can work for my r32 gtr. Looking to support 800hp max for drag racing.

Thanks any help is appreciated.

That is the pump in question

There are some near perfect Chinese copies getting about these days, are you sure they are Bosch? Did you buy them from a reputable seller?

I think you are better off with a decent single pump off the surge tank, gear driven if you don't mind the noise. Have you looked at Weldon, Fuelab etc?

Well its stamped bosch on the pump mate. I did get them from a reputable supplier. And they were expensive. I have always wanted to go take a look at fuelab. But having these for a while and there brand new never used I wanted to know if they will work. The box the pumps came in are yellow with bosch stamps all over the box. they came from Germany not that it cant be faked from germany. Lol. Ill tell you how I got them

One of my friends work for TREX that makes container handlers called straddle carriers. On the straddle they use these pumps to lift fuel up 60f to the top machine platform where there is a small tank the supply the big diesel engine. I know it works at 24v and for diesel. Can they work for gas. Anf at 12 to 14 volts. Any specs avalible for them.??

Considering there is nothing from Bosch in a Google search, and all the hits come back as Alibaba, including one link selling the straddle carrier including said pumps direct from China... I have my doubts.

Even if they were genuine, running twin pumps without some way to tell if one is faulty is putting way too much faith in the pump, no matter where it's made.

If it works at 24 volts I doubt it will work at 12 volts

If it works at 24 volts I doubt it will work at 12 volts

Looking at bosch pumps on line. Some I notice are variable votage. 24volts being the highest. Hmmm

Ok if its 24 volts why cant I use a 12vdc to 25vdc converter. ???

Pumps sound dodgy but if you want to use them dummy them up with a battery and a couple of petrol cans and measure the output (flow) and pressure before you start installing them in a car.

Another thing to fail.

Don't cheap out on a pump for a big power build.

I wouldnt. Leaning your engineout and costing a fortune to replace/repair isnt cheaper then spending $200-$400 on a decent pump now is it?

I know you probably don't want to spend more money, but in the long term its better to have a pump that you can rely on.
