Difference between the 255 and the 190 Walbro fuel pump
Hi guys,
Sorry to start a new thread for this but I need to ask if given the same price, would you get the 255 or the 190 Walbro fuel pump? I can get them both at the same price and will use it together with a Walbro FPR...
I am getting it shipped to me at USD169.99, any comments anyone? Thanks in advance!!

At 50psi of fuel you have enough flow to supply 350BHP with the 190, 480BHP with the 255.
If you are using an FMU, the 190HP provides better flow at higher PSI levels and the 255 drops off eailer.
40-50psi idle with the 255 may cause lumpy idle and rich AFRs.

hey guys, first post for me!
sorry if this has been covered, but im a little unclear on this and i've read through all the info i could find on here.
if i get a 190 hp walbro, do i also need to get an afpr, or a peirburg..or any of those things? or can i just bolt in the walbro and leave it at that?
i've got a 1.6 but will be using the injectors off the 1.8 NB (230cc i think), and aiming for about 8psi boost (with hopes of a very occasional increase to about 12psi), with a megasquirt.
i was directed here by "aussie driver" as he says you guys know your stuff, and it sure seems so reading through this info. it's great, cheers.

With the 190HP and 1.8's you will need an AFPR to boost your fuel pressure. You should shoot for about 80psi of fuel for 8 psi boost with 1.8 injectors. The difference is that the 190 HP can put out good flow at higher pressures, but you need to restrict the return to tank flow to get the pressure up there.

Read my faq for a little bit more understanding (or tons of consfusion) about the fueling situation. But yes, a FMU be required to raise the fuel pressure in the rail effectivly raising the fueling potential of said injector.

thanks olderguy. so do you think it might be better just to get some bigger injectors and not use an afpr? i have already purchased these injectors but i should be able to send them back and get some bigger ones.
as i said i'm aiming for about 8psi at the moment but would like to eventually get to 12psi boost.
so of the 3 combinations below which do you think is best for that target
1 - 1.8 injectors + 190hp + afpr
2 - bigger injectors (supra?) + 190hp
3 - bigger injectors (supra + 190hp + afpr
4 - something else ? ?
