My BJ7 fuel pump "bit the dust" over the weekend. It just quit ticking. I'm a novice mechanic but it looks like a fairly simple job to replace it. Any "cautions" I should be aware of? Also, has anyone used a solid state pump and with what success? Would I need to alter the grounding?
Thanks

Just searched some older posts on fuel pumps. Apprears many of you like the solid state Facet pump. How difficult are these to install? Would prefer to leave the old pump in place.
Thanks

Charlie
 
Hello Carpenter, Why not just replace the old SU Pump with a new Solid State one? I have been running them in my BJ8's for about 15 years with no problems. If economics is an issue E-Mail me off list.---Keoke
 
That is what I was asking about. I'd be interested in knowing which solid state one is considered the best to get and installation tips and instructions.
 
Charlie , I am refering to a Solid State SU Fuel Pump . It looks just like the one installed in the car now and can be obtained to be compatible with either the NEG or POS ground system. Just be sure you know what ground system is used in your car. All original cars were Positive Ground,but PO's may have switched it around.-FWIW---Keoke
 
Charlie,

I still have the original SU pump in my BJ7.
If hitting it lightly with a hammer doesn't work, try cleaning the points with emery cloth. Just go easy so as not to bend anything. Of coarse if the unit is leaking then buy a new one. It seems to me that replacing an SU pump that has worked for 20 or 30 years with a new fangled electronic, solid state unit doesn't make much sense. Unless its cheaper!

I have weighed in on this one before, so here's my two cents as well. My BJ7 came with an electronic pump which the previous owner installed. It seemed to work just fine other than it clicked all the time, unlike the SU that shuts off once pressure is built up. He had cut short pieces of flexible hose with wire clamps to adapt the pump to the original fuel pipes. Quite frankly I thought it looked just "mickey mouse". Of course I like to keep everything stock, even those things you can't see. So I purchased a new SU from Moss, got rid of those wire clamps, rubber hoses, etc., and it bolted right in and worked beautifully. The new stock pump should give you many years of service. mac
 
Thanks Mac:
I think that is the route I will take too. If this one lasted 41 years maybe the new one will too. BTW what was the easiest way to get at it to remove and replace? Rear seat removal or jack it up and remove wheel, or both?? Any special hints? I'll shut off battery switch and ?????

Thanks

Charlie

If you would consider a "slight upgrade" from original, the late BJ8 pump is cheaper & has more pumping capacity. Since it has more capacity it doesn't work as hard & should last even longer. The extra capacity is a good thing to have, since the original could barely supply the engine at full go. You may need a different mounting bracket.

Charlie, I just jacked up and removed the rear wheel & tire when I changed mine out. It's pretty easy to get at. And you're right, disconnecting the battery is "always" a good thing to do. If your last one lasted 41 years, and probably through many years of daily driving, you can expect that with the miles most of us put on our classic cars, you'll most likely be long gone by the time this new one breaks down. Good luck. jim
 
Charlie,

Did you find the solid state pump you were looking for? I use:

NAPA 610-1051.
12 Volts
2.5-4.5 PSI
Gal./hr=30

Cheers
