hello..i do not know the specifics of your inline 6, but i recently added an electric pump to my 292...WOW what a difference!!!!...seems the last 2 mechanicals i bought just didnt work well...by changing to electric i have quicker ,easier starts and runs great...I also have a fuel regulator...
Carter makes a universal pump-if can be bought at NAPA....I will get part # later....
hope this helps.....
