1984 Chevy 454 smokes when warm

Thanks, I ordered up that little spring compressor. : D   I have all the rest of the tools (I can hold the valves with my air compressor and compression tester (just need to pop out the schrader valve)

Here's the filter / pump I found on the passenger side.   I'm guessing I should change them both, it has died going up hills a couple times, seemed to be starved for fuel.  I assume my local auto store should have these?

I would just change the filter first, try blowing through the one you take off in the direction of fuel flow. It should be only a little bit harder than blowing through the new one. think blowing through wet paper as opposed to dry paper filter, that is the difference. If it is hard to blow through then that was your problem. That pump is going to be pricey, it is not one of those cheapies from the big box auto store. It should be mounted back close to the tank though, they are designed to push fuel and not pull it so that could also be an issue. That fuel line looks like 3/8". 1/2 is almost the size of garden hose.

You're right, that filter in the video is 3/8.    I found another filter closer to the front of the motorhome on the passenger side, this one is a larger one that says GF-157 on it and it's definitely 1/2 inch.       

The problem of stalling has gotten worse, I took it for a drive tonight to test some things out and it really doesn't want to make it more than 40 yards or so before dying.  It usually dies just getting it in gear now.   Here's a video of the problem:

It's like this thing knows I'm doing maintenence on it and is screaming for attention now  :)rotflmao   I'm going to change both those filters and the fuel pump tomorrow and see if it fixes it!

You should spend $5 and become a member here. Access to the manual section is worth the meager investment.


And different problem should be started as a new topic.
