Which cars use the Bosch 044 pumps? |
you can put the fuel filter in a number of places. i put mine a massive marine one before the bosch 910 such that all fuel from the tank gets filtered before it sees any pump. i trusted that the lines and pumps and rail etc was clear of debris. there is a little screen on the 044 inside that would catch larger stuff.
another reason that i did it like that is that that filter of mine is not designed to run under pressure. i couldnt find an oem one with large enough orifices to satisfy my fussy self. you could however parallel 2 or more new stock filters to get the flow needed for big power.
the damper on the rail is a small acumulator of sorts i'm thinking that running dry might be better than a half arsed supply of fuel from a rubberised diaphram. but i could be wrong.
half of the point of it is to run out very suddenly and all at once. there is enough fuel to supply my engine as it stands at 350hp + for a full minute in my surge tank. in that time, the other pump should have scavenged the last of the dregs from the bottom of the main tank and slowly topped it up till there was none left to scavenge.
as for the 044 ;-) WRC cars use it :-) its a motorsports pump. i dont think any road cars came with one, but i could be wrong. the 910 came in some mercs. there is a porcshe pump thats similarly rated to the 910.
