    Here's a quick pros/cons for each type:
    Inline pros: Easy to get to in case of failure, least cost.
    cons: has to be mounted low because they need to push gas, not pull it
    is noisier, tend to overheat, need a pre-filter
    in tank pros: Cooler, return and vent fittings are integrated,
    cons: more complicated to plumb, have to drop tank unless you've cut an access,
    Probably need a new tank. expensive
    Holley all-in-one pros: Use your current tank, use your current feed line, no return
    cons: connection to current feed line is not optimal for high pressure,
    Have to drop tank unless you've cut access

    I don't understand that one. I used efi rated rubber hose and clamps, made connections just as you would with factory system. No leaks. Was one of the easiest parts of the install.

    I said not "optimal", not impossible. Clamps are more likely to fail thanpush lock, NPT or AN connections.

    This can be remedied. I used pushlock on my car.
    I flared them fore 3/8 brake line fittings, and put on an pushlock adapter from the hydraulic store. Used pushlock hosing and I was done.
    I use the stock steel lines.

    That's better than using a clamp, for sure. It would have been nice of Holley to provide a fitting for that or nearly anything else. Too bad, because it's a really nice piece other than that.

    Cheapest and easiest: get the corvette filter pressure reg assembly and run an inline pump, done.

    I’ve had both setups.external pump is loud...didn’t like it.

    I now have 4th gen fbody bucket installed in tank. No FPR, one line to front,quiet, no baffling.

    Used vetteworks mount-in a custom make recess to clear trunk.

    I installed a 4th gen bucket in mine as well ...solved my issue as my first set-up was pump on a stick....with no baffling or bucket, fuel pick-up was hit and MISS...
    pros..quite like OEM ...worked fine! used stock tank (I had already made new lines)
    con... drop the tank cut a hole.
