4.3 vortec fuel pump

[mesha]

I need to replace the pump in the buggy. The wiring inside the pump fried and so I can just replace the pump. I have to replace the whole unit. I am looking to maybe do an inline pump instead. Most I am seeing are around 90 psi. I am wondering I the regulator on the engine will cut it back to the 50-60 recommended or if I need one that is that pressure?

Any other ideas or suggestions are welcome.

The regulator will bring it down to where it needs to be. In line pumps are easier, but also much louder and tend to fail sooner. Go in tank if you can. If you mount it to the frame, insulate the pump as much as you can so the vibration wont make it to the frame. That will quiet it down a lot. I like Walbro pumps.

yes it will I ran the summit brand inline electric one on my YJ and I have the same pump for my 4.3 in my buggy... I bought mine at parts plus in Tooele

cool. I would do the replacement inline pump, but it is 350 bucks with the whole unit. If the wiring wasn't wrecked it would only be 100 and I would just go that way.

We used a e2000 inline from autozone. $90-100. I am pretty sure that's the number. It's been a few years.

Worked great, we ran a 4.3 CPI out of a '98 s10

I thought they did away with the CPI in 96, My 1998 is not the CPI motor

I was wondering if the e2000 would work.

It's been a while, but I want to say the MPI was 94-95 and looked like I little lt1 and '96 and newer (thru 2002ish) was the CPI with the spyder that went to each cylinder.

I could easy easy be wrong though. It seems like B2 bomber is pretty versed on chevy engines maybe he can help get me straight.

Super easy to hooked up.

Pos, neg, and key switch

just make sure it's mounted lower than the tank so it doesn't lose prime.

awesome! Those can be had for pretty cheap on eBay

And just because no one has mentioned it yet.

Put a good fuel filter inline too. It seems like I found one from a ford tarus that was designed to handle the volume and pressure.

Buy two and put the second one in your tool bag.

As long as it holds atleast 65 psi you will be good

 

[mesha]

minimum pressure is rated at 70 psi, max is 95.

filter on each side of the inline pump and mount it somewhere it will get some air. Heat is what kills pumps.
I used a marine pump from napa that was spec'd for a 454. I was told they are designed to dissipate heat better because the application has them mounted inside a hull with no airflow.

The pump and filter are installed. Runs great and there is no noticeable noise.
I think I will buy a spare for the tool box.
