FPR question
 

ok im gona purchase one (fuel pressure regulator) probably used so i need to know if all of them are the same for like D series engines from Cx to Si model or they vary and how long do those things usually last? thanks

If you're geting the B&M one where you cut the stock FPR in half, I think it fits just about all 88-00 Civics and 90-01 Integras.
The only diff on some years/models is the angle of the return line "nipple" from the FPR.

make sure to get a fuel pressure guage as well, you don't want to guesstimate your fuel pressure.

im talking about OEM cause the valve on mine is broken and i just wander are all honda d series fpr same for all the models

oh ok....then you don't need a guage.
