Fuel Pump - How old is too old?

[camaronut]

Spoke with a friend of mine who has a 68 327 Camaro yesterday, and he asked me how long I would keep my fuel pump on my 69 SS 350 before I replace it due to age - like preventative maintenance.

To be honest, I wasn't sure what to tell him.  I've had my AC embossed unit on my car since 1994 with no issues (knock on wood).

Now I'm wondering if I should replace it.

Any thoughts / suggestions?

23 years is a pretty good life.  No telling when, but if I were planning any long trips with the car, I'd have a spare in the trunk for piece of mind.  That's what I do.

I'm still running an original AC pump on my Formula I installed in 99.  So it's getting up there.   Raced the car quite a bit for years in PS and it has done such a great job keeping the engine supplied with fuel I've been reluctant to swap it for another just because of age.   However,  I've had a new one in the trunk for the last 5 years or so just in case, lol.     Most of the big cruise nights are a 200 mile round trip for me so I like to be prepared.

I'd say a lot of that answer depends on what gas you've consistently run through it. Pumps give up quicker with ethanol, especially if they sit for long periods of time. Storage surroundings (extremes one way or another) also have an effect on pump diaphragms. I suggest you're pretty lucky to have one last this long.

There are rebuilders out there - we've discussed this previously -
