One of the Arizona Walbro dealers sold me this onea couple of months ago to put in my Typhoon instead of the 255lr/hr one that I asked for because he said that the #394 is way better and thats what all the mustang guys are using. I took his word for it because he is an authorized Walbro dealer. Well, I have done a lot of other mods to my Ty and I am getting some really bad knock in upper gears if I even try and get on the gas. Arizona gas I have heard is not very good, so I plan on putting some race gas in this weekend and see if that clears things up. My question is that has anybody ever heard of a Walbro fuel pump #394?

Friend of mine got one for me but not sure this is right one for Ty and 255 l/h...

Is this right one?
Here is what he could read on the box

WALBRO
GSS341
05104-1
PAT 4500270 5421303

Thanks midnightbluS10 for your reply, I also did search by google but I was still wondering that it can be direct bolted on for Ty or pump itselves were all same size... and the harneses, I want to make sure before I start this hard work that I can use this harneses or not, because venders are usually selling this pump w/ another P/N's harneses.

No, it won't bolt up directly inside the gas tank, it took some major modifications to get mine to fit inside. The 341 seems to be a little bit longer and therefore won't fit inside the stock mounting. If I didn't already have the truck appart, I probably would have taken it back and gotten the right one. But now that it is in, I haven't had any probablems with it.

AZTY, thanks for your reply, I found this page at Auto Performance Engineering and the P/N GSS341 is comming only pump and the pump is small, offset inlet opposite outlet and is for 240SX, RX-7. So it seems like it won't direct bolt onto my Ty.
