Which Fuel pump for S50 in E30?

[Z2TT]

Hi Guys.

I've gotten mixed opinions on this, some say the stock E30 pump works fine, but others say it does not produce enough pressure as S50 needs 5 Bars.

I have seen a guide on putting a E36 M3 pump into a E30 housing/bracket but it seems to be quite some work, maybe the guide im reading makes it look harder than it is. Has anybody done this?

Is there any quiet pumps out on the market that produce correct pressure and are an easy swap over to the factory E30 housing?

Thanks
