Walbro 255 fp for the XB
SimplyScion (Vito) would proably be the best one to talk to Rollhard. He was one of the pioneers when it came to boosting our engines and I beleive he changed out his fuel pump, but I will search and see if I can help find it for you.

Well, since you have done all this before. There is a site that sells new injectors for the 2003 Celica GTS. I was wondering if these were a direct bolt on?

See how its plugged up at the other end? Looks just like a cap/screw. You can run a return line from there.

for those that are n/a you can use the rail as well and use that other port to spray some juice into the rail. As far as raising fuel pressure...the in tank regulator will only let you hit about 55 psi without modding it. Without that regulator in place, the fuel pump will not turn on and you will get no fuel. If you can make something to fit in the spot of the regulator with a larger diameter hole than the stock fpr then you can just use the adjustable one to max out your fuel pressure. Also just to give you the heads up, you will hafta modify your sending unit to fit the 255 lph pump in. If you have a dremel you will see where you hafta cut on the bottom. Dont worry about the fuel pump falling out of its spot either because when you put the sending unit back in the bottom of the pump comes close enough to the tank bottom to help hold it in place
It was the juice that I had read went there before, thanks for jogging my memeory.
Rollhard I beleive I rember people having problems with starting(not enough fuel), when they used a return line(not sure if Vito did). Have you read that before and are you concerened about that possibly being an issue?
