Power goes away going up hills. We replaced Heui (SP?) pump and fuel filter, cleaned out fuel tank, replaced all of the injectors with brand new ones. Is there another fuel pump?

What about fuel lines? Have they been replaced?

3126? There should be a low pressure pump feeding the HEUI pump. @Snowman_w900 @Wore Out

A 3126 is why the power goes away up hill.

The 3126 and 3116 both use a lift pump. Depending on truck it can be in the tank or inline.

Everyone I have ever seen has a water separator hid out down around the tank or frame rail that never gets changed

That’s funny you say that, we found one on our boom truck that we didn’t know it had after 15 years

I got one in a top kick. I’m gonna go look tomorrow. It’s a gutless wonder.
