Fuel Lines
Fuel injectors and fuel rail will come pre-installed on crate engine. The fuel rail is a non-return style fuel
rail. Use only fuel grade hoses and fittings when installing fuel system. Fuel rail inlet size is 3/8 inch SAE
quick release. Fuel pump must deliver a minimum of 222 Lbs/Hr at 58.5 psi. A Fuel Pressure Regulator
(FPR) is needed for this non-return style fuel system, the FPR can be external or internal to the fuel
pump. The FPR should be placed prior to fuel inlet on fuel rail. Follow diagram below for FPR layout.
Vacuum
Vacuum reference can be taken at the fitting at the
back of the intake manifold. This can be used as the
brake booster vacuum line or any other vacuum
reference needed. If not being used, cap this fitting with
a 3/8 inch ID vacuum hose cap.
Oil Filter Adapter & Cooler (6.4L Only)
The oil cooler mounted to the engine may be removed and
the oil filter can be used without this cooler attachment. To
eliminate the cooler, a threaded oil filter connector part
number 04892338AC, will need to be used to allow the oil
filter to thread onto the engine block. To utilize the oil
cooler, connect coolant lines to the two fittings; either
fitting can be in or out flow.
