i just got a crx with a jdmb18b
it has a walbro 225 fuel pump is this necessary? seems to be drinkning down fuel

 

it's not necessary, but it won't cause bad gas mileage. something else is at fault for that

 

stock injectors?

I put a walbro in my hatch with a udsm b18b (stock injectors) and notice no difference in gas mileage.

 

yeah its stock injectors as well, is this fuel pump louder? slight humming sound?

 

high flow pumps are used mostly for turbo setups. do you smell gas when your driving or what?

 

no i dont smell gas at all, just sucks it down it seems like
also noticed there is 0 vacume lines ran could this be a problem? i know theres some you need but all of them? i cant seem to find a diagram for this

 

yeah, the pump is louder than stock when it primes for me but this is normal. I can't notice any difference in noise when driving.

 

Vac lines where? For the fuel rail/fpr?

 

just the smaller vaccuum lines none at all ill try to get a pic on here

 

Hmm, if you have no vac lines, then your fuel pressure regulator isnt working.

hopefully this works and will help
sorry i only had my phone on me

 

What vac lines did you say are missing? Because everything fuel related is there.

 

usually you see line running here in most swaps

(mpfi swap is ghetto) this is the way i recieved the car needs work still haha

 

MAP sensor is there, it looks like you have an obd1 throttle body, so the MAP sensor is located ON the throttle body.

Every other vac line is NOT needed. the purge solenoid is not needed, neither is the charcoal canister line.

 

ok the only one i knew i didnt need it the throttle body line..
if its obd1 how come i have the (amp looking) resistor box still?
do you have to jump a wire to see what check codes your throwing when this swap is done?

 

The the intake manifold could be obd1, and the fuel injectors could be obd0.

What ECU are you using?

 

aalright that makes since. this is one of the most ghetto swapped cars ive seen the price was well worth it though thanks for the advice

 

Get the fuel injector wiring shield (plastic piece that holds the wires and bolts to the fuel rail) and tape up then rest of the wires.

By the way, our cars look similar, based on your avatar.

 

this weekend its all getting fixed/full tucked/ and gold bay as long as the weather stays nice

yeah i used to have a 91 lx it was auto though ,it was my dd for awhile full tuck/semi shaved bay its was pretty dope for an auto 1.5
