The fuel pump in an F-body is no more likely to fail than in any other car, IMO.

Since your car was bought used there's really no way to know how often the fuel filter was replaced over the life of the pump.

I find that many people fail to replace these filters often enough, and IMO that explains why some people have fuel pump failure at ~60K miles while many can make it over 100K.

mine went out like a SOB with 40k miles...the 98s and 99s had a gm statement on some of them that they were bad from the factory...and ive seen several 99s go out...

lets say you know 36 people "dozens" out of those 36, 1 fails....put that on a national scale....i understand its not like a window motor....but i took the thread as, "what fails in a LS1 motor"....

Alright lets take the 1 in 36 number then, that's 2.7%. In reality that's probably how many have failed on a national scale, ~5% I'd say. Hardly a comon issue, IMO.

you cant minize every problem with the motor....i mean with the car there are several things....but the motor...your looking at belt tensioner, oil pump, rod bolts, and fuel pump to name a few.....

What's the fuel pump have to do with the motor? That's fuel system specific. Anyway, what makes you think the fuel pumps are weak? If you keep the filter changed they usually last a pretty long time from what I've seen.

And rod bolts aren't a common problem on stock motors. That's only an issue when you start spinning the motor to higher rpms than the stock rev limiter.

if you purchase a 2000 or earlier ls1 its a good idea to replace the oil pump.they have a tendancy to just lose oil pressure.you can research this.in my opinion this is the most impressive engine gm has ever released.as for mileage mine has 156k still runs very strong.but this was all highway miles.good luck with what ever you do.

I'm agreeing with RPM WS6. Change the fuel filter often. At least once a year no matter the miles. Oil pumps, same thing. I use Mobile 1 and change it every time the seasons change. 4 times a year. It's more expensive but you will avoid a lot of problems by keeping fuel and oil systems clean. And mileage isn't as important as 'change intervals".

I don't need to research this. I've owned and worked on many of these cars for the last 8+ years, and been around the LS1 community for as long as the motor has been put into F-bodies. It is not a common issue, and it's not worth replacing the pump unless you are already in there doing a cam swap, IMO. Only a very small percentage of '00 and earlier LS1s have had oil pumps fail, and when they do fail, it's usually at a low mileage.

If you don't run it below atleast 1/4 tank of gas, and change the fuel filter about every 30k the fule pump should never die. So thats not a problem, you just have to get in the habit of not running it low on fuel.

I agree. Why changing something working perfectly well?? I too dont see this to be a common issue. Ive never seem a thread regarding this in a very looong time here at LS1TECH.com......
