Default fuel line adapter

Hey everyone i have a engine from a 1990 ranger and i am putting it in to a 1989 bronco 2 and ever thing was going good with the swap but when i went to hook up the fuel lines i noticed that the fuel lines on the ranger engine is bigger than the bronco 2 lines i have been looking everywhere to finds a adapter but no luck. I don't want to change the fuel rail just to get it to work because i think i have to take the intake off and if anyone could tell me the exact sizes of the quick disconnect coupling of the ranger and bronco that would be great something like 6an or 3/8's

+1 on the pics. Swapping the fuel rail is not as bad as it seems.

i swapped the fuel rail today and got the engine running. It runs untill you give it some throttle and then it acts like it wants to die. It will run at idle but not very long. I think it might be because of the o2 sensor. On the last swap(this is our third) we accidentally ripped the wires out of the sensor.(cranked it without sensor) So i took it out and today i am going to the parts store to get another. I also have two more problems its dribbling coolant somewhere near the bottom of the water pump and i have no rpm gauge. thanks for the help

Should run half way decent w/o o2 sensor connected when cold. The o2 sensor is heated and isn't used until the computer system goes into closed loop. Should still run when warm, but will default to what turns out to be a rich mixture. Coolant leak could be water starting to leak out of the weep hole, sign that the water pump is going bad. Thing to look for is water building up/dripping off from under the water pump pulley.

I would be watching the fuel pressure when it's running and checking the computer for key on engine off and continuous memory codes.

i have nearly fixed every thing turns out i had a bad fuel regulator and two or three injectors not working. for reference any one who needs to check if there injectors are working. You just take your fuel rail off,unplug the injector wires, prime the fuel pump and use a jumper wire connected to a twelve volt battery and stick it to the positive contact on injector and and negative to negative. it should squirt like a water gun. also you have to prime the fuel pump again to check another one.
