fuel temps, IP/injector cooling
 

Does anyone happen to know... on average.. what is the fuel temp of diesel by the time it hits the injectors and what the temp is when it leaves the return lines.

also what all in the IP injector path is by design and by neccessity cooled by the fuel anyway?

Just thining of WVO stuff.

THANKS

PS. Yes I'm assuming their are a few different answers such as one for common rail IP's and ones for other types of IP's. I just dont know all the type of IP designs well enough to ask broken down by type. THANKS again.
