?????

Brian, I thought I offered you either a M14 or a M16 fitting to go with the M18 pump fitting, and you asked for the M14.

If you like, I will make one for you. So, its M18 Male seal ring x M16 Male cone?

Should not be hard to machine up. Just have to do a drawing and send it to a machine shop, one might be expensive, but 25 or 50 would not be too bad providing you did not want it out of an exotic alloy.

As Len mentioned above that he could do it.

Here is what I have in stock............



It is used when installing a Bosch 044 Fuel Pump up front at the Fuel Tank. I have just drilled & tapped it to accept a M16 Male Cone fitting as shown..........



so the 044 Fuel Pump can be used in tandem at the rear of the car.

Brian, is this what you need?

I have to say....back in high school (mid '80's) loved the slantnoses, then not so much, but now I've seen a few around here - and this one...this one. So cool. Something about it. Just such a hot rod. Very cool. Keep it up.

Thank you Brandon, I had a clear vision when I went after this car and it is slowly coming around. I'm lovin' it!

Let me take some pictures of the fittings I have and you'll see what I am after. I really did not want to have a custom fitting made but if that's what must be done so be it.

Here's what we are working with. The OEM fitting is M14 male to M16 female conical. Bosch -044 has a female M18 outlet. So we need to get from a female M18 to a female M16 conical in ONE step intead of two.


Here is the daisy chain of adapters: M18/M16, M16/M14, M14/M16

Hi Brian,
You can shorten the pressure/outlet side about 1" by removing the gold cad plated spacer in between the pump outlet and the check valve/banjo fitting. That spacer is not needed and the check valve will thread into the pump outlet threads without it.
That helps alot to shorten the pump when you put an 044 in the front.

On the suction/inlet side there must be a way to do it with one less adaptor. But it may still fit with the stack you have. The 044 pump body is a little longer than the stock pump too.

I think Turbokraft has installed 044 pumps in the back of 930's and David Cole has done it on his car so maybe they know of a shorter length suction side adaptor(s).

Thanks for that tip Jim, I haven't gotten that far yet.

Yes TK is having these fittings machined but that will take weeks ...

Yes Cole has a -044 in back but he changed out all the fuel lines to AN fittings.

I think this is it Len! If that brass fitting is a 18M to 16M cone we are golden!

I havn't looked at the rear pump in a while and having thought about it some more I don't think the rear pump uses the check valve. No reason to since the front pump has one on it.
I think the rear pump has a banjo bolt there instead so I don't know if you'll need the spacer with that or not.

and yeah, I didn't know Cole changed the lines and used AN fittings there.

Hi Brian, here's another view of this fitting............



Yes, this adapter is a M18 seal ring to the pump with M16 Male cone. This can also be done by drilling & tapping to accept a 1/4 MPT x M16 male Cone adapter. Don't have a photo of this but it should work the same.

Shall I send you the one in the photo? Do you need hose as well?

Bring it on Len! I'll send you back the other fittings.
All the hoses in my car are OEM and will stay for now. One thing at a time ...

On a bright note this weekend was gorgeous, 50 mornings and 75 afternoons with bright sun and turning leaves. Great turbo weather. Got the ghost out both days for a short run through the hills. Car ran well, boost is strong for a stocker! Once I finish getting this fuel system refreshed she'll go to the dyno for a baseline run then it's mod time baby! No 915 holding this bad-boy back!

Weather looks like it's degrading. Sent you and email Miguel.
If Len's fitting arrives today I know what I'll be doing ...

They're in the lathe right now. :-)
One piece, billet aluminum, correct concave ball seat for the M16 side to connect to the stock 1978-89 fuel lines. They'll be hard anodized next week, and available to ship a few days later.

When installing the -044 pump, don't forget the pump uses larger electrical terminals so you have to change out the ring connectors on your harness for ones 1mm larger.

