    Default Primer fuel pump

    OK, let's start another thread to argue over.
    I am looking for a fuel pump to be my primer pump. I have been using the auto zone flo through universal deals. I forgot the brand. Problem is the alcohol eats them up from the inside after a couple years and black goo comes dripping out. ALSO I need something with more pressure... 10 pis ish. I have a nitrous fuel solenoid to act like a check valve. It seems pretty bullet proof. I was considering switching to the one way check valve deal. Little -4 with a spring check valve.
    Any suggestions? My mount is made for a round pump with a 1.750" body.
    Who is the big fuel pump folks... weldon, or walboro or???

    Not sure if its will make enough pressure for you, but depending on how tuff you are, it might. The GN 305 ran a big and ugly for 2 or 3 seasons in the GN class. As you know we start the race from a dead engine start from the beach. You get off the beach quick, you you're toast.
    They used a squeeze bulb primer from a outboard. They got it down to a science. Like three sqeezes just before the starter or what ever. It was a pretty consisdent starter while it had that big ass hat.
    With the electric, how did you know how much fuel you were squirting. Did you hold the bottun for X seconds and then light it?
    Why do you need the primer. Can't you just turn around and hit it with a squeeze bottle?

    Now you can tell me to FO here, but, why do you need a primer pump ?

    ( me the smartass ) if you plumb the system correctly, you don't need it !

    Think about how the fuel system is plumbed, I'm guessing it is just like Endrle told you to do ?

    Think about how the hat nozzles are plumbed, think about how the fuel runs out of the lines when you shut the engine down ?

    Think about having fuel behind the nozzles at all times ?


    Mount the fuel dist block lower than the nozzles, the fuel will stay there in the lines for your next start up !

    There is a guy in the Nashville area at alkydigger.com who has a ready to plumb in primer for $145. He deals all enderle and hilborn new and used. I think it plumbs right into the distribution block and has all the fittings etc. ready to go. Must be enough of a market for it to put together the kit. Just saying...

    Theres a market for these too. But I just use my finger. Just because somebody sells something, and people will buy it, doesn't mean there is a need for it. It means there is a dumbshit born every minute of every day.

    I've found that if your pumping fuel into the dist. block with a nitrous solenoid to check it,the solenoid will bleed off fuel when the line pressure comes up, call it a bypass of sorts, it is not a check valve. The #4 spring check valve does work.
    Another way i have done it was to run a big check valve just past the injection pump, which holds fuel in all the lines above the pump.
    And yet another setup i like is what we call the stupid bottle, it's just a 6 to 8oz bottle mounted behind the hat, with a solenoid mounted on it with a #4 line going into a nozzle in the hat, using a momentary switch when you crank the engine over the blower vacume pulls the fuel in and when it starts to blubber you let off the switch, and it's up and running, and it's hard to flood it like this.

    Coolest set up I've seen is to use a small, air tight aluminum/fiber bottle (CO2 bottle from a paint ball gun works) or better yet, the ice tube in their fuel tank. Put a schrader valve in it so you can pressurize it. Put the fuel solonoid on the near a dedicated nozzle in the hat, fill it half full of fuel and the other half with about 30 lbs of compressed air. Get you several starts and more consistant than flipping a pump on and off.....

    I didnt mean to piss in anybody's Wheaties, but the OP asked a question and a fellow boater answered the question. Some like to wiggle a couple switches and have the beast start but I guess the squirt bottle adds to all the mystique and mystery of getting things rollin'

    You can skin a cat as many ways as there are knives to do it. Seen more than few K boats and MFI injected street cars that never needed a pump to get started. I guess some need it, some don't.
    I see alot of things for sale that have never been able to figure out why someone needs it, but they sell the hell out them. Maybe that explains why I am not a zillionaire. Underestimate the need for some products.

    Whew... I started this and went to bed.
    1) Nitrous solenoid will bleed off pressure... I have wondered about this. I had no way to verify it, though. I only have about 100# fuel pressure at max rpm. This is also the reason I bought the #4 check valve from goodvibrations.
    2) My little airtex pump barely had enough pressure to open the check valve. (#4 that opens at about 4 psi)
    3) Is my system plumbed properly and do I need one: Yes, no, and it is convenient. I push the button for 2 seconds, crank, fire, another little burst, run. It is faster than crank, crank, crank.
    4) Speed Sports uses the pressureized container with gas/ air pressure/ solenoid to start. I don't carry any way to pressurize it... not even a bicycle tire pump. I carry to much crap already. HA

    I shut off the engine with the fuel shutoff. I usually let it run a few seconds after hitting the shut off so fuel somewhat gets sucked out of the lines. In the couple times I had a pump failure I just hit the fuel shutoff, then ignition which left plenty of fuel in the lines.

    So, to sum it up... I could change my shutoff procedure to eliminate the whole deal... a few times, however, when starting is a problem, the primer allows me to shut off igntion, shut off fuel, crank with butterflies wide open (if flooded) and restart procedure. It is convenient.

    So.... any pump ideas?
    I like some ideas that have been posted, but I am lazy and don't want to have to make a bunch of shit. I have nitrous solenoid, and check valve, and plumbing.

    Thanks

    More info...
    My hat block is above nozzle level... as are 99.9% of em.... just from enderle.
    My port dist block is below nozzle level, but that doesn't open until 15 psi ish.
    I prime into the PORT distribution block, so all cyls get fuel. (and it is convenient... lower, less plumbing flopping around, etc)

    My fuel system is just like 80% of the others. Nothing tricky here.

    Lets try this again. I read the part about wanting a PUMP setup and (dislaimer here) I'm not getting a commission check for this: the setup from alkydigger is pretty straight forward. self contained, fairly neat and tidy, has an intermittent switch and AN fittings, pump, lines, and a nozzle. It looked to me like UPS shows up with what is needed and you dont have to drive all over hunting junk to do the job.
