I bought a fuel sending unit repair kit for my 1999 silverado 1500 z71 and am having trouble installing it. I do not see how to replace the wiring on it without splicing them. Any suggestions?

You have to splice it. It should come with heat shrink butt connectors. IMO throw them away, solder and heat shrink your wires.

Never mind I read that wrong. I thought you were talking about the fuel pump replacement harness.

His kit is different than mine, mine doesn’t have plugs on the pump, so i don’t see a way to connect the wires to the pump

I bought a fuel sending unit repair kit to fix the fuel gauge on my 99 silverado 1500 Z71. The kit looks relatively simple and straightforward until you look at the wires, it looks like there is no way to connect them the to inner piece of the fuel pump without splicing them. Any suggestions?

Whatever you do, make a WATERPROOF connection, especially if you live in the rust belt.

 

I'd use heat shrink crimp butt connectors on that. 

 

Don't have to buy this many if you're not doing this for a living - this is just to give you an idea of what to look for. These here even have solder inside, in addition: https://www.amazon.com/Shrink-Connector-Assortment-Plastic-Organizer/dp/B00B7IIXDA

Not all heat shrink is the same, you want adhesive-lined heat shrink for this application.

I've never seen heat shrink connectors WITHOUT the adhesive.

 

I've bought them here before: https://www.sherco-auto.com/krimaseal-usa-made-heat-shrink-crimp-and-seal-connectors-and-terminals.html

 

Del City, and CableOrganizer are a couple other great places for quality stuff.

You can get them in many configurations...I get a lot of stuff through DelCity.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Z45 · Posted

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
