Hi, I am repowering my 68 MK 1 with a 99 laser 1840/5 speed DOHC 16 valve , and need a return line to tank for the injection.
I figure I will add the line into the sender plate.
But having a look, it almost seems crimped over, I got it to turn a little to see if when the 3 cutouts line up, it may come out.
But am fearing causing a spark, it is a bit daunting with your head in the boot over a tank of fuel hitting it.
Any info?
Before I drop whole tank out to have a better look.

Hello, Pooch, welcome aboard. Sounds like an interesting project. What engine are we talking about here? We've had a few interesting ones over the years - Rover V8s, Perkins diesels, Toyota, VW VR and the like - but I don't recognise your designation. We know "B" and "E6"...  The fuel sender is retained by a brass camlock ring. Get it clean, get it dosed in penetrating fluid and tap the lugs gently and repeatedly in turn (anti-clockwise I think) and it should just pop off. Being brass, it won't be corroded in place, but will be filthy, so sticky. Curiously enough, we had a member recently who bought a car with an unexplained hole in the filler neck of the tank. It's history suggested that at one time it had had a diesel, so needed a return line. Also, forum member Snoopy11 has an injection "B" engine, so that runs a return line to somewhere. Hopefully, he might see this and tell you where it went! Pictures and build threads are always welcome. Chris. |

Thanks Chris, I did find a thread saying the 1800 was similar to MGA, and I found a MGA utube video, and got it out easily.
Not sure what B and E6 is.
99 Ford laser/mazda 323 same car.
Will post some pics when I get a new phone after busting mine.

Morning, Pooch.
The "B" engine was the 1500, 1622 and 1800 unit used by BMC through the 50s, 60s and into the 70s. It went into just about every medium sized car, most notably the Oxford/Cambridge series, MGBs and Marinas before finishing up in the Princess and Sherpa. It's a simple and rugged engine, but perhaps a little crude with its persistent incontinence problems.
The "E" engines were a serious attempt at replacing the "B" and a first try at "modular" thinking by BMC/BL. The E4 went into Maxis and Allegros; the E6 into the 2200 and Wolseley Six before ending it's life in the Princess range. Not terribly popular due to its longish stroke which meant it wasn't particularly free-revving.
Did a bit of Googling about the Mazda motor. Parkers said:
Sounds like a decent choice. I'll be interested to see how this develops.

The fuel return to the tank on my car is simply via a piece of copper pipe fitted into the filler neck of the tank. The hole was carefully drilled with a slow drill and a 90 degree drill attachment through the hand hole in the boot. Pipe was fixed into place using the chemical weld putty stuff. A rag in the neck was also used to stop any swarf from the drilling going into the tank. Slow drill to eliminate risk of heat and sparks.

I ended up drilling and fitting a return in the sender plate, did not like making any sparks with my head in the boot over the tank while smelling fuel fumes. Have another Q. I assume PBR is the booster? Where is this light and switch?  |

Hello Pooch.
UK production cars used Girling equipment for the brakes and clutch. Oz cars used PBR equipment as part of the local product content requirement from the government. The Girling cars don't have any switch gear associated with the brake servo (booster), so I can't tell you what it's for or where they'll be situated.
1800heap and Alpinelandcrab are Oz members. With a bit of luck they may be able to pick this up and help.
I do have an Oz workshop manual at home (We're away in Cornwall at the moment), so I'll have a look when I get back and see if there's any info to be had.
Chris.

Many Mk1 Oz cars in fact used the UK made Girling brake and clutch components. Not sure of the changeover date when there was a requirement for a percentage of locally produced items, you would need to check what is actually fitted to your car. I believe the PBR servo only operated on the front disk brakes and the limiting valve was omitted.
The warning light may possibly be something to do with the alternator if it has an external (PBR) voltage regulator as some did back in 1968 - just a guess.

I haven't seen anything like this on my oz mk11. I have seen it with dial circuit brakes on a Triumph. Not PBR but may be the same idea. It was a pressure differential valve. When one of the brake circuits fail, the valve senses the pressure differental, the switch clicks over and shows a brake warning light. They are a pain for bleeding the brakes and not that easy to reset! There is no mention of such a valve in the Oz crab WM that I can see. Can't think of anything else.
