    98 XPL fuel pump upgrade help!

    Hi all.

    I have a 98 XPL and have purchased the Mikuni high volume fuel pump. The thing is on the main throttle body that has the old pump attached to it.. it doesnt have a return line (its built into the old feul pump).

    Whats the procedure with this? Do i need to drill out the return like the other throttle body?

    any help is appreciated.

    Why would you want this pump when the stock does fine?

    Hmm...sounds like you missed a bit of pertenant info there on your first post...

    Don't mount it on the engine.

    Stock carbs still flow enough fuel to handle your mods. Look at the RXX with Twins...for example.

    Hi

    I made a stainless bracket to hold the fuel pump and the solinoids for water injection... so should be ok there..

    SO im still lost as to where i will return the fuel from the main throttle body (the one that HAD the original fuel pump) as now the fuel pump is gone the return outlet has gone with it..

    I'd call Tim @ Novi, I bet he has a block-off plate with the return line barb installed...if that's what you need.
