Re: Fuel Pump Leaking

As I just mentioned; the new pump arrived and this weekend I swapped them out.

I haven't done anything more to the old one as I wanted to do the Postmortem in one shot. One thing I did notice was that it took forever to drain all the gas out of the old pump. I mean really, I wouldn't have thought that it could hold that much gas. That to my inexperienced eye seems to support Howard's idea that there was a hole in the diaphragm.

One thing I did overlook was to see if there was enough room for the Dual Action pump under the A/C Compressor Bracket.

There wasn't.

All in all, I'm going to have to take an inch to an inch and a half "bite" out of the bracket for it to fit. At least I didn't have the system charged up so removing it, while a pain in the neck, lower back etc, wasn't all that big a deal. I'm going to leave it off for now. I'll re-install after I rebuild the new pump with alcohol tolerant parts.

I'll post some pictures of the new pump installed, shortly.

I did briefly start and run the engine. It seemed to run stronger but that may be my imagination. A test drive this afternoon will see if it's really smoother.

We had 29 days above 90 degrees here in Portland and even cooler temps and prolonged periods of not running the wipers usually resulted in my having to turn the wipers on and "help" them move back and forth until they could do it on their own. The wiper motor is a 5 year old Max Merritt bolt on unit.

This time, as soon as I turned on the switch, I had very purposeful wipers - even on dry glass.

More after the test drive,

Jim

I had a similar problem with the 352 cid Packard V-8 fuel pump in my 1956 Studebaker Golden Hawk. Turned out to be leaking around the pivot pin in the for the pump arm. I guess they wear out after a while.


Thank you 56GHMD for that posting. I hadn't considered that the pivot pin could be at fault. When I do the Postmortem I'll be sure to check it out. However normal wear and tear I can understand but mine was 5 years old and had clocked about 3K miles. That seems a little "new" for it to have any problems.

The new pump arrived so this weekend I took the old pump off and put the new one on. I hope that Wednesday I'll have the time to take a look at the old one.

We'll soon see.

The reason I offered my suggestion is the deposits on the pump look like oil, and not gasoline. Gas will evaporate but oil will not.

We will all know more when you do the exam on the removed pump.

(o{}o)


I know and that has bothered me from the start. Which is why I originally though that the gas was being replenished by syphon action from the fuel filter bowl. Curiosity about the oil source is running neck and neck with the gas.

As you say, the exam will hopefully answer all our questions.

An email yesterday said the pump would arrive today but no such luck. Coming from the mid-west would make today's arrival with free shipping really too good to be true.

Thanks again for your help, JW.

Here's a thought: If your engine has crankcase blow-by, it may be exiting from the pump vent and settling on the outside of the pump. Blow-by will escape from the engine at every opening and seal. To check remove the oil filler breather and run the engine. If vapor comes out you have blow-by.

(o{}o)


Thank you again for posting this. I would have never known or thought of checking this.

I ran the engine for about 10 minutes just now and fortunately, there is no anything coming out the oil filler pipe. I thought that would be the case as I've put about 3,000 miles on the car since we got it running and the mesh in the cap looks just as clean as it did after the first time.

Thanks again for your help with this - it is much appreciated as is all the ideas and experiences of everyone else who have contributed to this episode.

I'don't know O_D, it looks pretty sharp and clear on my monitor. And, it looks just like the picture on eBay of the one I bought. Thank you for posting it as it gives me a good idea about the plumbing.

Thanks again -

J.

Actually, I should have mentioned that my main reason for seeking the double action pump is that I was told by my mechanic that whatever oil pump is on the car now, it doesn't have a vacuum segment. So all that powers the wipers at present is the manifold vacuum from the engine.

Absolutely, Howard. I plan to do a complete examination of the old pump and I promise lots of pictures so others may spot what I will probably miss. And you're right about the Vendor. I especially want to know about the last bit as I will have to get a modern rebuild kit for the new pump before I do any driving other than to see how it performs.

And yes about rebuild process. I have not all that fond of memories of trying to assemble the pump in the manner you describe. So it's entirely possible that I'm the one responsible for any trouble I find. Wiser folks than I will hopefully be able to judge what went wrong from the pictures. THIS time, I'm going to get someone to help me put the pumps together. Another set of hands would make the job a lot easier. I thought about using a vise the last time but was afraid of doing more damage than good as I'm sure the pumps were never meant to be squeezed.

Except for the obvious, those are some very nice pictures. Thank you for posting them O_D. The passenger windshield on the unfortunate Packard remind me to move seat belt installation up a few notches on my to do list.

Thank you JW. I learn something from this site every time I post - and even when I don't. I had never heard of that before - which isn't saying much. I will give that a try and report back.

I received an update from eBay this AM stating that the Dual Action Fuel Pump I bought last night will be delivered tomorrow instead of Saturday. So I'm grateful for your post now as if I had put the new pump on and still had THE problem, I would have been lost in space.

I do plan to go with the new pump in the near future as it should give my Patrician an almost bullet proof wiper system. Which in Oregon can be very necessary (although not the last couple of years). I will, however, preserve the AC Single Action Pump so the next caretaker will have the option to return to the OEM style.

More news as it happens.

J.

FLASH!
The third owner of my '55 Patrician and I have become friends and I mentioned I'd like a dual action pump. He is also into old Nashs and Hudsons and he looked up in a book he has for a fuel pump that was used on the 320 Packard V8 that was used in the big Nash and Hudson in '55 & 56

For point of reference it is an AC pump #4293. So I punch the number in and lo and behold there are three NOS AC 4293 pumps currently on eBay. Or rather there was. There are now Two so if anyone wants to grab one of these there is one for $44.95 and and another for $49.95 with free shipping.

Here is the site
http://www.ebay.com/itm/1955-56-Nash-Hudson-V8-AC-NOS-Mechanical-Dual-Action-Fuel-Pump-4293-/171898467220?fits=Year%3A1955%7CMake%3ANash%7CModel%3AAmbassador+Custom%7CSubmodel%3ABase%7CEngine+-+Liter_Display%3A5.2L&hash=item2805f27394&vxp=mtr

Mine arrives here on Saturday so if it does fit, I'll add it to the Parts X-Ref.

Now I know it will need to be rebuilt for the new gas but at least it will be a NOS core.

More later
