16” of fuel line from bottom of pump to rubber fuel line adapter
This is what it will look like once you are done!
Instructions
Pull cover from between the seats and 3 philips screws and remove metal cover. Check to see if there is a mark showing the orientation of the clamp ring. If there is no mark use a silver sharpie or something similar to mark it. Carefully remove all connections. All have 2 sides that need to be pressed. Some of the second sides are on the bottom. If pressed they should wiggle off without pulling very hard. There are special pliers that help make this easier. Lots of photos from 3-27-25 Remove seat plastic with 3 T15 screws Remove upper and lower access covers between front seats to access top of fuel tank Clean the top of the fuel pump and tank with vacuum and or compressed air Protect regular fuel line with a deep socket and cut top of aux line right below clip rib Run an 11/64” drill bit through it to open up the hole up enough for the plastic line to fit through Slide new fuel line down Cut the factory black line on the straight part that the other fuel line no longer fits inside of Slide espar fuel line down Take a piece of the line that was cut off and slice it down the middle and slide it over the espar line. It’s a very snug fit but if you put the slit factory line down in the clip in the fuel pump with some pressure it will slide through. This way the line is well attached to the pump and having it stay snug is important as if it pops out the customers heater will stop when there is still plenty of fuel in the tank. If it’s too snug to pop in cut the part down to about a ¼” and that makes it easier for it to pop in. Use something metal or hard to push with as your finger may not be enough. Take the adapter and cut it shorter so it is about the same length as what’s left of the AUX line that you cut down Spray some windex or similar onto the espar line and slide the adapter down the line until it goes over the AUX line. Use the bigger clamps that come with the heaters and clamp to the AUX line and espar line. You can now pop the fuel pump back in. Be careful not to break any of the lines going to it. Orient it back to how it was and have the bottom of the pump directly below and press down. Take the ring and slide it over. Line up factory chalk line so once tight it will line up. You should be able to get it on just enough for it to stay down with your hands. Then get the tool, ½ ratchet and a little extra pipe. It takes real pressure but will pop into place. You will see the white chalk line line up. Connect fuel and electrical cables Slide 7ft of split loom over Espar line and give it a little pressure and then some electrical tape to hold it in place with a little pressure pressing to the pump. Now route the line backwards and down. It should be an easy bend for the line out the top. Go ahead and put the metal cover back on and the floor hole cover. Be careful not to push the plastic threaded inserts out the bottom of the metal.
