Hi folks,
As I am wrapping up the body and suspension works this month, I am moving onto learning about the engine components going forward. As I've had this nagging whirring/pulsing issue going on with the stop lever, going to do a biodiesel (or possibly wvo), and also after examining a few fuel hoses, I decided that I am going to replace all the fuel lines and filters. I plan on placing an order with McMaster or some other online shop tomorrow, so I'd like to make sure I order enough and the right kind of hoses, so my apologies for the newb questions. First, I took a picture of the engine bay and labeled what I believe are the fuel delivery lines:
I have the rear axle dropped right now, so I am going to replace the return and supply lines (4 hoses total) back there. Those are pretty straight forward.
Questions:
1) Regarding the three plastic lines coming off the fuel filter, what is that material made of? Its obviously some sort of plastic. And second, I tried to wiggle these hoses to see if they were loose, but they are tighter than all hell. How does one get these things off?
2) Is the return line correctly labeled?
3) Is the supply line correctly labeled? Or is the line going into the pre-filter the supply line?
4) From the pre-filter, there is a hose going to some component. That component has 2 (maybe 3---i can't recall right now) hoses coming off of it. What is the name of that component? Is it some kind of fuel thermostat?
Thanks to all for any help.
Bob
