How long does a fuel pump usually last? (EFI)

Like the title says. I have 170,000 on my 94 truck. I am wondering who here has had a fuel pump failure and at how many miles. I am just trying to figure out if I should replace mine for piece of mind. I have to drive a lot and I am often many miles from home. The only downside is the cost of the pump I think it is about $300 from toyota. I am not sure if the napa pumps are quality. Thanks in advance!

Purchase my 4runner two years ago, had driving it for seven thousand miles since the purchase and it also have stay in the garage for about a year without starting it, and is currently still running good. Do not know if the previous owner has replace it yet so it still there, I will replace it soon but not that very soon, due to the cost at toyota, price it at 301 here. gL.

while were on the subject: do fuel pumps gradually lose efficiency before they die or do they just die without warning?

the one in my old truck died slowly. It just kept cutting out at slower and slower speeds until I ended up replacing it when it couldn't maintain 45 mph.

usually they have symptoms related to inadequate fuel supply(surging and bucking under high load ) before they quit completely

You can use an oscilloscope and inductive current probe to catch one before they give up

My pump is original with 229K and it's a '93

But it's dying and I'll be replacing it in the next couple days

Still running what it likely the original pump in my '85, 22 years and 280K miles. I do carry a spare on long trips, but the old one is still fine. I also have a fuel pressure gauge so I can see if I ever begin to lose fuel pressure. I think it is usually the motor that goes out or possibly the pump if you run the tank dry. Luckily the pump is shut down as soon as the engine dies (via the Air Flow Meter). I did run my tank dry once and it just stopped, dumped in 5 gals. of gas and it was fine.

should last a lot of miles unless you're one of those people who always runs with almost no gas, and refuses to fill it up. the pump is cooled by gas, and the more gas you have in the tank the better it can be cooled.

Changed fuel pump last weekend.

rustypigeon

I just changed my fuel pump on my 1992 Toyota pickup SR5, V6 155,000. I did because the lines on the bracket, which come out of the tank were rusty and leaking.

I was amazed how easy it was, I dropped the tank and the worst part was getting the filler neck off. I tried taking it off at the gas cap, but almost stripped the screw, so I ended up taking it off at the tank. (Simple hose clamp)

The strainer was a bit old, but the fuel pump looked fine. Since I had it all down I figured I would put a new fuel pump it.

Since that I notice a much smoother acceleration. I also added a new fuel filter since I was under there and covered in Gas.

I have all the part numbers and prices.

I ordered the fuel pump from Conicelli and it was 238.00.

Let me know if you have any questions.

One last thing, anyone doing this, please buy the little clip that is on the bottom of the fuel pump. It's the clip that holds the strain on, you damage the old one getting it off. So re-using it is difficult. I'm sure it's a 100 dollar part from toyota.

OSR, did you have any trouble getting the hoses off from the metal pipes from the braket? The pipes on my braket are also rusty and I am wondering how tough it is going to be to disconnect them. Those bolts that hold the bracket to the tank are also quite rusty.

Those were no problem for me. The threaded fitting was a #[email protected]#$ and if you break it, you're screwed.


You can get Walbro pumps for around $100. I've got a spare stocker (1988) if anyone needs it.. cheap.

I haven't had any problems. One of the number one things to ensure a long fuel pump life is to make sure you don't run out of gas...

I didn't even waste my time. Here is what I did, I bought the bracket, the high pressure flexible house that comes off the bracket and even the line that goes up to the fuel filter. (this line is about 2-3 feet long)

My reasoning, well the line off the bracket was rusty, so was the connection to the high pressure flexible hose. But when I checked I had rust forming at the first bend after the high pressure hose. This is the gas line going from the tank to the fuel filter. So I bought all of it.

When finished I had the bracket connected to the high pressure hose to the fuel line leading to the fuel filter. Hope you follow all of that....

After you drop the tank you can get snake all of that over the frame support and around the emergency brake. lol

All of that cost me 509 bucks. Here is the list;

Bracket (offline so cheaper)
Fuel pump (offline so cheaper)
Fuel Filter (offline so Cheaper)
Fuel Strainer (offline so cheaper)

screws and rubber gasket (dealership)
high pressure hose (dealership)
fuel line to fuel filter (dealership) only 29 bucks I remembered that price.

I can give you part numbers and exact price if need, would have to round up the invoice.

Hope this helps, if I was you reach up and find the high pressure hose, work your way to the front of the truck following that line. When the high pressure hose goes into the fuel line, check that bend mine was pretty rusty there.

Hope this helps.

Osr

ps. This past weekend I put the bracket in the vice and it took me everything I had to remove the high pressure hose from it. I don't think I could do this while it was on the truck. Especially since it was rusty.

I just took a closer look at my hoses. Like you said it would be easier to just buy a new high pressure hose. In my truck (22re) the three hoses from the bracket all attach to about 2ft of flexible hose, then they all connect to metal pipes along the frame until they get to the engine. I think I will buy new flexible hoses along with the bracket. The metal pipes running along the frame are all in great condition. I am not sure what they used for the bracket pipes that causes them to rust so badly.
