Do I have enough fuel pump?

[Stang D]

Id be running a 255lph if I had my druthers, but my old pump died and a 190lph is all the local speed shop had in stock. I NEEDED to race my new combo that night so I did what I had to do. The 190 seems fine, but I haven't sprayed my new combo yet. Other than a quick 50 shot on the top end las time out. Hate to pull a brand new pump and waste money if it isn't necessary. Combo in SIG. I'm just running the standard FTI 300HP AFR165 recipe. I'll likely spray it a dozen times a year.

I'm using a walbro 190 and I had plenty of fuel while tuning. Only way to tell is to datalog your AFR while spraying.

with the spray im gonna say that you will need a 255... n/a you should be fine with the 190... my .02

Its only 130ish for a 255. Be safe.
