My spider up me on the side of the road Tuesday night....again. Do these cars ever quit at the house?

Actually, I can't say I didn't know it was coming. My fuel pump had started making a different kind of noise the last few weeks...more like a low pitched growl that varied with engine RPM's as opposed to the high pitched whine of a 'properly working' Bosch pump.

If fact, my car was difficult to start one morning, a problem I attributed to leaving the car outside in the rain due to the fact that we were in the process of moving and my garage was full of boxes. Busy times with the move and work did not allow me the opportunity to investigate.

Anyway, the car dies a mile or so from the house and I push it into a parking space. I'm faced with towing the car home and ordering a new fuel pump. Then it hits me...why am I going to order 'another' Bosch pump when my track record with such is not that stellar?

This would be my third pump...The last time I replace the pump was three years and 8,000 miles ago. Why keep putting the same OEM pump on the car?

I get on the phone and find an aftermarket unit at, don't puke, Autozone for $159. I install the pump after work last night in the parking lot where I had been stranded. Not a bad job...30 minutes tops just reaching under the car (prior fuel pump replacement experience coming in handy). The car fire right up and now runs fine.

The Autozone pump was roughly the same diameter as the bosch and somewhat heavier with a sturdier feel (for what thats worth). The check-valve assembly is visible in the output nozzle. Various pieces and parts were provided for installation on different vehicles. No gotchas for the Alfa install.

I don't know if this pump will perform better or be more reliable than the Bosch unit but I figure it was work a shot. Time will tell but the bar wasn't set too high by the Bosch pump.

A few observations...

1. There is no sound from the pump when your turn the key. No 'Pfsstt' that you hear from a Bosch pump. If fact, after installing the pump last night and not hearing the familiar sound upon turning my key to 'on' prior starting, my first thought was that I had replaced the pump for nothing. Of course when the car started right up, I realized that this pump might have different audio characteristics from the Bosch unit.

2. There is no sound from the pump while the car is running. None at all that you can hear, short of putting your head under the car. Very nice.
My car currenly has less than half a tank of gas, which is when my Bosch pump always got noisier.

A silent pump? Like a real car? how weird! Didn't think that was possible with an Alfa.

New main fuel filter to go on today...to be performed at the house now that I have my car home. The in-tank pump and sock filter are only a few months old.

I'll keep you posted if my experience changes.

Changing the fuel filter is a good thing. I found that as soon as the pump gets noisy it's time to change the filter.

part number please

Could you please provide a further description of the pump such as maker and part number it might be worth the money just to get rid of the noise.
It is always good to have a spare pump anyway. I'll keep watching this thread to see if it lasts.

Just a quick update.
It's been a year since I replaced the main fuel pump on my '84 spider with the Autozone unit mentioned above. The pump has worked flawlessly and has not exhibited any buzzing sound inherent in the Bosch pump.

I have used the car as my daily driver in the last year, logging about 6K miles.

For what it's worth, I would recommend this pump to fellow board members as a very worthwhile alternative to the OEM unit.

I just bought a Chinese main fuel pump on EBay for $79, including shipping, after frying my brand-new Bosch pump. In appearance and fit, it is close to the OEM (though a nice bright blue), and also comes with new nuts and washers for the electrical connectors, which evidently cost far too much for Bosch to include. I'm still trying to get the car started (it's a long story), but I can confirm that the Chinese pump a) works and b) appears to produce adequate pressure (since I can get the engine to run for about 15-25 seconds on the cold-start injector). The pump also has a 1-year warranty from the manufacturer, which does have a web site. Also, the parts seller has a 100 PERCENT FAVORABLE feedback rating on EBay going back to 2003, which is pretty **** difficult to achieve. To find the pump, type the following into the EBay search field: New Electric Fuel Pump:1981-89 Alfa Romeo Spider/Milano. I will try to remember to report back after six months to let people know if the pump still working. Regards, Graham

Be warned: there was a rash of Chinese pumps being sold a while back (last year mabe?) by several vendors on ebay and through Alfa suppliers that would go right to **** in anywhere from a couple weeks to a couple months rather than even close to that 1 year warrantee. (OK, so they'll warrantee it for a year and give you replacements up til that time expires. How many times do you want to change a fuel pump in a year?)

Several vendors in fact stopped selling them and refuse to even consider going the China route ever again. (makes sense as when you sell 10 and 8 come back it doesn't do a lot of good for your business rep)
