Guys, anybody know about pumps for the C230k?

Sad, really that I have to ask but thanks to a lot of misinformation by sellers offering universal pumps with darn all info and on top of all this prices vary wildly. Even some will state their Bosch pump is correct for the car and others will say the opposite about the same pump, I think most of them just look up some cross reference book or other and go from there.

Now, I have the several part numbers to start off with.

Merc (Bosch) original A0004705994 which supersedes to A0004707894. €/$ ??? (get a bank loan)
Bosch 0986580372. €140/$180
Pierburg 722156500. €180/$230
Delphi FE0346. €120/$155
Welbro GCL602 €108/$139

All of the above are right for the job but too expensive except the Welbro until shipping charges & taxes are added. There are 'non name' pumps available from less than €50/$64 but I've my reservations about buying any of those. In actual fact I wouldn't use any of them.

The spec from what I understand is: 4Bar & 110LPH. Also the outlet has a 90 degree angle. Now, this outlet (as most pumps are straight outlets) seems to be a problem and thus limits my choice of pumps and makes it more pricey.

So, I've two questions:

1. I presume I don't require the 90 degree outlet, just use a longer bit of hose from pump to filter or use a shorter hose with a 90 degree bend. I suppose I could fit a banjo kit too.
2. Can anybody advise on using a reasonably priced pump i.e none of the one's listed above.

Thanks in adavance
