TR4/4A TR4A Fuel Pump Removal

Hey there,

Hoping to quickly replace the fuel pump gasket. I can access the first 1/2" bolt no prob with a standard socket. However, the rear one doesn't have enough clearance for the socket. Standard box-end wrench too long for the tight space. Any suggestions? Offset box wrench? Crows foot?

Once I get that out, I am hopeful this is not more than a 15 minute job. Ideally, I won't have to disconnect the fuel lines. Simply pull the pump out far enough to clear the actuating lever, scrap/remove old gasket, slip over new gasket (with a bit of Permatex) and bolt 'er up.

Am I off base?

Cheers,

Bob
 
Favorite tool in my box, the bent 1/2".

Hmm, interesting. I am sure I have at least one or two cheap 1/2" wrenches lying in the bottom of my tool chest. Perhaps with a bench-vice and a hammer I can fabricate something that will do just the trick.

BTW, have I under-estimated replacing this gasket in 15 minutes?

Thanks

Bob
 
You can't do anything in 15 minutes. So far it has taken an hour and 10 minutes.
 
This setup works slick!

Oh yeah, you most likely will have to disconnect fuel lines, etc. The link to the camshaft sticks out quite a bit, so you need to move the pump several inches at least.

You'll also want better access to clean up the old gasket (don't want pieces of it left behind inside the pump cavity, to find their way into the crankcase).

And FWIW, I would suggest Hylomar instead of Permatex. Seals better, plus next time you won't have to scrape, and scrape, and chisel, and scrape to get it off cleanly.
 
Thanks,

Good call on the tools, Hylomar and overly optimistic time estimate. I am very methodical. My wife always rolls her eyes when I tell her I'll be in the garage for 15 minutes and come to bed at 1:30am.

I guess I was trying to assess if I could bang this out after work tonight and strike it off my list. Better to wait until Saturday, disconnect the fuel lines and do it right.

given the number of times I have removed the fuel pump on my TR3 and TR4 I am starting to wish I had installed a fuel valve on the line leading into the pump. I think I will next time.

As to your questions, If all goes well half an our would be safe but for me things never go well (in My I started a two wek job on my TR3 and now I don't know if I will be finished by winter). And yes you will have to remove the lines from the pump. I trid doing it without removing the lines and it just did not work.

LOL - been on the receiving end of that eye roll from my wife over this as well..
 
My late wife used to comment that she would much rather I was in the garage, instead of sitting on a bar stool somewhere.
