Very helpfull, i bought now 220l/h fuel pump i think it will help. Change thos 495 springs into 410 high rpm springs and camplate into de143. i saw that pump rotate very softly , much more softly that on de110 and 495 springs. I set new KF value for 410 springs so maybe i must make them hughs and kisses more
hehe strange translate
It rotate like Td pumps does.
And what i saw in esitronic pump is that 11mm with de143 have one shim less under the plunger in roterhead. So maybe i must tightened those 410 springs much more. ( this shim have 1,0 or 1,6mm there are two of them , but 11mm have only one ).
hm maybe i buy second one 220l/h pump
