Heater hoses and Fuel filter hoses

[s13point5]

can anyone tell me which heater hose goes to the top nozzle on the firewall and which one goes to the bottom nozzle on the firewall or does it matter?

as for the fuel filter hoses. does the hose from the top of the filter go to the back of the fuel rail or to the FPR side of the fuel rail first? i did search for both these questions but i couldnt find the answers i was looking for.

I don't think it should matter on the heater hoses but I'll let someone else confirm that

For your fuel hoses:• fuel pump hardline to filter• filter to back of rail (DO NOT HOOK TO FPR)• out the FPR to tank return hardline

FPR works by restricting the return of fuel to the tank. If you hook up your hoses wrong, the FPR will restrict flow into the rail and you probably won't get your engine to start.

perfect answer for the second question. thank you

one more question. the hardlines which are connected to the fuel rail by hoses are laying on top of my greddy intake manifold. can i delete those and just run hoses from the fuel rail and route those under the intake manifold straight to the fuel filter and return line?

That is what I did with mine. I ran the return straight off the FPR underneath the manifold to the return line. Then, I cut the fuel supply hard line on the rail towards the rear and ran my fuel line under the intake manifold from the filter. I tried to flare the supply line as much as I could and am putting two hose clamps on the line to make sure it doesn't leak or come off.

About the first question , either side will work for the heater hose !

Its about the same as a front radiator , the fluid will make his way from a side to the other
