190lph fuel pump good for around 280fwhp?

I hope so I just ordered the fuel pump lol I thought the 255 or whatever it is, was too much overkill... My stock pump is about to die anyway, it's even starving my stock 5.0L LOL

plenty

If you don't plan on running an FMU then it will be fine. Most of the Walbro 190s internally by-pass at around 60 psi (not sure why).

I supported roughly 300 RWHP on an 88 LPH pump with a Boost-a-pump. At 17V it provided around 137 LPH while the 190 provides roughly 176 LPH at 12V. Both flow rates given here are for 40 psi.

Plenty......

cool thanks, do you guys suggest an aftermarket fuel regulator?

Not needed at your level, but for the sake of adjustmentability<~~~ is that even a word? and future mods, if you are replacing it anyway, get the Kirban!

Aftermarket FPR is always a nice addition. Kind of a pain to install but if you are going to get it tuned it's suggested. Look into a Kirban.

I have a Kirban, easy adjustment!

I have a 190lph, it is one of the last things I'm worried about as far as fuel delivery and I have roughly 340-350bhp.

So I wouldn't worry, it's 'plenty'

Another vote for the Kirban. I've had them both on my 5.0L and my 4.6L and it's a good looking, high quality (billet), inexpensive AFR for the money.
