    Default The right electric fuel pump?

    I need an electric fuel pump for my 502 with a Holly 850 4011 vacuum secondary Carb. Nothing too exotic. I know I could probebly use the Holly red marine pump but I don't like vane type pumps! (the motors run hot)
    I am considering a Walbro FRB-13 pump rated @ 43 GPH-6 to 8 lbs. pressure, with 1/4 in. ports. It is a flow thru design with an internal replaceable strainer. The people at Walbro said there are too many variables to
    know for sure if the pump can handle my application. Any suggestions?

    Thanks for the help.

    That's a good point. I do not have a CG approved fuel system; so I couldn't comment on that.

    43 gph sounds questionable to me...

    If you got a fuel pump boss, wouldn't even consider an electric for your app. If you have to run electric, I like the Holley Billet base modles.

    do you have a closed engine compartment ?

    I've been running the new Holley 150 hp's like the above 125's for the past 5 years. They are nice pumps.

    Yeah, I'm not sure the Walbro pump would cut it for my GM thumper. The mallory 110 does sound more like what I should use.
    I read an article about fuel pumps that run the fuel around the motor as opposed to rotary vane pumps, that they have a longer service life. It just had me thinking about it!

    I would think that if one had a fire in the engine compartment (mine is closed) that the insurance people would ask a lot of questions.
    Especially if there was an injury or death involved!

    Be prepared to rebuild that Mallory pump once a year. I just ditched mine and went aeromotive.

    I would expect more service life than that for my hard earned money. They just don't make things like they used to!

    Default Elect Pump

    Best bet is a HD Holley Mech - I didn't have room so after many Holley elect pumps went with aeromotive
    Make sure you have the same ID with all your fuel lines from the tank through the filter to the pressure regulator and then the carbs
    The areomotive is a Marine at a decent price - look at Jegs or Summit

    A mechanical would be my first choice. Unfortunatly GM did away with the pump boss on my Gen Vl 502 and made the cavity a coolant passage, so I have no choice!

    You could probably get a few seasons out of it if you kept the pump in a nice location away from ANY water. My pump was the marine pump (first one i had was the non marine version) and it still needed to be rebuilt constantly. This is the first season I've run this aeromotive pump, many guys here on these forums recommended them so I gave it a shot. So far so good, only time will tell though.

    (GN7)Just a simple waste of perfectly good sour mash. If you need a fuel, use something that will poison you, not something that makes you buzzed.
