Volvo 340 B18FT Fuel pump
Hello guys, could you help me I searched for all the topics related to swaps, and I couldnt find anything. I am doing my swap from volvo 340 1.7 to b18ft, and what fuel pump should I use, I am looking for something not expensive, because 440 fuel pump is in the tank, and is not fitting in 340. Please help, thank you.
Re: Volvo 340 B18FT Fuel pump
Presumably this is an injection conversion from carb. I don't have a solution for a 340 but you will need an in-tank pump or a bottom outlet from the tank with a 12mm pipe to an external pressure pump. There is a thread about with someone who put a bolt-in union in the bottom of the tank, might have been a 360 tank, but the principle should work if you get it in a baffeled area.

Re: Volvo 340 B18FT Fuel pump
I think fitting the fuel pipes are the easiest part, for me its is harder to know what fuel pump to put, I have seen someone had put subaru fuel pump, but from what engine he havent mentioned, and I have read that someone was using BMW 318/320 fuel pump, these ones think I would get very cheap, but I dont know will they be enough or too much for the engine. And its not neccesery to put in tank fuel pump, it would be a lot easier to put an external pump, but what kind of?
Re: Volvo 340 B18FT Fuel pump
I thought that would be much easier. Its really about pressure and flow which is probably 140lph at 3 bar. The B200s can all use the 1 pump for 120 to 200 bhp easily, you can buy new for about £30.
If you are pulling out the top of the tank you need an in-tank lift pump for an external pump, injection pumps do not suck as well, also the original carb pipes will be too narrow for injection flow rates. A top fed pump might work a bit but will be unreliable with cavitations causing pressure loss occasionally.

Re: Volvo 340 B18FT Fuel pump
Did I understood correctly, volvo 360 inejction fuel pump fits in the 340 fuel tank? Or it needs some more modifications?
Re: Volvo 340 B18FT Fuel pump
No its an external pump, the injections use a bottom outlet tank, but you cant fit a 360 tank to a 340 without the engine/drive conversion. An external pump can go anywhere really but needs to be connected near the bottom of the tank unless you use an in-tank lift pump. But if you are going to make an in-tank lift pump fit you may as well fit an in-tank pressure pump. You need to fabricate more stuff to fit in-tank pump, this is why I suggest a bottom outlet and use a standard external pump.
All I am saying is standard injection theory, I don't know how people make the b18ft work.
