Default Changing intank on a 98 what's the difference from other years?

I'm going FI and have to get a better fuel pump. It seems like an inline is the easiest way but I hear it's better just to do an intank. Got a couple q's.
1.What is the difference between 98 and previous years when cutting trap door?
2.Would the vortech inline provide enough fuel?

Thanks for any input and yes i've searched...sick of reading through threads that don't give awnsers.

Do an intank pump over the inline. The inline is basicly a patch and will not pull extra fuel through the stock pump it will help keep pressure up but not any more volume. The intank pump will provide you with all the fuel you need for even some future upgrading.

Other than additional noise, the only drawback to the inline pumps are they are sensitive to inlet restriction. You need to have large pickup lines from the tank to keep from starving the pump. In-tank pumps do not suffer from this problem as they are essentially sitting in the fuel. If you run an inline try to mount it below the tank level to allow it to feed better.

Hope this helps.

Yes it does thanks for replying. Do you know if cutting the trap door method works for the 98 year like the others? The sticky above referenced years 99-02...but not sure about 98?

I also have done the trap door method with no problems. Main difference is there's no bucket on the '98s and the pump sock is different (bigger).

Is there any kind of write up for doing this on the 98's? Can you maybe send me a pic of where to cut?

Thanks,
Curtis

What do you mean by not incased?

The '99 and up have a bucket that the fuel pump sits in. The '98s have baffles in the tank instead. No bucket.
