    Default Mechanical fuel pump question

    I'm switching from electric to mechanical, my question is ....should i take out the fuel regulator completely, or keep it and still plumb to it?? I'm hearing two different answers (not here on the forum), can someone give me some better insight please. This is not my first boat, but the first one i've gotten into with the mechanics and repairing. Thx.

    Depends on the output of the new pump, they normally advise you, however again not. Anyway anthing over 6-7 lbs needs a regulator.

    I wouldn't install anything that I don't know about. Unless your running some high performance motor, I would get a standard mechanical fuel pump. We need more information on carb and motor.

    I beleive the manufacturers of that pump recommend using their regulator. They use the same pump for Carb and EFI so I would guess that that pump can put out a lot more pressure than you need.

    What combo are you running ? Dual carbs ?

    If your running a lake/ ski - I would stick to a typical pump with 6-8 psi and 130-150 gph rating - will be plenty for that combo -- Those pumps you pictured are capable of supporting over 1000 hp and if you are just starting to mess with mechanics , it is always wise to match parts to the preformance application .

    I think Hass likes his race pump....I have heard of people who don't....mostly priming issues from memory. Unless you have mega hp that pump is overkill IMO. I ended up with a clay smith unit for like 125.00 and that was polished. I would think even that is overkill....unless you are 800 hp plus.

    Thats right

    The standard pump puts out 50psi and the efi version puts out 150psi(they can be converted back & forth either way with a $10 spring change) so yes you certainly need a regulator and you need to know which spring is in the pump. With the 50psi pump you can use the regulator from Racepumps .com or a magnafuel regulator will also work. If its the 150psi pump you will need the reg from racepumps.
    Here, check out their site http://www.racepumps.com/

    I have one of those on a 900 horse drag car. There is no way you can run it without a Regulator. Get a Edelbrock Streeet fuel pump,Part#350-1722 from JEGS. Supports 600 Hp and holds 6 PSI and does NOT require a regulator. And its 99.00 instead of 310.00 like the one you showed. Or a HOLLEY Billet Aluminum, Holds 7.5 PSI without a regulator.
    Part # 510-12-454-25 but its 273.00.

    1 carb, It's a Holley 4 barrel. I bought the boat back on memorial weekend, don't know really what work has been done other than a cam.

    Why did you choose that pump, it will put out 4 times the amount of fuel you'll need. Or do you plan on making it a 1,200+ engine at some time?

    LOL, not anytime soon. Just trying to replace things i know could strand me out in the middle of the lake. Just figured that mech. pump would be best, I have a electric Blue Holley pump now but looks pretty old. From what i gathered from this thread i just need to go with a mech. Holley or similar and not try to go so over the top with the one i was looking to get. Sorry everybody, i'm still getting familiar with the boat.
