    Default Going back to manual fuel pump. best 1???

    Clay smith? or... The only reason I ran an electric for a season is because I didn't want to cut into the front plate of my rail kit. But now I'm ready to cut it,I'll just have the fuel pump hole cut larger with a water jet. Btw do you have to run a regulator with a clay smith pump?. Fwiw I'm feeding a 557 na deal that's 9to1 , 2 tanks that I draw off of 1 at a time, through #10 lines. I've had good sucess with carter street/strip pumps ,and have 1 of those I could use for free(1 yr. old), just curious what everyone else was using that had a rail plate clearance problem was running?

    You cannot go wrong with the Clay Smith 170 GPH mechanical pump. I've run that pump on several different boat (All blown 468" deals with either 850's, 950's or 1050 Dominators) and have never had any volume or pressure issues. BTW, some were dead-headed and some were bypass fuel systems. The key to optimizing this pumps capabilities, meaning use large enough lines and (I prefer) by-passing back to the tank(s). Jocko

    I use the Clay Smith pump with a Product Engineering regulator (dead head) feeding two 1050's, no problem.

    Thanks for the input, size wise the clay smith deal looks to be about the same size as my carter, I guess I'm chopping either way.

    Ditto here. 170 Carter on my motor. I did have to clock it to have the fittings clear my plate but that's only a 5 minute job.

    I sell those Clay Smith pumps so if you need one shoot me a PM. Also there is a bottom plate that edelbrock that puts the ports on the bottom.

    I am running the CV billet deal. I love it. All of my mechanical pumps on boats will be CV's from here on.

    But no reason the carter should not work, and the Clay pumps are good too.

    Although I have not yet used it....I have one of those too. Ebay special.

    Bought a new Carter pump and just transferred the good parts to the new pump.

    Thanks all. I'll start with the carter, I was just wishing there was a pump that I didn't have to cut into my rail kit to make fit. I have no return lines and I'm trying to avoid the whole regulator deal. My motor/set up isn't that serious, just lookin to keep it simple, cause I'm stupid. Besides that my electric won't prime when the tank is empty, that's real handy when you're in the center of a lake.

    you should run a regulator always. You shouldnt need a bypass though. I hope thats what you meant.

    Check out racepumps .com, I run one of them and they work great, no return lines and yes they need a regulator. They are small enough that no mods are needed to the engine plate. They will pump 450gph and 50psi, enough to feed 2500hp on gas.
