Hey all, new to the forum as registered user, but i have done much reading! I have a 72 eldo, 500, leather, 75k great shape! I live in the northern burbs of D-town so this car is definitely a joy cruiser from April to October.

I have been slowly going through and trying to make the car a little more mechanically reliable and just run better. In the last month I replaced the distributor, dist. cap, plugs, wires, checked dwell, and timing. once those items were complete it idled 100% better.:yup:

The victory was short lived...as soon as i took the car on the first test run i noticed the "Quadra bog" or so I think! That is where i need some help. I have tinkered a little with the secondary tention screw, but to no avail. everything on the choke side of things seems to be working alright.

In the mean time of getting registered here, and doing some reading on the carb I decided to change the fuel filter thinking that might be the problem (thanks for all of those threads). I did find one of the dirtiest filters i have ever seen!!!:eek: Once everything was back together last night i could not get the car to run. i turned over the engine and it fired right up for about 5 seconds then abruptly cut out. Due to the amount of fuel that came out of the fuel pump when i changed the filter i figured that it might take a while to draw enough fuel to refill the lines/carb. i cranked and cranked but to no avail...

now that i have written a novel here are the questions:
1) will changing the filter require extended cranking to refill the system? i didn't crank for more than 1 to 2 minutes (not straight of course!)
2) how the HECK do you get the fuel filter at the carb out. you can't get a 1" wrench (or any other tool) on the filter retainer in order to turn the 5/8" fuel line nut.
3) will it hurt if i was to re-run the fuel line (in rubber hose) from the pump to the carb and install an inline filter?
4) i will leave the carb questions until i can get the engine to fire. (i will be rebuilding the carb myself during the off season!!! Can't wait to tear into that thing)

thanks guys...frustration ran high last night after a great victory on the ignition items!!! had to go for a run to let off some steam:getaway:

:annoyed: the worst part is that the Woodward Dream Cruise is this Saturday and i have a car that doesn't run!

Do you still have the old filter? See if it had a little rubber check valve. If it didn't and your new one does then it has to be removed from the filter before installation. There are specialty tools available for working on these filters but IMHO it's not worth the bux unless you are in the business. The orignial fuel filter placement design was reliable enough and not a weak spot so I'd leave it.

The only thing i looked at between the new and old filter was dimensions and diameter to make sure if fit. By rubber check valve, you mean a piece of loose rubber on the inlet side of the filter? I will take it back apart and check it out. Now that i say this, i wonder if the filter is in backwards?? (oh boy) when i was loosening the filter (on tighter than heck) the whole assembly fell out. when i put it back together i assume that the open end of the filter would face down (seat on the incoming fuel line)? that's what it looked like in the shop manual.

sorry, forgot one other thing. Would installing a check valve help the car start better from cold. Now it takes 20 seconds of cranking and pumping the gas peddle to get it going. Could be the pump at the carb too, but the whole carb is being rebuilt this winter. Any help on removing the filter at the carb?

Thanks ape man...just made me really ansy to get home and try/look at it again.

It's been so long that I had to go take a look at a filter out in the garage from hell. The rubber gizmo is a gasket and a check valve on some of these filters. If there is just a plain rubber piece in there with a hole in the center then you are OK. If there is a little white valve built into the Black rubber thingy then remove it and put the rubber piece back in. The rubber needs to be there to seal the filter inlet against the carbonator inlet fitting.
Your carbonator might have leaking well plugs which make it lose all the expensoline after sitting around for a while. The WWW is loaded with wonderful insightful inspiring carbonator repair advice which outlines how to fix that.

Wait, the filter that i have been talking about and changed is the one down in the fuel pump. Are we talking about the same one? If so, i am pretty sure that the new filter (pretty small) didn't have a white colored check valve.
I couldn't even get at the filter on the carb. The A/C compressor is in the way.

I guess i need to do a lot more tinkering with all of it, but it definitly is not getting gas. picking up a new pump and (another) filter tonight on my way home.

OK have fun. Change that filter in the carb. Could be your whole problem.

Changing the filter at the carb was my original, original game plan. I JUST CAN'T GET TO THE LITTLE SUCKA! I've even tried using a prybar against the A/C to hold the retaining nut from spinning. any ideas? going to look for "the perfect tool" tonight also.

There are 1" crow'sfoot wrenches designed for this. You can also unbolt the AC compressor and move it out of the way. I always managed to get a regular 1" combination wrench in there.

My 2 cents.

If the fuel system is that dirty, it may be best to drop the tank and clean it. You may wish to flush the fuel lines as well.
I also believe you should probably go ahead and rebuild the carburetor. More than likely some of the debris made it all the way to the needle valve, seat and bowl. This can cause all kinds of problems. I have found it's easiest to cut the fuel line with a tiny tubing cutter and remove the carb. This gives you full access to the inlet nut which sometimes can be rather tight.
Usually it should not take long for the fuel pump to start pumping even with air in the lines. You may have a weak fuel pump and/or possibly a partially clogged pick-up in the tank.

I sure others will offer sound additional advice.

Good luck with this project.

JK & Ape Man -

Thanks for all of the help...here is the tale of the tape. yes the new filter had a check valve in it. Now that i know how the fuel flows through the filter it makes sense to remove it. basically the check is a plastic ring set inside a rubber sleeve that is seated inside the filter. it was extremely easy to pull it out. just pushed in the check with a small screw driver, angled it and eased it out. the rubber retainer can then just be cut away and leave the seal.

The filter did the trick on the fuel issue...but the pump was definitely going. once i had fuel and the car ran it was still bogging on any acceleration. SO, off i was to change the pump. THAT did it!

Thanks for all of your insight...JK i will be rebuilding the carb this winter.
