Default Inline pump, pro and cons

Hey guys!

Additonally with my h/c/i swap i'll be thinking about a fuel pump upgrade, car is '05 CTS-V with saddle tank and i'm hopin on 450rwhp with 42lbs injectors!

For less stress and not heavin the time to drop the tank to build in Walbro or Racetronix, i will try this way maybe...

I will build in bigger feet or return line and a fuel regulator, so i have the same results with a Bosch 044 like i go the in tank way, where is the different or the loss here?

Thanks in advance...

You might give this more time. One disadvantage of inline pumps is noise. Not sure that is an issue with you.

I do alot of ls swaps in the older cars and trucks. 90% of the time i use a inline pump. Makes it way easier when a vehicle originally had a carb on it. On yours if u want to run a inline pump, thin plumb it up and have at it. Works either way.

But if it were me, i would install an intank pump. Easier to just remove the original pump and replace with new one. Alot of headache, money, etc. Saved!

Inline's can make a lot of sense on old, carbed cars as noted above.

Default Dual Fuel Pumps = OEM

Hi Ron, MOST performance cars built by OEM's use Dual Pumps.

The first pump is in/near the tank AND the second pump is "mid" car, an inline pump.

YES, use a return 1/4" line back to the tank from the rail regulator output.

I manufacture Fuel Pumps, inline billet case.
My site is PanteraEFI.com, "see" new products, fuel pumps.

Ok, thanks for positive post going that way, it encourages me doing that...

So i can use the installed oem line in 3/8" with 8mm inner diam to feed the engine and return maybe 4AN with 6mm inner?
