fuel pump/turn signal

[jim97gst]

So I just rewired my fuel pump using the FP kit. Half the reason I did this is because of my whinebro changing pitch with the turn signal. From the research I'd done, this was supposed to resolve this annoyance, but it didn't make a bit of difference. I thought it might be because the FP kit has you get the power from the fuse box. I know most people hook up directly to the battery. However, I checked the voltage at both the fuse box and directly at the battery, and they both fluctuate by about 0.1/0.2 volts with the turn signals on, so I don't see any benefit to attaching directly to the battery. Anybody have any ideas? Run SMALLER wires to the turn signals ?

I've seen some sites that sell the Walbro include a "beer cozie" type thing to quiet it down, but only for other cars. Is it just a piece of rubber? Can I just find a piece of radiator hose that will fit it?

I think I'll go with something else if I can't quiet this thing down. Will an Evo VIII pump drop into a 2G FWD? Should it flow enough if I max out my 16G? Any other reasonably priced quieter options?

I don't want to hear anything about how I'm whiney about my whiney fuel pump. I can deal with a loud exhaust and motor mounts that vibrate the car, but I'm kinda tired of this. It's just louder all the time now with the rewire.

haha, let me know if you fix it! I have the same problem

I have the same problem you do, although mine isn't as loud. From what I've seen, the Evo pump is a direct drop in and flows right around what the Walbro 190 does. It should provide enough fuel for your 16g, no problem. A buddy of mine used the beer cozie thing on his pump and didn't make a bit of difference.

Mine does that too. It only "annoys" me when I forget to turn my radio on. Or when I have the radio off to listen for funny DSM sounds after the car has been sitting for a while.

However, the more I think about it the more amusing I think it is. Maybe a bigger ground on the battery to firewall will fix it? I don't know.

NEVER go smaller on the wires. Smaller wires lead to higher impedance (resistance). Higher impedance means lower electron flow. Lower electron flow leads to noisier systems. Anger leads to suffering. That is the path of the Dark Side.

You have to understand that our fuel pumps are voltage regulated. You probably found that the stock system ran about 13.8v, with the engine running, prior to installing the larger wire. You should find that the voltage now reads closer to 14.4v. Larger wires lead to higher voltage. Higher voltage leads to more fuel flow. More fuel flow... I'll leave it at that. You might also try to make the ground wire of the FP larger as well. We all know that electrons flow from negative to positive, right? So, your size and quality of the ground is just as important as the power lead.

I hate to say it, but it sounds like you need to suck it up and drive on.

I'm assuming the smiley face with it's tongue sticking out meant that he wasn't serious. But it's good to see that I'm not completely crazy by suggesting a bigger grounding wire. I plan on adding one or two 4-gauge grounds to my battery for my stereo system.... some day....
