flexible oil line

[JohnS48plm]

Does anyone have a part number for the flexible hose that goes between the tubing to the oil gauge? Mine is old and I'd like to replace it. I'd hate to have it blow on the way to North Carolina. John

[david lazarus]

And in my ignorance I replaced mine with copper from engine to gauge:eek: .

I did two loops in the pipe to take up movement and vibration.

Where is this rubber section supposed to be?

I assume it is to give movement somewhere to go?

Look in the phone book for hydraulic hose. Take yours to the place, and they can make a new one for you. I was thinking about doing mine up.

If you can't find a place that sells hydraulic hose, look up a place that repairs commercial construction equipment and or tractors.

Seems like they usually go slowly, and just seep oil as they get porous. Check this thread, several part numbers and other ideas. I got mine from a supplier in Idaho I believe, but can't find the receipt.

Check this hose in the ebay ad of Frank Mitchell MoPar.......9.95 opening bid.

The hydraulic hose shops in my area said they can not reproduce that line due to the type of fittings which are obsolete.

I believe you refer to this line.....

Bob,

Either the hose shop you ask isn't very good at what they do, or they just didn't want to do a small job. If you go to the previous thread on this subject, you'll see I posted part numbers for a flexible brake line hose that works just fine and is available at any parts store. Maybe ask the local hose shop why they can't get the same fittings on the brake line posted.

The original one in my '41 De Soto was one of the ones that didn't "slowly go bad"...

I was on my way home, heading up one of Scranton's "San Franciscan" hills, when all of a sudden, a lot of acrid smoke began bleching from under the hood. I quickly scanned the gauges and saw nothing out of the ordinary: normal oil-pressure, normal temp, etc.

I only had about three blocks to go, so I went for it.

As soon as I parked, I open the trunk and got the fire exinguisher, then opened the hood. A bunch of smoke cleared, but no flames...

There was oil ALL-over the under-hood area. Like someone had sprayed it with used 10W-30 & a Hudson sprayer. I looked things over, trying to find the source of the leak, but couldn't see any obvious point of failure; my oil filter lines are steel and were fine, the metal line to the oil pressure gauge was fine, and so appeared the five-inch flex line.

I decided to start the engine and have another look. Once the engine was idling, I still saw nothing. So, I opened the throttle. That's when a fine stream of oil began to spray from the original flex-hose.

(Okay, it wasn't a total burst/separation, but it shut me down for the day.)

So, I shut it down, let everything cool, then cleaned the engine bay down with Super-Clean and the garden hose.

I removed the OEM hose and went to my local "hose barn". They looked at the OEM piece and said they didn't have that kind of hose or those particular fittings. I asked if they could make-up something that would work, and that they could. The result was some 1/4" rubber hose (Goodyear), and two 3/16" female inverse flare fittings with hose barbs and little yellow collars. The hose just pushed-on; no ferrules or swaging required.

I was out the door in 15 minutes, about $3 lighter. Only a seasoned MoPar nut would know "it's not correct", and it has worked fine for two years...

That NOS hose from Mitchell would be nice for a trailer queen going for an AACA National trophy, nut I'm not sure I'd want to put it on a driver.

While you're at it, what kind of shape is the flexible fuel-line between the frame and the fuel pump in ?

Good luck !

Mine just started weeping oil when I caught it. It probably would have burst if I had not caught it when I did.

I agree with DeSoto Frank, I would not trust any NOS hose on my coupe. NOS stands for New Old Stock Junk when it comes to NOS rubber parts, brake shoe linning or gaskets. Rubber dries out, even in a sealed package after so many years. Then it's not much good at all.

As for the gas line he mentioned. Mine leaked when I bought the car. I just bought a piece of new gas line hose and put it on with two hose clamps. It's been like that for 12 years now and has not leaked. So......you really don't need one that has the fittings on it, of any kind.

[RHDSP15C]

Don't touch that NOS hose that Frank is selling on ebay, the rubber is rotten and the one I bought had been covered with varnish to make it look good.

[JohnS48plm]

I'll try my local hose emporium tomorrow when I go to pick up my master cylinder kit. I also need a steel tube for my oil filter, the one has a pin hole in it. John

The steel line is just a brake line tube.

