Fuel pump

[paris]

Hello does anyone know if there is a difference between fuel pumps for a L-jetronic CIS car an AFC INJECTION? The fuel pump which went bad is a bosch 0580 254 980 which they do not make any more any input would be great. Thanks, Steve

You can find the replacement number at Bosch-Fuel-Pumps-Cross-Referrance-Guide

If you post your car's year and origin (ROW, Japan, etc) someone could make a recommendation.

What difference does it make what he pays for it? If you want the correct fuel pump, he is willing to sell it to you for $240.

Cost of Parts is something that forum members / Guests are interested in cost of parts .
Our Host " Pelican " Sells Parts. Perhaps the Moderator of this forum can better explain this to you .
As a member I am certainly interested in the cost of parts and the lowest cost of Quality parts .
I am not selling Parts but when I need parts I search for them and the best price .

Yes, Pelican sells parts. And 928 Int'l sells parts. And 928 Specialist sells parts. And 928 Motorsports sells parts. And 928sRus sells parts. Concievably, they all would pay the same wholesale price for the same part. What they pay has only a small part to do with what you, as a retail customer, would pay. Each company has a return on investment percentage that is the basis for their pricing.

Pelican doesn't specialize in 928 parts, they specialize in Porsche parts. What is a moderator going to "explain" to me about this fact?

So back to the original question, what difference does it make what he pays for it?
You are not paying wholesale as a retail customer and if you think you are paying wholesale, you are deluding yourself.

The real question should actually be: what price do I have to pay to get the correct fuel pump for my car? You can look the price up right here on the Pelican website if you know which fuel pump is correct for your situation.

Roger just made it easier for you to compare.

I wish you luck and all the best.

I'm not sure I understand your question. Roger is major parts seller and buys in quantity from sources at prices unavailable to end users, his costs are not public information any more or less than any other vendors costs are.

Buying outside the group of knowledgeable 928 parts vendors ALWAYS carries a greater risk of getting the wrong part regardless of the part number you or they supply related to the part. Chinese knockoff parts routinely use Bosch and other name brand part numbers.

ding ding. exactly. CIS is K-Jet. Buy from the board sponsor or known 928 parts vendors mentioned. Also, you might have an in-tank pump as well. My CIS did.

I would not be looking for the "best price" but I would be looking for the "right part" at a "good price". Often the "best price" is not the right part. I personally prefer to buy from 928'srus, namely Roger, as he has a vast knowledge of 928's, shares it freely, and is more than happy to answer all my 928 questions. I have also bought off Pelican, 928 International, and all of the other remaining so called "big 4" of the 928 vendors. Far better luck with any or all of them over eBay buys, the local PepBoys, the Porsche dealership down the road, or Chinese made knock offs..... might be a bit more expensive to start with but how much do you really save when the part doesn't fit quite right, or it dies in xx days, or it doesn't work at all?

[Danglerb]

Roger may not always have the best price, but he is NEVER far from it, so anybody claiming to be selling something 10% or more less than Rogers price should be seen as a red flag, not a good deal. Same goes for 928Intl as many here would routinely call both places, so they never vary by much.

Ya Most parts have Huge mark up this I learned long ago from a person I know who became a major parts vender . Purists most often insist on brand new factory Parts .
A Rebuilt Water Pump is a Great Example . What is it any way , has a factory casting , a aftermarket impeller or perhaps not . some bearings and a seal . Point is that a rebuild pump with the Right Seal and the right Impeller / Bearings in it will do exactly the same job . they come in all forms / Good ones and bad ones . So You Need a Good one not a bad one the word is quality. With a Rebuilt pump you want one with a Plastic Impeller not metal as original or you could damage the Block . I am not asking any Questions but making statements . some people like a book and some do not Its simple .
Poured some Transmission Sealer on a leaking water pump Seal for a few days and it stopped leaking for another 10 years on a diesel Truck I owned , never did change that pump . Bought new factory parts that failed as well as Rebuilt parts that failed . Some work and some don't . Heard about a quality Part I need at a good Low price that's the part I want

When a 928 water pump fails it takes out the timing belt, or the block if the metal impeller migrates.

Castings can only be reliably rebuilt so many times, and the rebuilding industry basically killed itself going cheaper to compete with Chinese knockoff parts.

As of a couple years ago Porsche NA had one of the highest parts markup, 40% for the benefit of passing through its warehouse. On many parts the only option is used vs dealer prices.

One of the worst parts of 928 ownership are the cars where the previous owner saved $10 on the wrong part, or paid hundreds more using the wrong mechanic.

Well... I have little control over my parts costs, but Thank God my mechanic works dirt cheap!

Hello, well I got back on my 928 after finding the correct fuel pump brand new in the box at a pawn shop for 20 bucks what a deal. After installing it in my 1980 euro 4.7 with CIS I still have the same problem with my fuel pressures as I did with the cheap aftermarket pump I bought on ebay. I got my CIS gauges out and hooked them up and my system pressure and control pressure are the same at a little over 5 bars on both. I have rebuilt the fuel distributor and looked it over good, plunger moves good, could not see any problems with it other than bad orings. Has anyone ever seen this problem? Could the WUR cause this? Any help would be great, thanks, Steve

[Danglerb]

I don't know CIS, but those who do may want a bit more detail on what exactly you measured and how.

[paris]

The engine will not start because there is to much control pressure, I put my CIS gauges one hose going to the WUR the other hose which screws to the WUR coming from the fuel distributor, which measures control pressure and system pressure, when moving the lever there should be a large difference in fuel pressure but there is not, both control and system pressure are the same at a little over 5 bars. I have done some reading online about this problem and every thing points to the WUR. I plan on taking the unit off and take it apart and see if the spring is broke or the heated strip is ok. I also read in this one guys artical that there is a passage way in the WUR which could be blocked. I am hoping I find a problem with this unit, because I have checked everything I can think of, I also took the return line off and let it run with the pump relay bridged and the fuel runs out as it should and the line going back to the tank is free of clogs. Thanks, Steve
