Alternator ID and fuel filter question

Post by aevansgatech »

Hey guys, based on this picture, I have a couple of questions

Image

The alternator has a label on it but it's all scratched out. Any idea what brand/Amp alternator I have? ('79)

The second question is most fuel filters I've seen just have an inlet and outlet. Mine has a third branch. Why??

The carburetor you have doesn't have a fuel return port, so a fuel filter with a pressure release valve was installed. This enables the fuel return system to function, which is good, it makes the pump work less and circulates fuel continuously.

The alternator I have no idea, it looks like a stock FIAT (Marelli) one with all the grime that goes with it.

Thanks!

I'll look for a replacement fuel filter with return. I see a few options

According to the shop manual, the stock '79 should be a 55Amp Bosch alternator. Darn, I wish it had a readable label

If its a replacement you are after you have a few upgrade options with more amps. Or are you after keeping it more oiginal?

Most of the Bosch alternators had a couple of places on the back that said "BOSCH" like on the voltage regulator. Put a voltmeter on it. Doesn't matter so much if Bosch or MArelli, you can't buy the Marelli any more.

Good Idea, I'll measure it out.

Doesn't matter too much to me, but I work for Bosch now so I like to put their parts where possible :lol:

So I have another question that's partially visible in the picture.

On the left fenderwall, there is a bracket with a piece clearly missing. Is that where the old emissions stuff went, like a carbon canister or something? There's also a disconnected line which apparently isn't needed anymore down there.
