1978 Cadillac Eldorado Fuel Pump R&R

[dennisspeaks]

I am suspecting that my fuel pump is going, the car has little power and is sputtering when I press on the gas.  How difficult is it to change one out on these, I have not been able to find any youtube videos on this process.

Any brands to stay away from?

Thanks,

Dennis

A bad pump could cause those symptoms but there is about a dozen other things that could also cause it.   Pump isn't that expensive or difficult so if it doesn't look like its been recently replaced it may not be the worst idea to replace it. 

Its not too bad a job.  The worst part is sometimes the fitting for the hard steel line really doesn't want to come out and there isn't a lot of room to get flare wrenches on it can good leverage.   I have had to cut the line and get it on the bench to get em out then use a piece of hose to splice it back together.   

I get confused between these and the Olds which is a very similar pump just flipped upside down and on the other side of the engine.  One of the bolts gets blocked by the body of the pump so you have to take forever with a open end wrench or I think you can squeeze something like a gear wrench in there.   I find it easier to get at it from below.  You have to be below to deal with the lines anyway.

I replaced my fuel pump on my 78 Biarritz.
It was easy and straight forward.
One additional thing.
There is a section of the Cadillac shop manual regarding suspected fuel delivery
issues you have.
It states that while you have the fuel line from tank disconnected, that you carefully set your air compressor
output to 5-8 lbs. of pressure , attach a blow gun, and gently back blow the line to the tank until your
hear bubbling and gurgling.  This is meant to gently blow away any collected debris from the mesh pick up sock in the tank.

Hope this helps.
