Electonic Fuel Pump vs. Original?

My BJ7 origianl fuel pump finally starting acting
up (constantly ticking but no fuel flowing- and
I tried tapping on the thing first!) Now, I've
got the new Moss Motors electonic thing and I'm wondering if I did the right thing. Should I
send it back and get the fancy solid state unit or order an original one or go modern? It's not a show car but pretty darn close. Thanks for the help!
 
You can easily rebuild the original one. If it took that long to go bad you will have many years and miles before it goes bad again. Check the manuels on "how to". Keep it original if you can. If not, keep the stored for the next owner.
There's my $0.02.
 
That's worth more than 0.02$. I've got the "Glenn's" repair and tuneup guide but the process sounded like open heart surgery! Is there a better guide for rebuilding? Or does the
rebuild kit come with instructions?

Thanks for the quick reply. Bet it's a great day
in Tahoe, we've had alot of great days this winter!
 
I agree with Tahoe, keep it original. I would suggest buying a new one if for nothing else, confidence that you will not get stuck on that long summer drive. When I purchased my BJ7 a couple years ago, the PO had put one of those little electronic pumps on it and it just looked goofey. I quickley replaced it with an SU from moss, bolted right in. fuel lines matched up and worked perfectly. mac
 
It's on the car, it works. There's something to be said about "If it works, don't fool with it".

I would bag the old pump, purchase a kit to rebuild it and when I had the spare time, I work at rebuilding it. In the mean time, drive the car and enjoy it. Take it to some shows, ralleys and local cruises. Unless they crawl under the car or you take the tyre off, no one is going to know that you have a non standard pump. Heck, it might even make good conversation if you should happen to meet another Healey person!

I wouldn't expect great instructions with the rebuild kit, however the "official" shop manual is pretty detailed and if you take it a secion at a time, not too difficult.

You say it is ticking. I suspect the filter in the pump is clogged or one of the valves is not sealing. Usually, the contact points fail and the pump quits ticking. A bang then may get the points to work for a while.
 
Keep the original the fuel pressure is correct for the SU carbs. As a side note I found a revision in the MG web site some time ago that detailed putting a transistor into the circuit to handle the current load and utilize the existing points to trigger the transistor. I modified the pump on my MGB and its spare, my Healey and its spare, three other local MGB's, a Mini, a MG TC & spare. All about three years ago, no failures to date in fact I'm think of taking a big risk and start leaving my spare pump at home in the interest of increased trunk space.

I have the same problem with my BT7. It started ticking but no fuel. I tried everything to get it to work, including banging an kicking it. I finally put on one of the little electronic ones from Advance Auto and it works just fine. I took the original into my mechanic to be bench tested. He said it worked just fine and could not find a thing wrong with it ....so I had him take the electronic off and replace original. It ran just fine until I tried to start it a week later. Guess what.........same thing. It keeps on ticking, but will not draw fuel. Any suggestions. <blockquote><font size="1" face="Verdana, Arial">quote:</font><hr>Originally posted by ThomP:

Rick,

What Thom just said.

"You say it is ticking. I suspect the filter in the pump is clogged or one of the valves is not sealing."

You may have loose dirt/rust in the tank that will keep plugging the pump. Some folks put a big filter between the tank & the pump. Others clean the tank & lines.
