I am about to buy a Walbro fuel pump and was wondering how badly it will affect my gas mileage. Also which one should I get, the 190 ltr/ hr. or the 255?
Thnx for any info

 

IM also wondering the same, although i got a FD fuel pump. Just wondering about the gas milege as well if i rewired the fuel pump

 

I've got the 255 and I just got 21 on a spirited back road jaunt the other day. Some "spirited" anyway. It doesn't seem to have had any effect on my fuel consumption.

I'm pulling out 3% at idle but that's it, w/the safc.

 

I get bad mpg in the city... rewired 255.

Mostly because its running rich at idle, i need an S-AFC.

Highway i think i could do 25+ mpg at 110-120km/h

 

get the 255. the 190 is around stock...

your millage will drop a little bit
