Decided that it's time to be proactive regarding my fuel pumps (among other items) - 30 years old and history prior to last ten years is unknown. Crusader 454, '82 vintage.

I brought them home this winter and noticed screws and a plate on the bottom. Anyone know if these are rebuild-able ? Or do I lump the $200+ each I see online....

I see the water pumps also have a similar backplate with screws so I might as well throw out that stupid question too.... Rebuild-able?

Thx

yes some are repairable, did it once to the fuel pumps on my 454's. The second time I just replaced them. Water pumps which ones block circulation pumps or raw water ?
 
+1 on what alexander said. For the difference in cost and aggravation of rebuilding.....I'd replace.
 
Thx for the inputs!

One more challenge... Tore down the raw water pumps to replace impellers. 1 has a lot of shaft play so I assume that means the bearing also needs replaced. Shaft does not exhibit any wear, but i can see wear marks on the mating plastic Race the shaft assembles to. So same question as the above - can I more economically replace just the bearing or does the entire pump assembly need replaced? I see a clip at the base of the shaft, so I assume remove clip and carefully tap out the shaft.

After some research, there is a major rebuild kit (with bearing) available online for Sherwood RWC pumps for around $130, vs full replacement for >$500 (I think I just answered my own question....
 
If you google the part number, you should be able to find a replacment pump for around $200.
 
I thought I found it for quite a little less, $70 or so, but I sure can't now.
This'll probably never happen again, BUT... I bought a new Sierra brand pump for our 5.7. Similar to the one pictured in Charlie's link. Installed it, started the engine and the pump leaked like crazy. New pump so I was sure it was a connection or the like. No! Turned out the little "dome" casting on the very bottom had a pore in it that I could stick a straight pin through. Vendor was willing to express another pump, but I just used the casting from the old one in place of the one on the new pump. I'd planned to rebuild the old if I could find a kit, but at that point I just pitched it.
 
Yer right JD. I was thinking of the price of a raw water pump. I just purchased new fuel pumps for my big blocks and they were even less than $70 each.
 
My bad. I went and looked at the invoice for the last fuel pump I bought. It was $110. I'm having more and more bald moments as I get older. Maybe I just wanna live in a state of delusion-after all-we have 4 more years to look forwward to.
 
Update
Ordered the rebuild kit only to find the pump was shot. Going to switch to a crank mounted setup on one motor and see if I like it. 1 less belt and I hear you can change the impeller blindfolded in under 5 minutes.

Stripped the engines and acid dipped all metal parts, followed by fresh engine enamel paint. Rebuilt the starters, alternators, carbs, oil cooling hoses, and port RWC pump. Replaced the thermostats, water temp sensors, engine water and fuel pumps. Repainting the blocks and manifolds too. New wire reinforced hoses all around. Should look like new installs by Spring... And my confidence increases since I have no idea when the last time these were paid attention to, on a 30 year old boat...

I'll try to remember to post some photos once all is completed.
