Any particular preferences as regards fuel pump manufacterors/sources for a stock carburated 225 circa 1970? Seems to be a wide range of quality with basic replacement parts(pumps,filters,bulbs,switches ect.) these days.Vehicle isn't in regular use but over full crank-case with too thin oil with strong oder of gasoline indicates failing pump? All input appreciated. Thanks. |

Well, overly-full crankcase with strong smell of fuel does usually indicate a defective fuel pump, but if your '70 is a California model with the carburetor's fuel bowl vented via a hosepipe to a fitting on top of the fuel filter's body, a grossly flooding carb or a badly defective fuel tank vent can cause the same problem. Most all the slant-6 pumps available today are the same (except for the '70 California + '71 all-states/Canada w/that extra fitting); there's just one company making them and all the brands just buy from that company, as it seems. I'm sure there's extra-cheap junk from China coming in, so do try to stick with a reputable brand. Blackstone or Carter or TRW or NAPA... |

Dan and Achille, I have recently been thinking about using an in-tank or electric in-line pump . Reason is I'm gonna have stuff off the block to swap cams and if pump is off, now would be a good time to block the pump hole and change pumps. Now this is a case of fixing what isn't broken if there ever was such a case, but I do that fairly often to see the effect. I haven't found a slant six pump hole plate but could make one easily enough, but wonder if a 318 plate will do as well? And if there is a favored in-line or in-tank pump? thanks rock '64d100 |

Y'ask me, electric pumps are a damnuisance to wire up, mount, and set up correctly and safely on carbureted cars. |

I believe there are 2 or 3 sizes of fuel pump flanges that cover a majority of engines. The one I used was offically labeld for a jeep 4.0 which I think is also same for a SBC - take a gasket with you and go to auto parts store, in same section where they have the flashy chrome doodadds like hose coverings they usually have these as well. Walbro pumps are good - www.apeusa.com |

While other pump parts such as the lever arm were different, the flange design is the same for a small block Mopar, slant six, big block Chevy, or most Fords. I guess they all bought their fuel pumps from the same sources. |
