Looking forward to the in car comparison :-) The 088 type equivalent I used was silent even with the failed in tank lift pump at 1/4 tank (745 Volvo).

@@makavelibenzze the fuel pressure regulator on the return line from the fuel distributor sets the fuel pressure. As long as the pump can meet or exceed the flow and pressure of the oem ones, it will work fine,

@@MMWA-DAVE woahh....okey means it does not damage the FD then it is fine enough...btway i messed the HEX key inside the FPR...i turned it all the way Off, i counted how many turns....and Open it back as counted but i messed it a bit turning counter clockwise/clockwise when finding an issue (misfiring, it was the cylinder head) what does the Hole HEX do? return back the fuel?

@MMWA-DAVE hit up an Australian company called "turbosmart" the dealer here set me up with a new pump and their fuel filter; it is working great. I did this after buying 4 bosch pumps in 30 months. Also if you are going to let these cars sit: add some Amsoil fuel conditioner to the tank and keep the fuel tank full (less air in the tank=better)

Are the modern racing pumps without seals? Or do they have better quality seals, because of the variety of chemical nasties in various racing fuels?

they are still not ethanol rated- the ones im looking at anyway. But hopefully are better than the bosch ones. They certainly seem better built but wont know till i try them.

Are you using Ethanol fuel?

its not sold in my state but absolutely would not be surprised if i ended up with some of that crap from the questionable place i bought fuel from once only.

@@MMWA-DAVE just got these now and the interesting part is the following in every mercedes document it showed but not specifically to m104.980 (jus t m104) the following 0 580 254 950 now the difference is the part no with 911 is (95l/h with 4 bar pressure) and the part no.950(120l/h 5 bar pressure) could this be the reson for fast wear of the pumps and maybe a slow acceleration of the engine ?
