TR2/3/3A 1960 TR3A w/TR4 engine, fuel pump replacement

[kodanja]

I have a 1960 TR3a with a TR4 engine,
I am about to change the fuel pump,
any tips would be appreciated...
seems the steering column may be in the way,
or do I need to do the replacement from the bottom up?

I've always replaced them from the top. The aft retaining nut can be a challenge. I have a "special wrench' that helps with that. Just make sure the cam follower rests on top of the cam.

 

[kodanja]

others are saying the steering column needs to be removed for access to the pump'

 

[bobhustead]

"Others" are mistaken.

On my 1961 TR3 I cut the corner off the steering column bracket so I could get my fuel pump on. And I go in from the top. I use "flex" socket extension.

 

[mastaphixa]

It sounds like the support bracket for the two piece steering column presents obstacles that the single piece column does not. Mine is a single piece column but I have replaced one on my friends car and its a two piece without cutting anything. I remember it was a challenge, hence my special wrench, but still doable.

A 1/4 in wobble with a short 13mm socket, on a 3 inch extension.Doubt if I have done
more than 50 over the years. Dont even start if you do not have these tools in hand.....

My two cents worth...
Buy a block off plate and ditch the old mechanical fuel pump and get a Carter electric fuel pump and mount it under the fuel tank on the spare tire well. It puts out 2-4 PSI fuel pressure and you'll never have a fuel pump issue again. Works like a champ on my car

Absolutely go with an electric pump. Did that years ago and never had any problems. So many people are having problems with the stock pump when this is the solution. The argument that you want to keep it original is not worth the hassle. Look at the inadequate stock radiator fan , it is replaced by an electric fan by many since it is an efficient and practical upgrade. Same thing with the pump. My .02

The original FACTORY fuel pump was as trouble free as a summers day. But I understand
in this age crappy AM bits why many folks prefer electric. If you install an electric pump, it is
absolutely vital to fit a GOOD quality regulator. 2.5 LBs is what SU crabs need to work well and
NOT waste a bunch of fuel. Word.

I've been running the fuel pump on my car for many years without a regulator. The pump must have been a 2.5 psi pump?

Being in a local British Car Club we get a variety of cars on our rides. I can recall of 4 times when somebody had a fuel pump problem every time they had an electric pump. One was on a TR3 where it had been converted to an electric pump. My offer of a temporary mechanical pump was no help and it was in a small town on Sunday so no auto parts stores were open to replace the electric pump.
The only problem with a mechanical pump was on a TR6 where the pivot pin was working loose. This a modern reproduction.
I am sticking with the original mechanical pumps that I rebuild.

Karl ,I will bet that you have wasted a lot of gas over the years.Buy a GOOD fuel pressure regulator
and report back when you can compare mileages.

A good elec huco pump works fine in a tr3 with su’s without a regulator.
it won’t provide more pressure than the carb floats can shut off.
i only went to filtered regulator with a facet pump and twin 45 webers.

 

[kodanja]

Im running stock SU's, im going to stick with the original manual fuel pump, its served very well for the past 63 years with no upgrades

And I would have gifted you 2 two inch Jag SU"s which bolt onto the OE manifold(nasty Webbers).

I am in the mechanical pump is fine camp. I have owned lots of Triumphs and MGs and Austin Healeys. I have had a lot more trouble with the electric pumps in the MGs and AHs than the Mechanical pumps in my TRs. The current TR250 pump was rebuilt with the rest of the car 15 years ago and still works fine.

And the trouble I have stopping leaks and keeping the webers balanced I would would have tried the big su’s !!!

Well you do have to work the splitter on the intake pretty good, but the MGB E-prod guys
used these a LOT.(in the day).
They are just sitting here ....

Just out of curiosity...... would putting 2" SU's on a TR3 with a mild street cam and header make the motor over carburetered ? What would happen?
