Is it ok to just go to the local Autozone and get a water pump for my 4.3l or do i have to get a "Marine" water pump @ a premium price?
Also looking to rebuild my Rochester carb, any good links to where to get a rebuild kit?
While I see and understand your thought process of the above as a do it yourselfer! But another thought process should be knowing the pump could internally fail to where the naked eye can not see at any giving time with out total teardown, and as time goes by of not knowing how long the auto pump may actually last, there comes a time where your gambling luck could run out while out on an open body of water with no one around to tow you back into port thus stranding you for a while to either the engine cools down long enough to try and go again or hope someone like tazrig comes by before dark.
I can't speak for all carburetors, but there are some models that require you to use the correct accelerator pump spring sometimes called the delayer spring, duration spring or garter spring and in some cases they can be color coordinated for best tension settings for proper fuel amount, etc. As it seems you found out, It's also important to use the correct length and width accelerator pumps thus the reason for finding the correct carburetor kit for the application is important. Preferably a marine carburetor kit is ideal to help eliminate some of the issues mentioned above.
Hardly worth saving a few dollars and going with a non marine pump. Penny wise pound foolish.there comes a time where your gambling luck could run out while out on an open body of water with no one around to tow you back into port thus stranding you for a while to either the engine cools down long enough to try and go again or hope someone like tazrig comes by before dark.
