Fuel Filter in the carburetor and under the fuel pump where it attaches to the engine. Not aware of a filter on the power steering pump. I would change the power steering fluid and if the steering is grabbing I would use a pint of Trans X and then change the fluid after a couple of days running it.

 

Thanks for the input Shak, now just to be able to try to find a fuel filter like the one I have I don't know that it's possible? I'm going to take photos but the cars in the shop I'll let you know what I think is the fuel filter maybe this thing next to it is the fuel filter? There's a little confusion here?

 

Folks;
There are 2 fuel filters on your Eldo...one is in the mechanical fuel pump. The 2nd is where the steel fuel line enters the card.
My 1970 SDV 7.7 liter has a similar mechanical fuel pump on the front left of the engine.
At either end of the steel line between the pump and the carb is where the filters are.
The main paper/fabric fuel pump filter is accessed by removing the fuel line and the the large nut between it and the pump. These filters are very cheap thru RA. I buy a handful and change them yearly..........Good insurance as we have gas tanks that are 50 years old!
The filter at the carb entrance on mine was a porous rock-like devise. I changed it with a small paper fabric one as the orig had 100,00 miles on it! Don't know where I got it...sorry.
But I also installed a 3rd see-thru filter half way along the the pump to carb steel line.
I've had my carb rebuilt twice and it hums.

Good Luck.

... ..one is in the mechanical fuel pump. I never replaced one on the fuel pump itself, is it under that outlet feed going to metal line up to the carb?

 

Folks;
nphx..., note.. in my pic #1 it shows 3 nuts where the steel fuel line attaches to the bottom of the pump.
To access the main filter in the fuel pump -
1.you gotta unscrew the lower smaller nut (in my pic #1) that attaches the steel fuel line.
2. next you gotta unscrew the middle nut. This allows the spring, gasket and filter to drop out of the fuel pump.
Easy

tip.....have a drip pan and paper towels ready as there will be gasoline dripping out..NO Smoking!

Hi King I meant to get back to you sooner, is your car a fuel injected car or a gas car? My car is a gas car I know the fuel injected cars take a long cartridge cylinder in addition to the small cartridge cylinder at the carburetor which vehicle are you talking about the carburetor edition or the fuel injected one? Which one do you have because mine is a gas motor and all I can see on the car is that weird little coffee cup thing with fuel lines going to it "see pic" I've already replaced the small one

at the carburetor maybe you can help me out here? Hope you had a Merry Christmas thanks for all your help!

 

Is it a small round disc filter that goes inside of that coffee cup thing or is it a long cylinder type?

 

Folks;
Akas, my 70 SDV is very similar to your engine. Mine is gas with a mechanical pump like yours. My carb is Rochester QuadraJet
According to Rock Auto the mechanical fuel pump was similar in years 1969 - 1976. RA has the filters (cheap) that go inside the pump. They are the long thin orange filters.
As in your pic the filter is accessed by 1st removing the steel fuel line, then remove the next nut it is connected to. Then the filter falls out (it has a spring be careful). I believe my filter was the Hastings GF87 . RA lists GF87 the same for 1970 and 1976 for under $3. Get a couple of spares.
It's easy!

Thanks once again King! I get it now it's just so different from the modern cars it was hard to take a grasp at what you were talking about but I just ordered the GF 87 filter it does look like it would slide into where you're talking about that little hole up "fuel line port underneath the coffee cup"there that's awesome cuz I don't know if that's ever been replaced it should make a big difference even though the car runs pretty good! In regards to the power steering unit filter I've been told a small little inline filter will be good and that's what people are offering in the auto parts industry so I'm going to go ahead and replace the power steering unit and put their filter in there unless you have any info or somebody has a better filter for the power steering unit thanks for all your help!

 

I want to say that I found the filters locally for my '72 just by bringing them in to a parts shop.

Also, for the fuel pump filter, there is a huge nut holding it in; outside of what normal sets have. I want to say it was something like an inch and a half or larger.

 

got a picture?

 

Here's a picture of the power steering pump filter and the bottom of the fuel pump canister in which I have been told that I can take the filter out by turning on the bottom of that big screw in fuel line nut

to replace the filter inside the can anyway here's the photos.

 

I just took this under my '72 Eldorado.

the red arrow points to the one holding the filter, and the blue to a nut that probably needs to be removed to get the socket on it.

The stray large socket in my cabinet is 1-1/4", so that's probably what you need.

 

Yeah thank you Hawk for the update that'll be a help when I go to do the work!

 

happy hunting.

Oh, and when you do, don't forget that's front drive when you jack it up.

Not that I bent my bumper jack that way . . . [the parking brakes can't latch]

 

That's pretty awesome the car has like three fuel filters when you think about it a strainer in the gas tank a filter at the fuel pump and then a filter in the carburetor I don't know too many cars that have that many filters just two that I know of usually, I guess that's why you paid alot of extra money for these cars!

 

Don't count on the one in the tank still being there, unless you've seen it!

When I dropped my tank, the strainer was completely gone.

(if you do drop the tank, the FSM encourages rinsing with hot water.

I hauled it through the house to use the bathtub--to my wife's dismay!

Later, someone pointed out to me that household hot water heaters have a drain that takes a standard fitting.

If memory serves, the filter at the pump was quite clean, and I only replaced it due to the amount of work I'd put into getting to it.

Also, many longtime Eldorado fans will insist, incorrectly, that the pump filter does't exist!

Oh, while I'm at it, if you take the pump off (replacement, whatever), the upper bolt is only a "U". So if you loosen it, and remove the lower bolt, you should be able to get it off without the adventure of putting the upper back into its inaccessible hole.

 

" I hauled it through the house to use the bathtub--to my wife's dismay! "

😆 What women have to endure with our reparation repairs on our classics!

Thanks Hawk, I wonder if you recommend since I'm in there wrenching just to go ahead and replace the fuel pump/mechanical fuel pump and if so do you have a recommendation because I don't want to get a cheap Chinese one. I'm not having any issues with it but I'm just figuring shoot it's close to there or something maybe I should just replace it too your thoughts? I have not removed the fuel tank I don't know if I should I think it's fine because I didn't get any debris at the carburetor but still there could be some debris at that other filter? Paul

 

I really don't remember; I certainly don't have a quality recommendation (well, other than to get rebuilt in a small local shop if one is available). Now that I think of it, I couldn't tell you whether I replaced it or took it off to clean gunk out of it.

It's not that bad of a job to get the pump off, but I don't think I'd bother if the fuel pump filter is intact and clean. It takes a socket wrench for one, and a box/open wrench for the other. And you will lose skin!

if there's no gunk in the carb fuel filter, I doubt that there is accumulated **** in the pump. So if it works right, and gives enough pressure, probably best to just leave it be.