[De Soto Frank]

My De Soto had original braided flex-lines to the oil filter when I started running it... one of those let loose on a local expressway one evening...

I discovered it by the sudden pounding of rod bearings gone dry. I was lucky to be able to repair it enough to get home that night.

I replaced both braided hoses with 1/4" inverse-flare brake line tubing. It was a little challenging getting the tubes bent w/o kinking them, but they've worked well for the last nine years (25,000 miles).

Come to think of it, I'M still running the original flex line to the fuel pump... guess I'd better heed my own advice and change that one too !

Frank I am also running that original line on my p15. Never could find a source for a new one of those. I didn't worry so much about that one because if it breaks you are stranded but not risking internal engine damage!

Ed, I wouldn't count on not damaging anything if that oil line breaks. It doesn't take long to pump out 4 or 5 quarts of oil when on a freeway with a small leak. Example: Easter Sunday I drove my van when my wife and I visited my brother in law. He only lives about 11 miles from us. No problems going over there. However, we got about half way home on the freeway when the oil light came on. Luckily, there are stores open on Easter Sunday. Was about 10:30 at night. I had to get off the freeway, go into a grocery store to pick up some oil. Bought 3 quarts at first, put it in the engine. Still registered low on the dipstick. So, bought 2 more quarts and dumped it in. Then it was full again and got oil pressure after running the engine a few minutes in the parking lot. Then headed home and we made it without the oil light coming on again. After checking out why I lost my oil I discovered the NEW oil filter with less than about 1,000 miles had split in the seam and had a small leak in it. So.........you can pump that oil out fast with something that small. The oil filter wasn't one of the cheap ones either, it was a name brand. So......if your oil line is just weeping a little, I'd change it to be on the safe side.

Now, if that small gas line should go, that's a different story. The car will simply stop running if it blows. No damage will come of that unless someone lights a match.

[Young Ed]

Norm that was my point exactly. I was talking about his original fuel line. Now that I'm thinking about it maybe I should toss a couple clamps and a chunk of hose in the trunk just in case......

[De Soto Frank]

I think I'll just make a home-brew for the fuel flex; get the appropriate fittings in Weatherhead from Pep Boyz or the like, and some 5/16" rubber fuel line & airplane clamps.

My car is so very far from show-quality that I won't be worried about "non-original style" flex lines for many years !!!

( And I'm getting to old and cranky to deal with things like this on the side of the road ! )

[greg g]

When my flex line collapsed under suction, I replaces it with a loop of the new style fuel line. Just got a piece of steel line of the approximate correct lenght with the proper fittings, cut it at the center with the tubing cutter, off set tien ends about 3/4 inch, made a loop from about 6 to 8 inches of fule line, and clamped the ends of the flex tot he ends of the steel. No leaks no problems. It also makes a easy access point for blowing some compressed air back through the line into the tank if/when needed.

[BobT-47P15]

I got my oil line from these Dodge folks in Canada. Not sure how new or old it is, but still working OK so far. I think they charged me about $15 for it.

I found an oil gauge line from a Mazda truck 1988 to 1993 is very similar to my Plymouth line. The Mazda line is on the firewall near the center.

[Normspeed]

Would the Mazda be metric threads?

I just replaced my oil gauge flexible hose. I don't usually have too much time or gas to burn before work going to a lot of different places to find 1 hose. The one place that I did go to that makes custom hoses did not have the fittings in stock, and I got the feeling that they didn't want to be bothered with such a small hose. I got a brake hose at the local CarQuest store. The CarQuest brake hose number is # SP5772. It was a little pricey, about $16, but for the time and gas $$ saved, I think it was OK. The new hose is a little bit longer, but now has much less of a kink in it than the original hose. I was surprised how easily the fittings came loose with a shot of 'PB Blaster', nothing is usually smooth sailing on this car. The old hose only seemed to have a couple small dry rot cracks in it until I took it off and saw the back side was nearly split thru, just waiting to pop. I took some pics, but "Photobucket" ain't uploading for me?
