Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / November 2005How often do you replace your fuel pump?
I know this one person who work in the city, so he regularly replaces his battery, alternator, and starter every year or so, before they need to be replaced, just so he never breaks down. He says he has to drive through some very dangerous neighborhoods. I am not worried about those, as I have ways to test those components, and you usually get a warning before they fail. But I would like to replace my fuel pump before it fails so I am not stranded or faced to do emergency repairs in the middle of winter or some other inconvenient time. So, how often should you do this? Mine is an original one, and has 191,000 miles on it. It is in the fuel tank, and you need a special GM tool to remove it. And do I really need to drain the fuel before I lower the tank? It only holds 14 gallons max, and I can just drive it until 1or 2 gallons are left before lowering it. Also, how often should you replace your fuel filters and do an ATF change? My GM manual is silent on the fuel filter issue, and recommends an ATF change every 100,000 miles, which seems kind of weird. I last did mine at around 130,000 miles.

I got around 150,000 mi out of the pump in my truck before it failed, with a full 34 gal tank, 1,700 mi from home.

That's incredible! Change it now before its too late. Brushes wear out, commutators wear down, bearings wear out. Yes, you can use up all but 2 gallons of gas. Look in the tank for crud after you pull the module. Change fuel filter at the same time. Buy genuine AC OEM parts, not cheap junk.

I need to replace about 60" worth of line for all three lines (tank to TBI, TBI to tank, and canister to tank). > Brushes wear out, commutators wear down, bearings wear out. > Yes, you can use up all but 2 gallons of gas. > Look in the tank for crud after you pull the module. > Change fuel filter at the same time. > Buy genuine AC OEM parts, not cheap junk. I will! I learned the hard way with my starter. Although for some things, like alternators, I don't care, since PepBoys gives you a lifetime warranty, and they are easy to replace. Julie « Paul » wrote: > Whoa! 191,000 miles on the orig fuel pump!!!? My wife's car's fuel pump lasted until about 215k miles. There's not much to go wrong with them, really. But yeah, 200k is a reasonable time to replace one "on principle." The guy that replaces starters, alternators, etc. though... that's just wasteful. So what if your alternator goes out in a "bad neighborhood?" You turn off the AC, turn off every other extraneous load, and drive to a safe place. > « Paul » wrote: > [quoted text clipped - 8 lines] > You turn off the AC, turn off every other extraneous load, and drive to > a safe place. First off you have to actually understand what an alternator does and how the vehicle doesn't instantly stop when it fails, then you have to have enough sense to be armed if you are regularly driving through bad neighborhoods. Pete C. >« Paul » wrote: > [quoted text clipped - 8 lines] >You turn off the AC, turn off every other extraneous load, and drive to >a safe place. I was able to manage about 300k from my truck - 89 f/s chevy with v6. i ended up taking the bed off the truck to do it. the biggest 2 hassles was getting the trailer hitch off and propping the bed up. an impact wrench with an extension was a life saver, the bolts are slightly tapered like seat mounting bolts. > But I would like to replace my fuel pump before it fails so I am not > stranded or faced to do emergency repairs in the middle of winter or some > other inconvenient time. So, how often should you do this? I've never thought about "pro-active" maintenance - I always replace parts when things go rwong, but this could be a good point. I have a GM car that requires, not only to remove the gas tank, but to drop the rear-axle to drop the tank :( Why GM "engineers" designed that, I'll (and many others) never know. An external pump might be in order!

An external pump might be in order! Damn - I forgot to mention I have ~108,000 miles and have not changed the fuel pump - I dont forsee doing it until it goes bad. Signatureremove MYSHOES to email >Damn - I forgot to mention I have ~108,000 miles and have not >changed the fuel pump - I dont forsee doing it until it goes bad. I have never proactively changed a fuel pump either. But I have been stranded in an intersection in rush hour in Washington DC by a failed fuel pump... and stranded on an airport taxiway where I had to be towed by a follow-me truck.... and had my engine cut out on the downslope of a mountain.... You know, maybe proactive fuel pump replacement isn't such a bad idea either. --scott Signature"C'est un Nagra.

An external pump might be in order! Some more enlightened mfgrs. put a little hatch in the floor so you only have to take out 6-8 screws to access the fuel pump, but sadly this is not universal. nate > > Why GM "engineers" designed that, I'll (and many others) never > > know.

Yea, I dont see GM being "universal" in any regard :) If my Camaro has any "fuel-pump-hatch", it's gonna be behind the rear seats and I SERIOUSLY doubt GM would have spent the money to put one in - heck, they werent smart enough to use an external electric fuel pump!!

Ten minutes with a Sawzall and it could have a fuel pump hatch if you want it to. --scott Signature"C'est un Nagra.

They didn't put one in. And though I don't recommend it, I know one of the guys in our shop who has a Camaro use a body shop style "nibbler" to create his own "hatch". Certainly was a lot easier then lowering the rear axle.

When the day comes to replace the fuel-pump, I'll be cutting out a hatch door too :) Signatureremove MYSHOES to email >>>But I would like to replace my fuel pump before it fails so I am not >>>stranded or faced to do emergency repairs in the middle of winter or some [quoted text clipped - 13 lines] > > nate Yep, wife's 93 Chrysler LH has an access panel in the trunk floor. I changed it's pump with the gas tank completely full. The only vehicle I've had to DROP the tank on was a pickup... and I swear it would have been easier to pull the bed off the frame and get at it that way :-p |
