i'm currently finishing up the ca18det swap in my 74 b210. i have not started the engine yet. i have the fuel system all hook up but ran into snag. the first one is that i think i got the wrong fuel pump. the pump i got flows 43 gallons per hour. this equates to about 163 liters per hour. is this engough to feed my ca? does any body know how much the stock one flows?

the second problem is that when i was checking to see if the there where any leaks i noticed that the fuel circulates through the lines and gets to the fuel rail just fine but it does not stop there and hold pressure. i know this becuase if i put some pliers and crush the return line it begins to hold pressure. is this normal? shouldn't the regulator hold the fuel pressure. is my regulator bad? or will the regulator start to work when it starts to get vacuum. any ideas?

That fuel pump is fine for a stock CA18DET.

Yes, pressure should build up in the rail, even with the motor off.

Are you sure you have the fuel path correct? It should go tank>pump>filter>rail>regulator>tank
