Sajeev,

My ’99 Accord 5speed with 200k on the clock needs a new gas tank. The fuel pump is inside the gas tank. Should I get a new fuel pump with that gas tank? Changing the tank will cost about $600; including a fuel pump will add $300. I’m planning to keep this car another year and a half to two years, at which point it will have about 230k.

(I will replace it with whatever version of the Toyota FT86 reaches our shores provided the car does well repair-wise in its first year, and provided I like it as much as Bertel’s review suggested I would.)

PS: can you get this one up ASAP? I need to get the tank before I go on a road trip Dec. 24.

Sajeev Answers:

$300 for a fuel pump? Please check the prices on Rockauto.com and verify your shop isn’t marking up their parts costs.

That said, I don’t know if the pump needs to be replaced, there’s a good chance it will last 2 years. Even if it fails, you don’t need to drop the tank to install a new one. Tough call. A fuel pump should be more like $100-150 and labor should be nearly nothing considering the tank is dropped.

David replies:

Sajeev,

I suspect the $300 was for an OEM fuel pump. On Rockauto, they start at around $30, and a number of them are 100 and change. I guess one thing that makes me nervous is the thought of switching from my original to a non-OEM. I mean, it wouldn’t completely surprise me if the original went for a few more years and a non-OEM quit after a few years.

Sajeev Concludes:

I suspect that $300 was for the complete fuel pump assembly. Wait no, I never suspect that. As a tireless cynic when it comes to random mechanics giving quotes to my readers, I always go for the worst. That said, Rockauto sells the Denso fuel pump (OE part) for $118.00…and Denso stuff ain’t no joke, this is what you need.

Would a nameless, faceless shop charge over 200% markup for the same part you can buy online? Perhaps. It wouldn’t be the first time, son! Wrap up: there’s no wrong answer, replace or no. The only problem is the cost of said part.

Send your queries to sajeev@thetruthaboutcars.com . Spare no details and ask for a speedy resolution if you’re in a hurry.

FWIW - I have a 99 i4 5spd as well. It's got 260k on the original pump. since you can clearly see where the access is, replacing the pump in it is not really a lot of labor later on down the line. I could do it in a hour or so. I say just roll with the stock pump until it has to be replaced.

@afuller: I don't see anything wrong with your retail markup. What's wrong is the outrageous Honda price on the tank to start with. Rockauto has a tank for a similar year Chevy for 79 bucks.

Analoggrotto I don't see a red car here, how blazing stupid are you people?
Redapple2 Love the wheels
Redapple2 Good luck to them. They used to make great cars. 510. 240Z, Sentra SE-R. Maxima. Frontier.
Joe65688619 Under Ghosn they went through the same short-term bottom-line thinking that GM did in the 80s/90s, and they have not recovered say, to their heyday in the 50s and 60s in terms of market share and innovation. Poor design decisions (a CVT in their front-wheel drive "4-Door Sports Car", model overlap in a poorly performing segment (they never needed the Altima AND the Maxima...what they needed was one vehicle with different drivetrain, including hybrid, to compete with the Accord/Camry, and decontenting their vehicles: My 2012 QX56 (I know, not a Nissan, but the same holds for the Armada) had power rear windows in the cargo area that could vent, a glass hatch on the back door that could be opened separate from the whole liftgate (in such a tall vehicle, kinda essential if you have it in a garage and want to load the trunk without having to open the garage door to make room for the lift gate), a nice driver's side folding armrest, and a few other quality-of-life details absent from my 2018 QX80. In a competitive market this attention to detai is can be the differentiator that sell cars. Now they are caught in the middle of the market, competing more with Hyundai and Kia and selling discounted vehicles near the same price points, but losing money on them. They invested also invested a lot in niche platforms. The Leaf was one of the first full EVs, but never really evolved. They misjudged the market - luxury EVs are selling, small budget models not so much. Variable compression engines offering little in terms of real-world power or tech, let a lot of complexity that is leading to higher failure rates. Aside from the Z and GT-R (low volume models), not much forced induction (whether your a fan or not, look at what Honda did with the CR-V and Acura RDX - same chassis, slap a turbo on it, make it nicer inside, and now you can sell it as a semi-premium brand with higher markup). That said, I do believe they retain the technical and engineering capability to do far better. About time management realized they need to make smarter investments and understand their markets better.
