what u pay for that and did u hook it up to washer fluid or somthing cuz i dunno why you have a pic of itjimb said:My newest mod.
STI Auto Switch
STI Nozzles (in the STI RA Spec S Splitter/Hoodscoop).
TAAP 3-900 pump
My own circuitry to trigger the pump (555/relay at 10% duty cycle).
Fuel pumps deliver volume and pressure. Sprayer is only volume. To give you some idea, my pump is only 3" tall by 1" in diameter and is the same one our washer nozzles use. A fuel pump might actually burn up because it's not pushing on anything. It might free spin too much and over heat. A fuel pump is WAY OVERKILL anyway. Now if you wanted to spray your whole car, it would be a good way to go.pace said:Hmm... I have my OE fuel pump lying around. Any thoughts on how well it would function in an IC spray application?
Very nice switch install! I assume those are from the STi..
As you can see, he only runs his sprayer at 10% duty cycle. So your fuel pump at 33% would still be enough to wash the car after rallying.pace said:On a more serious note, the fuel pumps can run at various duty cycles. I could rig it up to run at 33%, but it may still be too powerful for this application as you say.
haha just had to laugh at that onepace said:So you're saying that bigger is not necessarily better? Hmm...
Well, whatever. I can assure you that my 'pump' as you call it, is significantly larger than 3" long and 1" in diameter.
