just wondering where the fuel pump is on a lly motor ....
is it like the gassers and in the tank????? i dont think so, but i am not sure?? how do these systems work......
what kind of fuel pressure do they run in the line ???
in the rail to injectors ??? in the injector ????
do they have fuel heaters , in the tank ??

any info would be great !!!!!

also what intervals are you guys changing fuel filters at ?? my milage is at (1250)

thanx the05hd :)

There is no primary pump, only a high pressure injector pump that is driven from the cam gear. It sucks it from the tank and through the filter. Most guys are changing the filter every 10K, I think the books says 15K. Injector pump produces up to 26,000 psi, computer determines pressure. There is a fuel cooler just in front of the tank.
