Just wondered what the best way of fitting the fuel gauge into the tank is, is it just a case of rivnuts and bolts?? or is their a better way?

ta,
Rich.

Mine was an MG midget sender with an extended arm(soldered welding rod!!), fitted with self tappers into the top of my mild steel tank with a cork gasket..........

Hi Dave,

I was going to use self tappers but thought that was too simple!! maybe I'm looking to complicate things too much!

It has a rubber seal so in hindsight self tappers are probably better then rivnuts.

thanks for the help.

Rich.

If you use a sealer ,( silicone etc) be very careful, I found that the ends of self tappers take a blob of silicone through with them, then it drops off at a later date blocking the fuel line at regular intervals..............v.annoying...............

I tapped out the holes used little cap heads with a rubber gasket.
As Dave says, use a proper petrol resistant jointing paste not silicon, it turns to snot....

Hylomar or Loctite instant gasket for petrol gasket goo. If you want to use silicone to form a gasket put it in place and let it set before you put the surfaces together.

While we're on tanks...
I've got an MK aluminium tank but there's no hole for the sender unit.
I can't find anything like a long+tall+thin level-sensor that can fit down inside the filler pipe and is compatible with the Sierra gauge -
So we come back to breaching the tank for a regular sender. There are two problems here...
1. I don't know if there are baffles in the tank and if so, where
2. I'm paranoid about leaving swarf inside if I use a regular tank-cutter.

Any ideas?

I cut my tank for the standard sierra sender ( Ive got a template if any body wants it) just washed it out loads of times, if youve got a filter in the line it should be OK.

Ninja,

Wouldn't mind a template for the sender, do you have something you could email?

Cheers

Good point I didn't think about whether there are any baffles, I don't think so but I'll check with MK in the morning and post on here.

Rich.

When looking from the rear there is a baffle about 2 inches from the left hand side of the tank. If you look closely on the front and rear you can probably see a couple of weld marks.

I believe that the idea with the MK tank is that the pipe on the left (within the baffle space) is the fuel pickup pipe. This may be blocked off in case people want to make other arrangements for fuel pickup.

Thinking about it it could be the breater pipe on the right that's blocked off.

In any case, al that's needed is to run a drill through it then clean it out.

As MK Ninja says, rinse it out and fit a fuel filter so you can see any crud that pops out from time to time.

The template is on Autocad, I can Email you that or print it out and put it in the post, just let me know.
