Wedge List / Coolant inspection sight glass?
« Last post by Odd Hedberg on July 15, 2018, 12:43:50 PM »
I know we got wind of an inspection sight glass for the upper radiator

hose some time back, and I am sure I stored the URL - but now I can't

find it.  Istr it also had an air bleed valve so as to get that pesky

last air pocked in the upper radiator hose out.

Anyone have the info left?

Think you will find that whilst there is air in the system the hole is open

but when the air has gone the jiggle pin floats up to block the hole.
Wedge List / Why the jiggle pin?
« Last post by Odd Hedberg on July 15, 2018, 12:38:46 PM »

my neighbour and I were to change out the coolant thermostat in my '8

today - and suddenly he asked me a question I had never thought before:

"Why that little jiggle pin, why not just the small bleed hole?" I had

to answer "I have no idea - they're always there. But why that is better

than just a hole I'll have to investigate..."

So, why is the pin there?  What's it doing better than just the plain

hole?  Seems to be some sort of check valve function maybe.

Wedge List / ?? Large Nipple Under DS Carb - V8-Stromberg Coolant Hose
« Last post by Bill on July 14, 2018, 03:22:15 PM »

There is a large nipple under the drivers side carb that looks like it

passes coolant into the manifold to heat the carbs.B  Any issue with

bypassing & blocking this off?B  They don't need any more heat.B  Water

can still flow through the water chokes if routed to the overflow tank

as normal.

Also there is a vacuum nipple coming out of the carb base within an inch

of the water nipple.B  I what is that used for?B  I have been pulling the

vacuum advance off the ports at the top of the carb...

I have Stag and I think the AC compressor that you mentioned is the same

type.  My AC doesn't work. The compressor and mounting bracket are missing.

I don't plan to get he AC working, but it would be nice to have a

compressor for it. I've heard they are heavy and people seem to swap them

out and use a Sanden manufactured compressor instead. So this may be a

prohibitive cost to ship one to the US. Do you have a mounting bracket for


I'm in California.

Wedge List / Bonnet Badge 1980 & Later Cars

Having reproduced 55 stickers and labels (17 emission labels for TR7 and TR8

alone!) I have now had a request for a much more substantial project.

The original XKC3902 badges as used on later TR7 and TR8s made at the Solihull

plant have not been available for many years.  The original badge maker is no

longer trading, but I am in discussions with a manufacturer in Birmingham that

has been making badges since the 19th century.  As with all these ventures,

economies of scale are present, but at around $100 a badge for 20 falling to

around $75 a badge for 100 any outlay is considerable.  I am trying to gauge

numbers (if 30 people would commit to 2 each then 100 is on the cards at

once!) and how much people would be prepared to pay.

Please respond directly to me (only once as I will be asking on other forums!)

with number of badges you (might) want at $75 and if they were $100 (plus

shipping etc).

Wedge List / Re: TR8 auxiliary in-line fuel pump?
« Last post by mark Elbers on July 10, 2018, 09:46:11 AM »
Regarding pump failure,   I think there are those on the list that have done

it in the past, but it depends a little on the failure mode.  If the hoses are

somehow plugged or have perished due the ethanol  content  of the fuel etc..

your success rate may vary.

The nice thing about carbs is the float bowl, which acts as a buffer, so the

fuel pump doesnbt need to be supper high pressure and always on like the

EFI,  where any interruption will kill the engine.  I used to have a pump kill

switch and I noticed the engine would run for a block or so after turning the

pump off. A useful anti theft device.

It would not hurt to have a spare external pump and filter assembly in the

bGOb bag though.

As for increasing pressure,  what scenario would require this mod?  Increase

flow I could see for certain engine mods,  but pressure increases might cause

problems with the float valve.

Yes and yes.  Been there, done that.

I played with the idea of mounting two external pumps in parallel with a change-over switch just to have redundant pumps.  That was the result of fighting pump problems on an extended road trip.

That presumes that the pump failed for reasons other than it is clogged with rust particles.  If the intake is clogged an external pump will not be able to overcome that.
