I have a 96 D1. 86,000 and i doubt the fuel filter was ever changed by the previous owner. is it common after all this time for the fuel filter to be pretty clogged? how important is it to change? | ||

yeah, change it, might be restricting flow, car will run better and they are cheap and easy DIY project. rd | ||

It's super super important. The first time I pulled the fuel filter and banged it against the ground, rust fell out. I'm like, wow, good job filter. I was in the same situation as you, whereas I dont think the previous owner took great care of it. I recently pulled the fuel rail off, and pulled the injectors to get them serviced (cleaned, new screens). I could never have imagnined the amount of rust that was in the fuel rail, injector housings, and injectors. For a 3-5 dollar part, that's something I replace often, just do it with every oil change, it'll make you feel better knowing everything is good. | ||

Gee, you don't suppose my hard starting and rough idle is due to my eight year old 169K miles fuel filter, do you? I'd love to replace mine, but due to the boogered up fittings, it is going to be yet another simple job that will require Herculean efforts. Maybe I'll actually get a chance this weekend, I have the filter and fittings. At least I have clean injectors... Peace, Paul | ||

Heh, paul, yeah I had a lot of rust that fell out of the filter the first time I replaced it. I was amazed. I was also told, by the person who serviced my injectors, that I should remove at least the supply fuel line from the filter -> engine fuel rail, and have that cleaned, since it's going to have rust too. Looking at how they route, that's going to be a big problem, since there is no easy way to remove that line. I'm going to disconnect it at both ends, and blow some shop air through it, to see how much rust I get out. I'll let you know the result. | ||

I replaced my fuel filter after 120k and it made a huge difference. Rough idle is non-existant. Its an easy job...even if there is rust. | ||

Is there a after market part so I don't have to pay LR. | ||
| Jared Schnelle (Jared) Member Username: Jared Post Number: 102 Registered: 09-2002 |
Nope damien, it should just appear to be a can with 2 welded nuts on either end, then when you put it in the fuel line, the threaded nut(? heh), screws into the filter. | ||
| Jared Schnelle (Jared) Member Username: Jared Post Number: 103 Registered: 09-2002 |
I believe what I called the threaded nut is called an AN-Fitting. Just to be clear. | ||

Thanks a lot. this could be causing my lagged start and power loss issues | ||

An AN fitting is a particular type of fitting using a tapered flare as a sealing surface. As for the importance of doing this, I have replaced injectors and have been amazed at the size of rust particles that collect right at the injector inlet. Based on this, I can only comment that if this much rust is being found on the outlet side of the filter, the filter can only be seen as being of marginal benefit as far as removing rust is concerned. Also, there is a filter attached to the fuel pump... FWIW-it is common to remove the threaded fittings and use hose barbs and hose clamps. I've been told by LR parts vendors that LR offers a retrofit kit that allows you to do this, however, yo can cut the ferrules from the hoses and this exposes a hose barb that can then be used to retain the hose and similar hose barbs screwed into the filter. The filter threads are 3.8" NPTF. |
