almost no acceleration
i was driving back home from a 3 hour highway drive and once i got off the highway and stop at the stop light off the exit, when i went to go again, i had to push the accelerator almost all the way down before anything happened, the acceleration was so slow and sluggish. my fuel gauge doesnt work so i use the odometer and its at 270 right now, do you think this sluggishness is due to the low fuel?

Could be a dirty filter(s) too.

I'm gonna go out on a limb and guess its a 123.123 or a 123.133 ....
The prefilter is almost self explanatory....screwdriver is your main tool (unless you have new hoseclamps and want to use a nut driver) Main filter is a spin on. There is a nut on top... if you loosen it, it will help you take off the filter. If memory serves correct..there is a copper washer that will want to be replaced. After you are reasonably sure that you have replaced everything correctly, you ought to find the primer/hand pump, and prime the system until the bubbles are gone. Turn the knob on the pump counterclockwise until you are able to move the shaft up and down (as if it were a bicycle pump) However....if my guess is wrong, I just wasted 2 minutes of my time that I will never get back, and it will all be your fault, and you should loose lots of sleep over it.

i just replaced the fuel filters on my new 1985 300D for the first time, and i had some fuel spillage. not much when i replaced the inline filter, but when i unscrewed the main fuel filter, it was full of DinoD and it spillled on the grass. (killing it, i looked today, all brown after 2 days) i was not sure how much priming i should do, i read until bubbles were gone, but it seemed like when i was pumping that there were air bubbles comming up and out of my IP. so i just kept pumping until i had diesel running down on the concrete adn there was a nice puddle. next time i dont think i will need to go to these extremes, but it was my first time, and i was nervous...

You may also want to check your throttle linkage adjustment just to be sure.

I'm going to go out on a limb here and say that it's not fuel filters.
My argument is as follows: You had the vehicle out on the highway at 3000 rpm or more and it was fine. The fuel flow was approximately 2.5 gallons per hour. Then, you stop at a traffic light. The fuel flow drops to about .5 gallons per hour. Now, it feels sluggish off the light. But, the fuel flow is significantly less than the fuel flow on the highway. So, if the filters were bad, the engine would have slowed on the highway. I'll be curious to see if the filters help. I will tell you, however, that the SDL did a similar thing when the fuel got down to the last two gallons. Significantly reduced power in all operations. Filling the tank didn't correct the problem until the vehicle was driven another 100 miles. Then, it cured itself and hasn't had a problem since. Interesting. |

The fuel rate is not very high when coming off idle because the rpm's are too low. The rack won't allow all that much fuel. If he felt sluggish at 2000 rpm or above, I'd agree, but, right off idle there is no fuel restriction. I agree that you have to replace the filters to rule them out. That's why I'm curious to see what the outcome will be. I think the clogged screen is a definite possibility. I really wanted to change it when I did the two hoses, but, did not have the proper socket to get it loose. |
