'88 Shelby Z- How to install an external Fuel Pump ?

[ShelbyZNut]

Hi..I have a stock '88 Daytona Shelby Z with a Turbo II engine (174 HP with the turbo intercooler...). I want to remove or bypass the original fuel pump, and install an external to the tank electric fuel pump. Any suggestions as to what size (cfm flow?) or particular fuel pump to use, and suggestions as to how to mount this and where, and how to route the new fuel lines and what size fuel line...

Thanks.

Why not install a walbro 255 intank? That's what most people go with and it's good to a few 100 HP. If you really want the inline you can get that in a walbro also. FWDPerformance.com

Hey, thanks a lot for the info..I think I'll go with the inline extrernal fuel pump...want to work around that in-tank pump configuration. While it's not a frequent replacement - I always like to have easy access to the pump when trouble shooting problems that do arise. Thanks again for the advice and link to FWD.

I'd also say in-tank... less chance of the pump being hit by normal driving on roads... but from the sounds of it you already had your mind made up before the thread:)

the advantage of a internal pump is it is easier on the pump to push fuel than draw fuel.if you want an external pump i would leave the stock pump in and run the 255 in walbro as a booster in the cowl. i ran my shadow that way for 2 years of spring summer and fall. never had a problem. i wired it to a seperated switch so i only ran it when i know iwas going to run 20 psi.
