Looks like the Denso direct replacement (957-003) NLA. Anyone tried other brands like Delphi or TYC?

I am not averse to splurging on a new OEM unit but 2 years service life is very unsatisfactory

If Denso is NLA, I would get TYC. They’re at least an OEM parts supplier for Toyota, despite not being the pump supplier.

I'd find an equivalent denso from another toyota.
It's not a big deal to put any pump in there and fab anything you need. But you need the top plate of the assembly.
Most modern or of the same era toyota pumps are going to be fine to adapt to the top plate.
Just some line and wire work probably. The top pump connector is going to be model specific.

I'd go backwards and use a non vvti or anything with the close to same dimensions.

I wouldn't have a problem with a Bosch pump either. Anything that fits!

That’s a good point - I’d bet you could make a 1st Gen Sequoia/4th Gen 4Runner pump work.

Excellent points, I ended up ordering this Bosch unit from eBay. Not sure if it is genuine but at $50 it is worth a shot

1. The pump is showing as open circuit (no resistance between terminal 4 and 5)!

Do you mean no resistance or infinite resistance? No resistance can be interpreted as short circuit.

I will edit my post to correct it, I was infact getting infinite resistance. Thanks for pointing it out

My Denso direct pump continues to live in the drawer in the back at 215k. My OEM keeps trucking. But it was super cheap so I'd get two and keep one in the truck. They don't take up much room as you know.

I put a new OEM alternator in (New, from the dealership) and I already think the rectifier is failing. No idea what's up with Toyota parts lately. Only saving grace is when it craps out within the first year.

I do the same. Carry a spare. The pump was replaced before I bought the truck so I assume it will go out eventually.

@OwnerCS I know you have posted before on tip to identify whether a part is original or fake. What should I look for on a Bosch part in bulk packing, like this one: Fuel Pump and Strainer BOSCH for Toyota Sequoia Tundra,Land Cruiser Lexus BULK | eBay - https://www.ebay.com/itm/143825875657

If Denso is NLA, I would get TYC. They’re at least an OEM parts supplier for Toyota, despite not being the pump supplier.

@JunkCrzr89 The TYC pump is only $15 on rock auto. While I don't equate price with quality (case in point my $275 OEM pump ) but I do wonder why TYC is so much cheaper than even the Chinese brands!

I'm most familiar with OEM and codes. First time to see a Bosch part. I will say that the box does not look freshly printed like a counterfeit.

The Bosch pump appeared to be genuine but the plug was slightly bigger. I could easily modified the harness to use the plug that was provided with the pump but decided to just buy the OEM pump at $333 and install. Happy to report that the truck fired right up with the new pump!

Just out of curiosity what is your opinion on why the OE failed? Think maybe it was electrical or perhaps the recent rash of poor quality fuel damaging the pump itself?

 

[ClassyJalopy]

That is what's most mind boggling. The pump failed suddenly, with no prior signs! No hesitations, no RPM fluctuation, nothing. It must be the underpants gnomes!

Underpants Gnomes are a very real and super serious concern often disregarded or dismissed as wholly impossible. Sometimes, due to their mischief things just do fail despite marginally decent engineering. That blows, broski. Hopefully, new OE allows you to forget about it this time.

• Added these ditch lights but haven't wired them up yet - bracket is from Ronin Metal works
• Switched the corners to clear. These are LC corners running OEM 3 plug harness. I want to eventually add turn signals to them as well
• Replaced the fuel filter (to match my shiny new fuel pump)
• Replaced gas struts on the ARB rear swingouts. Was surprise to see O'reilly had US Made Stabilus struts. Those struts were OEM for ARB and cost about $50 a pop if you get them from an ARB dealer. I paid only $19 per pop.

After returning from a 500 miles trip to Badlands off road park, I took care of the following maintenance items:

• Engine oil: 5w-30 high mileage synthetic with Mobil M1-209A high capacity oil filter
• Rear Diff: valvoline flex fill sae 75w-90
• Transfer Case: valvoline flex fill sae 75w-90
• Grease rear driveshaft - still need to lube the front driveshaft

Trip to the Badlands off road par in Attica, IN was a hoot! @PrinceJabar and I spent whole Saturday riding different trails and features. No body or mechanical damage, thankfully. Well, except when I foolishly decided to rip a few donuts on rough terrain with only 18 psi in the tires and lost bead on one tire. Play stupid games, win stupid prizes!
