Hi Iam have in a little with the k series it keeps boging down after about an hour do you know what this is

 

There is not enough information here.

 

Which engine do you have? Which MEMS ECU are you running. Is it ok for an hour then "boging down"? I don't even know what you mean by that, lumpy running or misfire, at idle or normal use etc???

Yea sorry it's mems 3 I think it's emerald ecu when u put your foot down yea it miss fire then I have to start it again

It's not lumpy running it just bogs down after a while I think there's dirt in the fuel which blocks something

The fuel injectors could be getting clogged with debris in the fuel. It's not common, but does happen.

 

Try piping the fuel lines without the fuel filter. That will prove it's not that.

 

Next, are you using a MPi fuel pump? The SPi model looks exactly the same but isn't powerful enough. Can you get a pressure gauge on the fuel line? You should be running 3 bar. The SPi will only give 1 bar.

 

Hope this helps, Andrew.

Ok I will get a pressure gauge and I have extra fuel injecters thanks mate for your help
