Install the pump per the VFAQ for "mustang walbro pump in a DSM" This will save you a lot of headaches about the O-ring leaking and if you use the insulation wrap around the pump it is pretty quiet.

With that big pump you will also likely need an adjustable fuel pressure regulator. Get a good one like Aeromotive or Paxton, don't bother with the B&M.

I don't know about everyone else, buy my Wally 255 fit in just fine. I used the piece of fuel hose and clamps to connect it instead of the little o-ring deal and worked really easy. Now the sending unit itself was a whole other story thanks to rust.

Buy your pump from www.autoperformanceengineering.com . Buy the GVR4 pump, obviously.

And anybody that claims their fuel pump is too loud is a big puss and shouldn't be driving a performance car. Yeah sure, it's okay to have a loud ass turbo and exhaust that drones through everything, but that little fuel pump whine that can easily be covered up by the radio or ignored is just terrible!

I'm curious to know if anyone can debunk this, but I heard it hypothesized that the whining is worse when the pump is not rewired (pump starving for voltage/not up to speed).

Has anyone installed a bigger pump before rewiring and noticed any difference in sound level?

My 255 is not rewired and if I have a full tank of gas I have to pop my trunk lid and really try and hear it running. When tank is empty I can hear it when I am standing at the rear of my car, but I have never yet heard that thing while sitting in my car. I even rode in the back seat for the first time a few weeks ago and no noise.

I can only hear mine standing at the rear of my car or when I pop my trunk. The amount gas or when It wasn't rewired didnt play a factor in the noise level. I have a rewired 3si VR4 pump in mine. That shit ain't loud! Get an external wastegate and start complaining!

that 3si pump is NOT a direct fit. i had to bend the bracket, and use a hose clamp. i have a spare and another stock pump, if anyone wants pics.

Almost every mod requires a little 'custom fitment'. Hehe. I completely forgot that I had to bend the bracket and then some to make it fit, thats how often that stuff happens! [Big Grin]

My Supra fuel pump definitely makes some noise. Its uninsulated and unrewired.

Some noises add to the car. I gotta admit that I kind of like transmission gear whine. My buddy ran his 944T out of oil once and it has this great racecar-ish gear whine now... [Wink]

Maybe I'll have to get those TRE straight cut gears.

I installed a 255 a month or 2 ago and it was cake. Its no big deal to install it. The only things you would have to do are to bend the bracket down so that it is straight and use a hose clamp to secure the pump to the bracket. The 255 is just a bit longer than our stock ones. I dont understand where people are putting this peice of fuel hose as that would only complicate things. It took me all of 30minutes to do it and get it running again.

My 255 is loud as fuck, but I just ignore it. People are always asking me what that noise is and I just act like I dont know what they're talking about. btw, my 255 is not rewired but my friends is and his is almost silent.

Actually, I think it makes it easier with the fuel hose. If you cut off the flare part of the housing that the pump nozzle inserts into with the o-ring you can install the pump without changing or bending any other part of the bracket because this in turn allows you to install a larger (longer) pump. And you also have no chance of a leak at the o-ring since there isn't one. www.autoperformcaneengineering.com actually sells their kit with the correct amount of hose and the clamps along with the new fuel sock and pump foam sleeve. The hose just goes on the pump nozzle and then the other side to the metal tube where the flange part was cut off. *Simple*

I have a 255. It is loud both in and out of the car. I have run with it re-wired and re-un-re-rewired (huh?). It makes no difference in noise level. It was an easy fit. I had to buy a longer screw and bend a bracket a little. Not that this hasn't been covered before

the supra pump does not just drop right in.
it takes about 5 minutes of modification to get it to fit though. it works fine on DSM's but our galant tanks aren't as deep and it hits the bottom unless you mess arround with it. not hard to do though

the fuel hose is a good idea, but it will deteriorate in the fuel. it'll take a while, but it will go. they use viton and neoprene, and it is expensive. bmw had intank prepumps for a long time, and they used this design, where the pump is connected to the feed tube by a neoprene hose. over time, the hose would turn hard and shrink, and split. then, the pump would pump air with the gas. this is still common on those cars.
