FiTech swap

Hey guys I tried searching the forums but honestly nothing was showing up for my questions.
I am rebuilding my L98 and will be running Fitech EFI. I'm wondering if anyone has any info on what fittings I need to use my existing fuel lines? I'm upgrading the pump, it's a Arizona car with no rust so I don't see the point in replacing lines! Any help is appreciated 👍🏻

Re: FiTech swap

I'm going to be using these for my Holley terminator system -

EAR-AT9894DBJERL on the feed line M16 x 1.5 to -6AN

EAR-9894DBHERL on the return line M14 x 1.5 to -6AN

This gets rid of the factory rubber section and attaches directly to the hard lines. I didn't trust the 35 year old rubber OEM fittings.

That's not a bad idea. Didn't think about the rubber lines. Probably because they look in good shape. But better safe than sorry. Thank you!

Re: FiTech swap

On the same…kinda…subject, do I have to replace stock injectors and fuel pump when installing FiTech? I’m replacing a stock 350sbc with a crate 350 with upgraded cam, heads, etc. I wonder if upgraded pump/injectors are needed. Or a fuel regulator would suffice? Thanks for your feedback.

Are you keeping the tpi-setup (including pump and fuelrails with stock regulator) to bolt on your crate? If so, then you're all good. If you decide to put bigger injectors you just put in the new value in the fitech. Stock tpi 350 injectors are 22 lbs.

Thanks for the response.

That should not be an issue, as long as you know the size of you injectors and run stock fuel pressure. I run Accel super ram, stock injectors and pump.
