Injector Replacement Questions 87TD
I had some Questions about replacing my Injectors, I know I will need new Washers to go under the injectors, and I have read and have been told how to properly bleed the air out of the system. When I have the injectors out, should I replace the Injector Over flow line, the Cloth covered line that goes form injector to injector? I dont know if there is anything wrong with the current ones, but I assume that they get changed with the injectors, correct?

Aqua,
Buy a yard of the injector return hose. Its not that expensive. You will most likely break some of the lines getting them off. I just use a box cutter to get them off the injectors. The hose tends to get hot on the injectors and goes hard & cracks in time. When you have the injectors back in, just cut new flexible hoses to suit. That way you should have no leaks of fuel.

Yeah, might as well replace those lines. AFAIK that engine uses the same injectors as a 617.

If you use any sort of cutter be sure not to nick the little nipples that the Hose hooks to in the Injectors as it can cause a leak.
Since you are removing the Injectors you could just cut the Hoses close to but not onto the nipples and remove the Hose ends after you get the Injectors out of the Engine. After about 4-5 years (or sooner?) of use the Fuel Return Hoses/Lines looses elasticity and when you remove them it often causes them to leak if you put the back on; even if you cut them shorter.

Thats what I thought... This is an old Tan colored Cloth covered Tube, I dont know if they are original which is doubtful but I figured I would have to replace them

Get yourself some Viton hose and you can forget having to replace the lines when they start leaking, because Viton will last a decade or more as it doesn't lose its elasticity or get rotten.

My Volvo also uses the same Hose on the Injectors and I have also used it as Vacuum Hose and Window washer Hose.
