Well, I put fuel into my 914 tonight and tried to pressurize the system. My car quickly started to pee on the floor under the fuel pump. Soooo, I can see no way that I can be ready for Hershey with my car as I need a CIS fuel injection pump for a 74 911 2.7 engine.

Anyone know of a cross over part?



I'm running a Volvo pump and accumulator... Works on my CIS. 4.7

Can you say cheap salvage parts?

(IMG:style_emoticons/default/agree.gif) Most any CIS pump will work... along with Volvo lots of VW + Audi's had CIS.... shouldn't be to hard to find one in the boneyard... and new pumps for many of these can be had for less than $200

Ok Mike.....Python Injection is in Stanton, CA. I was there yesterday. I can check and see what they get for the pump if you wish.

There is a suitable replacement pump, not an OEM. It is way cheaper. Unfortuneately, I don't have the name of it at work. I'll post it when I get home, or if I remember

ejm,
that is what I was thinking, but my concerns are:
1. what pressure can I get/do I need?
2. What flow rate is necessary?

If I could match these criteria I would not worry. The big beef is that I doubt I will get a part by tonight or Fri. The junk yards here SUCK. I miss CA.

Rick,
What pressure/flow does your pump run, and what does your accumulator keep the pressure at?

sixnotfour,
True, but the 77 had a two pump system with a front and a rear. If the rear meets the parameteres that I need for my system then I would likely get one of those as thery are much cheaper and easier. An ebay guy told me that the 77 style is the right pump, but I am sure there is no returns and he may just want a sale.

SLITS,
I searched python and found them to only have the later style 77 type. No '74 type. If you find something, please let me know and thanks.

nein14,
I'll look into them.

I have my friend from class with me today that is into cars and is a local. Maybe she can point me to a parts yard.

What models/years should I be looking at for a surrogate pump?

Does it matter if the donor car has a 4 or 6 cylinder engine? I figure equal displacement engines will have equal pressure volume pumps.


Mikey just had to get a /6......

Pressure is determined by the regulator on the CIS, not the pump.

I agree that almost any CIS pump should work.

(IMG:style_emoticons/default/agree.gif) and the accumulator holds residual pressure on the system when the engine is off. This is needed to prevent the fuel from boiling in the lines and causing a hard start hot problem.

That all makes sense. I guess the difference between the $500 pump and the $150 pump is the P word and the mounting location.

"I agree that almost any CIS pump should work."

Joe, I am only afraid that I will not get one of the "almost any" ones. I'll see about hitting a yard or two. The yards out here need you to know tha model and year and then pull it for you. PITA. A new one will take a week to get here and I have definetly given up on rushing. Gonna be driving the Benz........I guess I will have to sit in a parking spot with my seat holding a 914club sign for the Hershey meet.

Anyone know what PSI range I am looking for? There are many after market that are inexpensive and would actually be easy to mount, but I need to know what range I am looking for.

Mike,

I have a FI pump out of a 2.0 /4. I know that it'll put out well over 100 psi. Joe sharp can verify it. I just don't know if it has the volume.

You can have it if you think it'll work.

Good question, and thanks. I found that Bosch 0 580 464 007 looks exactly the same and is for a 69-75 Volvo 140. No idea of the pressure and flow. Or if the 140 was K jet or not. I'll be looking.

If I could find out what pressure range I am looking for then I would have an easier time.

I may have a /4 pump in a box somewhere, but I am concerned about volume as well. I'll let you know.
Thanks again.

CIS runs around 75psi, depending on the exact application. Once again, the pressure is determined by the regulator, not the pump. Yes, the pump has to be compatible with the pressure and flow requirements. I firmly believe a CIS pump from any '80s Golf/Jetta/Scirocco would work on a '74 2.7.

I will probably confirm this next month on the TurtleGirl installation ('77 2.7 w/CIS).

A /4 pump will not work. That system runs in the 30s psi and that pump was not designed to handle the high pressure a CIS regulator would attempt to create.

Well, I was just looking around at some systems and they run cis at 48-60psi...or that is just when the injectors open. Volvo is looking like a good donor. I'll check 80's VWs too. Thanks.

This one WILL work.

You can't have it tomorrow, but it's new.

Yup, that is one that i have been coming across regularly for many models. The one end is funky and in need of replacing to work with my system. Ebay has a load. My fule pump has a wierd Bosch number on it 158025499. I can't find a match anyware. The one for the volvo is on ebay and is at $12 new.

http://cgi.ebay.com/ebaymotors/Bosch-elect...056720557QQrdZ1

Not sure if I should jump on this one as it is the same looking pump as the OE. The Bosch p/n that I got off of another site for Volvo, Porsche, and Renault is 0 580 464 069. I couldn't even find a listing for 007 on the site.

Any info? I'll be getting one, just trying to get some info and make an informed decision.

The 'funky end' is a check valve. You just need the banjo fitting and cap that goes on it. They are not hard to find.

Auction says its for a '74 .... seems to me Volvo ran a version of D-jet back then so that pump would be for a lower pressure system
