Hi I'm new to the forum and this is my first posting. Apologies if this has been asked before.
I'm restoring a 1960 BT7 and I've been looking for photos of the correct fuel pipe routing and wring for the fuel pump around the axle.
I looked at a mate's BT7 but his is from 1959 and has the fuel pump on the left hand side nearer the exhaust. Mine is on the right hand side and hopefully I've got the correct bracket and pump? -see photo.
The wiring loom I bought is clearly for a car with a left hand fuel pump as the wire's too short.
I've attached a photo looking through the rear tractor seat base - it looks a bit odd because the car is on its side on a rotisserie.
Grateful for any images that could shed some light on this.

According to the "Original Austin Healey" by Anders Ditlev Clausager, the fuel pump was moved from the left-hand side to the right-hand side at car numbers BT7/17352 and BN7/17547 in January 1962. and the pump spec changed to AUA173.
If yours is earlier than those car numbers/date, the left side would be correct and therefore the wiring harness you have is correct. Mine is a Sept '59 build BT7 and it's on the left side. The fuel line runs down the lower inside of the left frame tube
The book also says they made the change "to avoid vaporization due to exhaust heat". I've never had a vaporization problem, but if you have, an argument may be made for re-locating it to the right side as you have it unless you are going for concours,
I don't have much in the way of pictures of the line routing doen the left frame but I've attached 2 that may help.

Guys
Thanks for the replies.
The car is LHD came out of Florida, built April 1960. The rear heal board has the captive nuts for the pump bracket on the RHS but it just occurred to me that this is a replacement panel [bought from Kilmartin in Australia] and is maybe for a later car. The original heal boards were missing when I got the car. See photo.
That answers my question thanks. Now I just have to decide whether to move the pump or not.

Nick,
It's an Accusump oil accumulator (remote oil filter is hidden just behind it). Not really needed on a street car but I had it left over from my 100-6 race car so decided to use it. The nice feature in a street car is that, with the electric valve, it captures oil under pressure when you turn the key off. The next time you turn the key on oil is released and you see oil pressure on the gauge before hitting the start button - never a dry start and theoretically bearings last forever.....
