Looking for an Electric Fuel Pump - Need Advice

[Crazy Harry]

A friend of mine is looking for a particular model of Bosch electric fuel pump for his '71 Alpha ? The label on the fuel pump is:

Bosch
0580464005
12V427

I've done some basic internet searches and found little information. One hit suggests this pump may have been replaced by a Bosch 61405. Another link indicates this pump may have been used in "all" models of Opel in 1975 with the 1.9 engine (hence my posting this question here).

Does anyone have any experience to share? Any suggestions where one might find a reasonably priced replacement?

Thanks,

Harold.

Try the Bosch's automotive e-catalog at:

AA Extr@Net

After you choose language, at the top you will see an "Article Direct Search". tab. Select that. Put the 10 digit code you have at the search-engine, click search and it will come up with the part. Clicking then on the part, there will be an "Engine Links", and a "Vehicle Links" option, that will get you to see where it is used. VERY handy for obtaining identical parts from other-brand dealers...

The "Article Information" link, which is available together with the pre-mentioned links rarely gives any useful information, but you might want to check it out.

I put your code in that engine, and saw that it was used in Fuel Injected cars (High pressure). It was used in several Opels, the Manta A 1.9 GT/E is one of them. It will not be suitable for a carb application...

A friend of mine is looking for a particular model of Bosch electric fuel pump for his '71 Alpha

You might mean "Alfa"

The pump he's looking for might be this one:

eBay Motors: New In Line Fuel Pump BMW Opel Alfa Romeo Fiat Renault (item 190129189334 end time Jul-14-07 20:33:58 PDT)

It's for Alfa Romeo, BMW, Citroen, Fiat, Opel, Renault, etc. in line types (fuel injection ONLY)
This type can replace the following Bosch model numbers : #0580-464-014 #0580-464-013 #0580-464-016 #0580-464-019 #0580-464-020 #0580-464-023 #0580-464-032 #0580-464-033 #0580-464-038 #0580-464-070

From my own searches, this is about the best price I have seen at $79 USD

Harold, is that for a Spica injected engine? These are actually low pressure pumps. There is info out there on using other pumps. I use a Ford P/U pump on my alfa, not too bad to set up, reliable, Much cheaper and easy to get.

That is a VERY good link. Interesting, as they say to use the "L-Jetronic" pump (which is what the '75 Opel has) and just modify the Spica outlet restrictor port by making it smaller (from 3/32" to 1/16"), to ensure the supply pressure stays within design (15 to 18 psi). I would have thought that the L-Jetronic pump, designed to run at 42 +/- psi, would cause problems, but it is the recommended replacement pump for the Spica fuel injection system. Apparently the L-Jet pump has a bit lower volumetric output, so the port has to be decreased in size to maintain the recommended pressure. I wonder why they didn't just use a pressure regulator like the L-Jet system does?

Thanks for all the great input so far.

A few points of clarification: The Alfa was originally injected but has been converted to carburetted (twin Webers I believe). My friend has a Carter replacement but is reluctant to do major mods to get it to fit that's why he was asking about the Bosch unit.

Any further suggestions would be appreciated.

Thanks,

Harold.

The Carter pump is one of the better electric fuel pumps, and well suited for a Weber carb application. The Bosch pump is NOT suitable for the Webers, as they need a maximum of 4 psi, and even the Spica pump is designed for up to 20 psi. The L-Jetronic pump is designed for 42 psi. Any EFI pump will cause major flooding on a Weber carb.
