Triumph TR6 - Fuel Pump

Sorry for hogging the BBS, and being a wee bit lazy, but while the head is in the the machine shop I am tidying up some of the other bolt-on bits. So my question is "What should the pressure (lbs/sq ft of the fuel pump be"

Many thanks chaps.

unless you have an after market electric which should be about 4 to 6 psi. The mechanical is based on a good spurt every 2 revolutions. If you have the head off its best not to crank due to dirt etc. Watch the carbon on top the pistons if there. Stuff will score the hell out of cylinder walls.

Nobody ever hogs the bbs. Every time you ask a question someone jogs there brain or opens a greasy manual.

How do your cylinder walls look? Any scoring or pitting?

Thanks for the information, I shall probably put an inline electric fuel pump near the tank when I get there.

As for the block the cylinder walls are as smooth as can be (see pic), I did clean off the heads some scum but not caked on.

Unless you have problems with it the mechanical pumps worked great.

Can't see any rust. looks ok. You will need to clean off the block top for new gasket. I always keep the shop vac running to suck up debris as I go. Get an old sheet or plastic to put over so nothing falls in while you wait for the head.

What are you using for torque info for install and what torque wrench?

Les ,unless you are doing something racy with the motor stick with the stock unit. Most of the electrics you will have to run a reg and then you've added a bunch of money

I am using the torque settings from the BL Workshop book, I have a very good quality Mastercraft 250lbs torque wrench. I will be cleaning the top of the block with brake fluid and a very fine emery (unless there is smething better), I have been advised to use the Payen gasket set as opposed to the after market.

Thanks for the info and advice, I guess I will stay stock. One other thing any news if Don Masters will restart?

I hear Dan is still out of touch and dealing with a lot of grief.
Know what it is like to loose a son. Wouldn't wish it on anyone.
