Hello,

 

Can anyone tell me how labor intensive changing a electric fuel pump on my 92

S-10 Blazer? It has the 4.3L engine with the electric fuel pump that is mounted inside the fuel tank. Thanks.

TROYROBO,

 

Thanks for the reply. I'm 99.9% sure mine is the fuel pump because when it occasionally doesn't start(cranks over but doesn't fire), I hit the gas tank with a hammer and then it starts up immediately. Question, did you have to replace the sending unit also along with the fuel pump? Thanks.

The SU and pump were seperate on my 94 Jimmy. The SU on that truck was replaced when the tank was, pump died just over 2 years later, with a full tank, shop LOVED me for that one.

There was a "secret service bulletin" on the spyder injectors. Mine went

90,000 mi. with the originals but lots of folks had trouble much earlier.

 

This should have been a recall since there were fuel leaks around

the intake. "Fire hazard"! :lol:

TROYROBO,

 

I know the sending unit doesn't come with the pump, but someone told me that you will more than likely wreck the sending unit while replacing the fuel pump. That would be great if you could find out if it had to be replaced on yours while installing the new fuel pump.... Thanks.

If money isn't an issue, do both while the tank is out. Of course, the SU in my old truck was replaced with the tank because the shop couldn't break the fuel lines loose without cutting them on the SU side, they were rusted pretty bad. Yours may be the same, this was a few years ago, on a 94.

      Oil Consumption

      By KARNUT · Posted

      No I didn’t watch a video of a person who analyzes oil for a living explain general oil usage. For clarity I did ask my brothers one who runs our equipment business. The other who runs our old ROW business about oil usage. Nothing has changed since I retired. Their personal vehicles or work vehicles use no oil. Not enough to see on the oil checking device. Then I pondered. I like to ponder. In this extended oil changing world with oil change countdowns or lights. If engines used say a qt every 2500 miles or up to even 4000 miles. With oil changes reaching as high as 15000 miles. Normal for most people is eight to ten. Vehicles should potentially be seizing up all over the place. Especially in hilly terrain. Just how many people actually check their oil? Maybe 10 percent. Those are the people that probably change their oil early. I like to research used car listings. I have five favorite dealers I check. They all list carfax with their listing. It’s rare to see vehicles with anything but extended oil changes. Transmission service, forget about it. I’ve seen Honda and Toyota certified vehicles up to 100K miles and ten years old. With nothing but normal maintenance. Isn’t nice we all have different experiences and believe our way is the best. You certainly get backup for whatever you believe. Life would be boring otherwise.

      RUMOR / INSIDER: 2027 Silverado Dealer Reveal NEXT WEEK

      By RobbertClaus · Posted

      Interesting rumor. Dealers near me have been tight-lipped so far, but if this reveal actually happens next week, I'm really hoping they finally give the HD a proper interior overhaul. The competition has been eating their lunch in the cabin department for a while now.

      Oil Consumption

      By Chuck FB · Posted

      There are a few good takeaways in that video that pertain to this thread, certainly the possibility of the oil control rings having buildup, the fuel injectors and how clean or not that they are ending up affecting the pistons rings carbon buildup, and the fact that its normal up to a point for a given engine to use some oil, and that the oil quality that is being utilized is part of that ring clogging up issue as well.   I was talking with a neighbor yesterday who has a baby LZ0 duramax and he had bought it slightly used but it does consume some oil and he has switched over to 5W-30 Euro spec oil and in this case that never made a difference in consumption over the factory 0W-20 recommendation. He finds it uses a quart in about 3500 miles and as he goes a ways over that distance he adds oil to full and goes another 1000 miles or so and then changes oil and is typically at 40% or so left on the oil monitor at that point with his use case of quite a lot of highway miles and more limited in short run use. I don't know what other LZ0 engines are doing for oil consumption but that is what his is doing.

      Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption.   Shut up and watch:
