coolant is very easy, I will either modify a 2.5L goose neck filler or get a in line filler adapter from jc whitney. The drivers side pretty much lines up when you use the rad hose off a 2.5L. The pass side just need to be routed using a flex hose and fastened to the chassis. The fuel lines will be high pressure fuel hoses from the pass side, under the reails near the trunk and out the middle of the engine comaprtment.
the heater core tubes need to be extended and brought to the pass side, I will also use regular mater pipe plumbing (coper tube) to extend away from the super charger belts. then attach to the rubber hoses.
Fluids won't be a problem at all. the problem (or difficulty) relies in proper routing of the wiering.

I want it to be neat. but that can be adjsuted and rerouted after the engine is installed.
