Oil Pump R&R??

My local NAPA will make up anything you want.  All my external oil hoses are 1/2” ID with AN8 fittings.  Go out back to the hose rack, pick out what’cha want, get them to cut the lengths a little long, then I usually get a box of various AN8 fittings either straight or various bends and head home.  Under the car I can figure out what fittings I want to use and their directions, then measure and mark each hose for length and the orientation of hose and fittings and take everything back to NAPA where they cut and crimp everything.  They take back all of the fittings I didn’t use.  The big rule of thumb is “Don’t expect braided clad hoses to bend much.”  They’re really stiff.

I either use the NAPA store or a shop supply place nearby called “Mechanics Bliss” but they are über old-school and will never have a useful website.  Always interesting to drop in, though, as their tool selection is amazing, but they’ll do hoses exactly as you want them, too.  Big old 4-story warehouse in a seedy part of town and been there since the 1920’s.

Lucky man, Gordon. I lost count of how many times I redid the oil filter lines on the Spyder. Real PIA.

I stopped by my old teachers shop today and got some inspiration. He told me he just uses masking tape on the connectors and a pair of crescent wrenches.

He had a couple of interesting projects.

914-6 GT clone he’s making for the school’s racing program. They’re assembling the motor for it now.

One of the rarities he works on, “Last of the Longhoods” 911S. All original, except for the new dash he’s installing.

@DannyP Al has a point. A lot of cheapo (Chinese?) fittings are undersized. I think what he’s  saying is if a 3/8” won’t fit in an AN-8 (1/2”) you’re screwed. According to the XRP website, many aren’t, especially 45°< fittings.

When I was “doing my own research,” the only thing consistent from one manufacturer to the next was the hose ID. The fitting IDs were all over the place. Doesn’t make much sense to me to put a fitting with a <-8 fitting on an -8 hose. That’s why I went with the more expensive XRP stuff.

^^^THAT^^^                                                                                                                                     The fitting's minimum diameter has to be smaller than the hose id (since part of the fitting will fit in the hose).  I have an old Aeroquip fitting here that I can pass a 3/8" drill bit through the inside of the fitting.  If you check some other brands of fittings you'll find this is not necessarily the case- any smaller and the flow is restricted.

From XRP’s catalogue:

@DannyP Boy, they sure are proud of that aramid fiber hose. I can’t find it any cheaper than $25/foot. And I figure I’ll need 4’. You have a better source?

No. I use Jeg's brand nylon braided, or sometimes Evil Energy(Amazon Chinese stuff). I use the Jeg's for oil and the Chinese stuff for breather lines. No pressure on the breather stuff.

4 feet? That's not enough length to fret over the internal size of the fittings. I believe that only really matters if you route the lines up front to a cooler and back, then you're going 15-20 feet. 4 feet is not enough length for the "smaller" fittings to make much of a difference.

Having said that, both of the suction sides to my dry sump: case to pump, and tank feed to pressure stage feature AN-10 hoses and fittings. Both are bigger than 1/2" i.d. all the way through. All the pressure side and cooler hoses are AN-8.

The engine and trans cooler lines my buddy is putting in his 914-6 GT clone are euro Coline hoses, I swear they’re 1”. They looked like fire hoses.

Engine oil cooler runs up front, trans cooler is in the rear, fed with a NACA duct in the engine cover.

He’s building it to race in a class that gets a time penalty for every non-original bit, hence the hoses/coolers just like the original factory race cars.

Those hoses sure are pretty. He made them up at school where they have a hydraulic crimper.