Concerning noise -- install it in the 964/965/993 rubber housing:
#965 356 391 01 = rubber housing, ~$31
#965 356 389 00 = rubber cap, ~$9
Then change out the 60-80mm mounting clamp for a larger 80-100mm clamp that fits around the rubber.

New (?) Running Issue

Two steps forward and one step backwards, that is the credo for restorations isn't it.
A new (?) issue surfaced on Friday. My son has been wanting me to take him to school (he is a sophmore in HS) in the slant so his buddies can see the car. I've been putting it off with all the fuel system issues leaving me less than confident driving the 35 mile round trip in rush hour traffic. Well I've adjusted the WUR to compensate for the weak pumps and the car has been running pretty good so I thought we'd go for it. Fired 'er up on the chilly morning and off we went. Car ran flawless all the way to the school and about 1/2 way home. On the final stretch I fealt a slight hesitation that progressively worsened. At steady cruise it would periodically buck like you were switching the engine off and quickly back on. When I rolled up to stoplights it would idle perfectly. Pull away and the hesitations start again. I coasted down a mountain with the tranny out of gear and the idle was rock steady. Put it back in gear and the bucking returned. When I got near home I decided to boost it and see what would happen. Power was strong as usual but the bucking became expectidly violent when it occured. When I let off after boosting through 2nd gear the bucking was full blown bad and often. Nursed it home and put 'er away. This morning I put an LM1 on it and fired up. Started perfect and instanly, idled perfect. OK lets go for a ride. Ran perfectly for a couple minutes then very subtly the hesitations returned. Once fully warm the bucking began. Boosted it and the bucking became horrible.
So this is a repeatable failure of some sort. Here's what we have observed:
> No bucking at idle cold or warm.
> Bucking begins as engine warms and progressively gets worse.
> AFRs are good. Does not run lean at any point in the range.
> Power is good.
> Bucking is like you are cutting off the key quickly. Frequency is every 10 or so seconds during onset and every second to several times a second after boosting.

Have any of you seen these type of symptoms? Would be great to have my suspicions validated or disproven. This is a tech forum so no better place than to solve it here and post results.
Thanks!

Sounds like over boost or ignition being pulled.

Brian,
Those pumps may be drawing more current through the marginally adequate red relays. You may have to rewire the pump circuits with heavier gauge wire and higher current handling relays if you go to the 044's.

As a contact in the relay crystallizes over time, the contacts experience a voltage drop over the contacts resulting in less than adequate current to the pumps. As the contacts heat up, the problem becomes even more dramatic. As a short term experiment, put a pair of blacks in the pump relay sockets and check if the situation changes.

Given fuel pressure and AFR are good and the condition starts as the engine warms, sound like a classic coil issue to me.

Good suggestions!

> The -044 pump has not yet been installed so there should be no extra current draw (yet). I'll sure keep that in mind when the new pump is installed!

> Ignition or fuel seem to be most likely but I don't want to rule anything out as this car is old and neglected. All o-rings have been replaced and the BOV rebuilt. The symptoms I am seeing now are similar to the jerkiness experienced when the BOV was sticking. Difference is this time the jerkiness occurs when off-boost and there is no loss of boost pressure.

> Overboost switch is easy enough to test, I'll pull that plug and the air meter plug and see what happens. Will try to do that today and report results. The LM1 will remain installed until this problem is fixed so we can monitor the fuel system.

> Coil was tested when I first got the car as well, but again that was then and this is now. I have a spare coil and will plug it in. Probably can't get to that today.

> I did pop the hood and feel the relays when the car was warm and the relays were warm to the touch but not hot. When I first got the car I pulled all the relays and tested them, all were good. Everything works until it breaks so those tests are meaningless now. I have a new spare red relay that I keep in the car's tool kit, will try that as well and report.

I just went through what sounds like the exact same issue, with exactly the same symptoms. It finally lead to a no start. Took the car back to the shop (in the light), and noticed the coil had slipped down in the clamp and was grounding out on my intake housing. Moved it back up and ran like a champ again.
