mine has the broken tank baffles too.that sounds like your issue. rock auto has it for relativly cheap but im also having some evap codes and the sender tubes and filler hoses look terrible so replacing those makes it quite a bit and i want to replace it all if i drop the tank. everything is rusty as heck so its not something you want to do

The is a rubber diaphragm inside the FPR that moves up and down based on vacuum to regulate fuel flow. If this diaphragm tears, gas leaks through it and is sucked into the vacuum line and into the intake system. If you smell gas in the vacuum line you should replace the FPR.

Good catch on the vacuum lines. That definitley needed some attention.

I don't know if replacing the FPR and the vacuum lines will solve your issue, or if it is related to broken baffles in the tank like the other guys suspect, but I always start with fixing the obvious stuff and seeing where I end up after that.

Yeah, I'm not going to drop the tank. Are the baffles something easy to replace or does that just require a whole new tank? Because my dad and brother are both mechanics so if THEY want to do it, I'm not going to stop them

Even if not, it probably needs fixed anyway.
Can anyone find one cheaper than $55?

Baffles can't be fixed. If that is the problem you need a new tank. They are not that expensive but changing them can be a PITA.

Dang. Do you think that might also fix my cruise control? Or would that have nothing to do with it? Only reason I'm asking is because I noticed the CC vacuum is tied into the same lines.

Yeah I figured that after looking on google for tank baffles. Advance Auto has a promo for free shipping and 15% off right now. So I can get a new tank for $93.

Do you guys recommend I also get a new sender assembly and pump?

Thanks! You guys are the best

If you can afford it, I would definitely put a new sender and pump on when (if) you change the tank. On a 94 its not a matter of whether or not the pump will fail, it is a matter of when. Most of the hassle in a new pump is dropping the tank.

You might be a computer nerd, but you seem to have a good grasp for this stuff. You ask good questions and focus in on the solutions pretty quickly. Keep hanging around and we will make a backyard mechanic out of you yet.

Thanks I always wanted to be more of a mechanic.
What do you guys think of
this fuel pump this fuel pump
and
this sender assembly this sender assembly
? The pump worries me because its about $70 cheaper than any other pump that works with my car.
Will I need anything else? Fuel tank lock ring, fuel pump socks, etc?

If its not A/C Delco fuel pumps, stay away. I had an Airtex fail on me before 2 years.

It should come with the pre-filter sock.

Yes, get a lock ring before you dig in. Funny thing is, Autozone carries my fuel pump for my Blazer, but does not carry the lock ring(special order)yet more than likely you will need to replace it when you reinstall because it rots out easy.
