I just completed my ef hb si b18c1 swap. Well heres the thing. My gsr b18c1 swap did not come with a oem fpr... so what i did was use my stock d16a6 one...

<FONT COLOR="green"> Do you think they have the same psi setting in the diaphram?..
I would hate to be running lean. </FONT>

Wish I could help you out and give you a definite answer. I was kinda wondering this myself. I could only speculate and say that the d-series fpr will run a little leaner than the b-series one.

 

The FPR's on B and D series, and also H series are exactly the same part number, so no difference.

hum... how can the be the same part number cause if you look at say a gsr compared to what a d16 fpr they look different physically.

Also how come the flow rating on them read different? (see link)

Part #6 (which is 19571 part # on that site) on this picture:



and for a 2000 Civic Si (B16):

Part #6 which is also 19571.

B16 and D series are the same. I don't remember the GSR or ITR's off the top of my head though. Been a while since I have compared them.

The B20z FPR is not the same as the other B-series.
I know that the LS FPR is also differently shaped vs. the B16a1.

different shaped does not mean different internally.

They may be the same internally, but the B20z has a completely different hole pattern to affix it to the B18 fuel rail. The B16 fpr's vacuum nipple faces the wrong way,

In my book that classifies a part as being different

 

GSR fpr #16740-P72-003
ITR fpr # 16740-P73-003

so I'm not sure both internal diafram are set at the same PSI.
