I need a new fuel pump but do not want to throw a stock one in because I'm gonna need to upgrade shortly anyway. So what pumps are good with minimal modifications I don't want to reinvent the gas tank or something crazy like that haha. I just want a good 255 to 340 lph pump that will slip right in. I was thnking aeromotive but I'm having a hard time finding one finding one that will work.


Thanks guys and yes I searched!

you cant use aeromotive stealth becuase it is return system, our mustangs are returnless. Im personally going to go with a svt focus one.

Thanks for the response I was thinking about the svt focus pump but I went with a walbro 255/317 LPH pump that I ordered from UPR. I've never dealt with them so hopefully there a good business and hopefully that's a good pump!

Do the walbros drop straight in like a SVT pump does? Seems to me that you might run into a few fitment issues and have to do additional wiring with it.

False! You can use a return style pump on a returnless setup, it wont work as good. But with the Aeromotive 340lph it will work good on our cars.

OP, a Focus pump will slip right in.

Just because you "can" do something doesn't mean its a good idea. the fuel pressure will be all over the place and the pump will probably burn out much sooner because they are not designed to handle varying voltages.

i maybe the exception to the rule...but i've been using a walbro gss 342 for 11 years and 55k miles with my Novi 1000....will agree that Fuel Pressure does bounce all over the place.....and I am setting up for something different to be safe...

The walbro 255 will not drop in. It's taller and you'll need to modify the fuel pump housing to make it fit.
Yes I read that it takes some modifications I just wasn't quite sure on what exactly it required. Ill see how I like this one and at worst ill switch to the svt focus pump. Do you have any tips on how to make the walbro fit in the basket?

Get a supercar pump. It will be alot better for you. You do however have to do a little modifying but it's well worth it. I have one in my car now and am pushing 450 rw without issues. The Focus pump was only good for me right around the 380 mark.

+1, I am pushing 424hp(mustang dyno) and I am at 78% dc. besides a dual pump setup, a supercar/bap set-up is a very good way to go

I had to dissassemble the basket and remove the syphon and add some holes to the basket to keep it filled. Make sure you put them in the front only. Lol.

I also had to cut the ring section around the top that holds the pump in place to make it fit. I deleted the pprv while I was there but you don't have to. Also you'll need to splice on the new connector or make one for the walbro. I used to have pics but I lost them.

Ok cool thank you. The guy at UPR told me to cut a hole on the bottom where the pump would sit and slip the sock under the basket and walla. And then of course I was gonna drill the holes in the basket. And the new connector comes with the kit I ordered. Also how did you do you pprv delete would it be good for lower horsepower mustangs or should I keep it? I heard it can cause shuttering at some rpms. But then again I've heard some bad stories from it being removed.
