FPR Before or After Injectors

[RT40Corona4AGTE]

I too agree with TERRA! But am not sure how relevant it is, as you have said this isnt a photo of it with the FPR installed.

TERRA

can u upload a pic of ur setup if you can...

OEM FPR was fitting in Gear-box side thats why i connect that side to Sard and filter out put to cam side

even if i put Sard FPR according to Diagram it gonna be like Out put form Rail(Gear box side) to Side of the FPR and Bottom out of FPR to rturn rail...

I think you have yours a bit mixed up?

It might not make much difference, but on my GZE, the inlet (with the damper) is on the gearbox end of the rail, and the outlet with the adapter going to the Sard is on the cam belt end.

just looked at my gze and my n/a motor, gze is as you have explained, but n/a is as pictured above ( red top anyway).

Is it possible that the fuel pump you have used is pushing far more volume than the return line can handle, thus with fpr before rail volume is reduced allowing only a low amount of fuel that needs to be returned to tank?

BTW, your mechanic/engine builder is an idiot!

it can be Fuel pump is sard 160L, but i knw ppl run Walbro 255L with stock FPR,

I knw Engine builder is Old-School (its a Rally-work shop and he/they build all clubmans etc... thats why don't know whom to TRUST )

If it's WRONG SARD WON'T PUT THAT DIAGRAM
only thng i can think is miss match fuel pressure in fuel map and FPR

lets c.....

Unfortunately, my engine is half dismantled, so I can't take a picture... I'll see if I have a picture already taken on my computer somewhere.

check the tune...

I thnk it's mis communication over phone (Daam Russian, hard to understand )

this is how engine builder set-up (as he said)



he's trying to explain to me according to diagram if he put Rail out put into side of the FPR and bottom line to Return line then it coughs won't keep pressure every unstable
and when swap the line then it was fine bit rich under 2.5k runs smooth over 3k

i thnk base map is shit anyway i have get it tune.

that doesnt seem correct either, the bottom of reg's that style should go to the return line back to tank and the side port be fed from the rail.
unless there is something "special" about your SARD FPR for some reason? I am pretty confident that how it is setup in that photo is completely incorrect though!

[thechuckster]

what he ^^ said - the mechanic has got the regulator back to front - sides are for fuel in from rail, bottom is return to tank, top is vacuum reference. Doesn't help that he's mounted it on its side.

edit: it's pretty simple to check, the port that has the gauge in it should be open to the port connecting to the fuel rail.

edit 2: just check that the thing bolting the fuel supply (from the filter) to the rail is in fact an anti-pulsation device not another FPR.

As above. FPR is connected wrong way around. Swap the fuel rail line with the line going to the fuel tank and you'll be sweet. turn the FPR the right way up so you dont make the same mistake again

I restate, your mechanic is a retard

[Animal15]

we hookd it up other way (swap line) but i drops pressure even adjest form top nothing happened. car won't even ideal

something is wrong then, can you disconnect your fuel line from your filter to your rail and the one from your FPR to what you think is the return hardline back to the tank. Then turn the key on and confirm that the one the filter is connected to is definately the feed from the pump? ie. fuel pisses out of it when the pump is running?

I reckon these may be around the wrong way, no other real explanation really.

[Animal15]

lines are right man (cause after i convert to AN fittings , we crank it , then fuel filter washers are not tighten enough and fuel piss through line fit to filter )

and when we stick an airline on bottom side you can hear sound but do it to side one can't hear anything.

(after i did bit more research few ppl had my problem (in some supras, rx7) after they swap the line every thing was fine ............. don't know it's weird)

i'll take it to tune then talk to the turner and go form there...

[RT40Corona4AGTE]

fair enough, i have read about that as well, seems very bloody strange though.

please let us know what the outcome is? I am interested to see what it actually is.
