I did this. Some mates and I put a B18C7 into a carby EG. Bit of work and big pain in the ass. But I used the DC2r loom so didn't have ur problem. I bought new fuel lines, fuel tank, and other shite. I have the memory of a goldfish so can't remember much else. Do a quick search. Plenty of ppl have done this.

i have done this aswell
wat i did was buy a smash fuel injected eg. wat u will have to do is use the full dash wire loom for fuel injected plus fuel lines nd tank. u will need a d15 loom nd ecu. i will posst more here once i remember, its 2 late in the nite now. pm me if u need more info

i'm currently going through the same process
and have noticed that the fuel lines are quite similar
both carb and efi models have a fuel feed, vapour and return line
is there actually any difference between the lines
which i may have missed?

yes the pressure the lines r under, i think the efi line have to go under alot more pressure then the carbi line, naa the carbi lines will not handle it.

I had an 85 civic hatch that was supposed to have the carby 1.5 sohc wheezer, but
instead it had a JDM ZC twin cam 1.6 injected swap, and went hard (15.5 wsid stock engine, 890kg car), sold it. Now have an 89 LS integra 1.8.

Nearly all of the wiring loom was swapped out for the fuel inj car loom, big job but worked as per factory as we used the cluster from the injected car too.

Stock fuel tank was kept and an inline fuel pump was plumbed into the stock line out of the fuel tank. Efi hose was then used from the pump to the hard lines.

Ecu was bolted under drivers seat.

Hope that helps.

for those who are doing a conversion from carb to efi
i suggest you not, but if you are, make sure you buy
the lines and the tank together and make sure the
high pressure hose running from the return to the fuel
pump hasn't been snipped off.
otherwise you'll have to replace the hose fitting which
could be a little more cost. if you can save that cost
in the first place, why not. some wreckers are just
lazy and cut the hose.
OR
you could ghetto the hose fitting with hose clamps.
not a good way to go about it as fumes or fuel
leaking and a hot summer day is not a good combination
don't try it kids.
