The ABS bulb and fuses are fine (I have started another thread about this). In the process of giving things a look over I noticed that there has been a leak on the top of the ABS pump. Looks like I didn't tighten 2 of the lines down properly.

Just read through nearly all of your entire build. Great work getting this far, keep it going strong!

So it's been a while.

I found out that my coolant setup wasn't quite right. Ihad a valved cap in my rad which meant when the water from the howe tank came down, it couldn't get in to the rad.

I couldn't find a high enough pressure cap that wasn't valved, and I didn't want to go through the hassle of getting my rad welded, so I did this:







Tried to get it MOTd again, but because of the coolant leak, the brakes need bleeding again and the bucking is pretty severe, I cancelled.

Next stop is to book it in for a tune.

I did get RB dual tip exhaust though. I am taking welding lessons at the mo so I am hoping that I can ditch the exhaust I got made, and repurpose the Hinson y-pipe and join it to the RB backbox.

Just realised that I didn't update the abs light issue.

Its now sorted, I had 2 pins switched the wrong way in one of the connectors. Unfortunately I had to take the dash out to find where the problem was.

Its done and back together bow though.

Been very lazy recently, but got myself a few things:

It was bugging me that I didn't have a check valve for the fuel pump so I got this. I've ye to fit it but it looks like it may give me a few problems to solve as it is way bigger than I expected.


I also got a pair of 3" cats. This is a bit premature as I have barely done any Tig welding yet, but I thought I would get them whilst they were discounted


As for the rest of the car I have had some 10mm spacers made in an attempt to fit the stock strut bar. Nearly there with this but needs some fine tuning (I think it is slightly touching the intake).

In terms of getting the thing on the road, I need to sort the bucking. My plan now is to jack up the rear of the car and see if I can recreate the bucking at low speed and under no load. If I can then I will have a tinker with the timing and/or AFR to see if I can get it to a point where it's driveable.

Oh...I also spent ages relinking all my thread images. Thanks Photobucket.

Some pics of the strut bar. It's still pretty close, maybe 3-4mm between the strut and the intake. This could be increased by bending them mounting points some more.






As predicted, the check valve is too long to allow me to run the hose barbs. I will have to see if I can get an extended female-female fitting or use a standard joiner and move the pump a little higher up in the tank.

I wonder if Swagelok would have an adapter that could help out in fitting the check valve?
The nice part about their compression fittings is the easy length adjustment.

Another option could be to use AN flare nuts and flare a short piece of stainless tubing to the specific length you need.  The hard part may be finding a 37 degree flare tool, but I'm sure they're out there.

I did look at flare nuts but I think the fittings are too close together. I don't think there would be enough room to flare the tube. There's only 50mm from the base of each of the fittings.

Here is a very short f-f JIC hydraulic fitting , its plated steel but is 37* the same as AN.  http://www.universalhoseandfittings.com/product_p/fjx-fjx.htm   
You should be able to find a hydraulic outlet in GB that has this fitting.

This is my solution for the fuel pump joiner. It's 12mm longer than I wanted, but hopefully isn't too long.

Well that didn't work. It was 5mm too long. Plan B is to raise the bulkhead fitting up so that the bottom of the AN fitting is flush against the bottom of the hat. This won't be massively secure as there will be nothing clamping the hat from the underside.
