Had to replace the CARTER M3672 which I got new from NAPA 5 yrs ago, installed and ran until yestermorn, when I saw a NASTY drizzle of gasoline running off the pump onto my newly acquired driveway shag carpet! This came as little surprise, having at times early in the morning smelled the evil stink of gasoline after shutting the engine off, and once, having seen a residue of liquid on pump and 5 yr old hose, I replaced the input hose after noting how soft it had become.
I installed a wonderful OLD reman Carter, done by KEM many decades ago, which for the moment has restored the punch to this engine which had steadily degraded as the pump diaphragm did after our Phoenix Veterans Day/Babushka Birthday expedition. I'll check the crankcase oil with great scrutiny in a little while, to determine if it has been diluted or not. I haven't smelled any OBVIOUS gasoline admixture to the oil, but I think I'll test what clings to my dipstick. If readily inflammable, it will have to go, despite having just changed it post Phoenix....
Aaaaaaanywaaaaay, the Question here comes to the Thread Title: Which B/RB Fuel Pump is the Most Easily Rebuildable?
I ask because I LOATHE "throw-away" technology, even when superficially cost effective. I've already purchased a replacement NEW M3672 to have on hand for when the moonshine destroys the diaphragm in this NOS treasure I bolted on to keep Gertrude running through the Yuletide. I saw that this older ancestor pump has some little notches which appear to make it serviceable, with some Shop Technique and tools, so I might see to purchasing some modern diaphragm material or even a pre-fab replacement for the right price. I strongly prefer to work over a pump which can be readily opened by unscrewing, as I see on the better class which go for over $100 usually. To wit, I wonder about what pump is DESIGNED TO BE REBUILT.
You Wiser Elder Moparians will be much thanked for some data in this regard.
