Hi to all,

I have a problem with Bosch 040 pump.
Setup:
Sr20det, ecu EMU, 370ccm, t28 ball bearing.

I replaced fuel pump (previous died) for Bosch 040. I put full tank and drive maybe 200miles and it start to whine like previous one. Right now I got 3/4 of fuel. After 10 minutes of driving whining becomes louder and car goes up to 3000rpm, after another 5 minutes 2000rpm is not possible so going from second to third gear is a dream. But when I let it rest for 5 min or so it starts to work propperly, but after 5 minutes whining and no power starts again.

Any ideas what is wrong? What to check?
