Hi,

id like to know if we use higher flowing fuel motor pumps will increase our fuel consumption?

Say, will a Sard 280lph be having the same fc as the 265 or 235 lph Sard or even the 255 lph walbro?

If it does not, then it will be great to be in a current NA car and have the potential to save it for future turbo plans...

 

Fuel still has to go through a fuel regulator so in theory no... BUT if your fuel pump is bad and you are not getting the correct amount of fuel now (running lean) then yes you will use more fuel. With this being said I doubt your running lean and it should use the same amount. I just purchased the Automotive pump for ours. should be in later this week and it's just an easy do it yourself swap.

 

My pump has went bonkers... Thus the FC... It's Walbro... So there u go..

what automotive pump is that?

Denso>?


I have been recommended this though... DeatschWerks 300+lph...


Not surez if it will sit in the 04-08 fuel pump assembly...

Jeff of Mazda Maniac mentions the DeatschWerks will destroy the fuel regulator of the OEM... In that case, will the Sard do that as well?

 

aeromotive is another brand, check them out. my friend has one in his trans am, said it was really reliable and does the job, his car is a built 11 sec trans am, N/A.

 

Having the part number and link to the direct fit; drop in pump for the rx-8 would be greatz
