Want to switch from TBI to TPI...so I will be getting a new Walbro High-Pressure
255 ltr/hr pump.....however...About a year ago I got a flowmaster exhaust installed at a muffler shop...and they welded everything....I was thinking of taking my car to a shop...and have them do the fuel pump swap....so they can weld the exhaust back together..and i wont have to deal with it...first..it shouldnt be THAT much money in labor should it? Second...will my TBI system beable to handle the new fuel pump....it'll only be temporary (from the shop back to my house)....I am a bit confused because I know TBI uses like 12psi fuel pressure...and TPI around 40 or so...but will the TBI regulator do its job and take it all the way down? Thanks for the info. Also...any recommendations as to where I should take it? Should pretty much any shop beable to do it? Should I be there and watch and make sure they do everything right?

With the cost of the new pump, it was over $500 for the new one to be installed in my car. But then again, I never really found out how much of that was the cost of the pump, or how much of it was the labor, so it could be pretty costly. I think to get to the fuel pump inside the tank, you have to drop the rear end, the tank, take appart the tank and install the new pump, quite a bit of work, so it could be 4 or 5 hours worth ($240 - $300) in labor alone. I do think that the FRP should slow the fuel down enough that you wouldn't be running at an unsafe fuel pressure.

Man....well i guess I'll have to do it my da*n self....oh well...my only problem is having to cut my exhaust....guess theres no way around that....unless I take it to the muffler shop...have them cut it off and store it for me......drive home...do the swap...then drive back and have them put it back on.....hmmmmmm..........i shall see.
