    Pressure rating for inline fuel pump

    I'm trying to replace my fuel pump, and decided I'd try going the inline route to save time and effort. I found a thread here from 2013 that listed the fuel pressure between 38-53 PSI, but the ones I can buy locally are either 3-5 or 5-10 PSI. Is that other number correct, and I need to look for a higher rated pump? I appreciate any assistance, thanks.

    Going by the year you've stated on your user array your truck will have either a 2.4 4G64 or a 3.0 V6. Both of these engines are running fuel injection - you will need a high pressure fuel pump. The pumps you are looking at are suitable for carbs.

    It's the 2.4l. I've been researching all morning, and I think I've found one that should work on Crapazon. It runs up to 300lph/80gph at 43psi. Thanks for the response. I'm ordering it now and I suppose I'll see next week if it works.
