i have two dual 4 setups one in a car with repro fuel log and another original and both have a 90 deg fitting at the front which angles the line infront of the
oil tube. this causes the line to run from the mech fuel pump along the bottom of the oilpan rib and then snakes up the left side of the front engine cover and pops out to the right of the thermostat(perspective from front of car looking into compartment) a tight fit to say the least. on my running setup i have relocated the factory line as to not super heat my fuel it will perculate out the
venturi's when the car is shut off. the steel line acts like a heat sink and absorbs all the engine heat.note the fuel log mount at the rear of the engine
must start on the second intake bolt from the back
