on a volvo k-jet the fuel distributor is kinda buried under the intake manifold and not nearly as obvious as it is on Mercedes or VWs with K-Jet... the eaesier thing to see is if the injectors are on a rail and have wires running to them, then its definitely LH.

1990 Mercedes 300E KE-Jet ...


(shiny clean fuel distributor and airflow meter because I'd just taken it all apart, cleaned the distributor and replaced the fuel meter).

 

yes the Volvo doesn't have the fuel distributor it has k jet I believe but I don't see a valve on the fuel rail anywhere to check pressure

 

if you have a fuel rail, you have LH Jet not K Jet.

early LH didn't have a valve, you need a T-fitting, and remove the incoming fuel hose, install the T, and connect the fuel pressure gauge to the T, then start the fuel pumps. if the engine is running, you need to disconnect the manifold vacuum line temporarily from the fuel pressure regulator to get the correct reading of 36 +/- 2 PSI.

 

in coming hose meaning the one by the firewall to the fuel rail?

 

yes, there's two fuel hoses, one connects directly to the rail, thats the pressurized fuel from the fuel pump. the other connects to the side of the fuel pressure regulator, and is the low pressure return line back to the fuel tank.

 

ok got it so what do I do next
