Fitted a pressure gauge to the fuel line going into the fuel rail so we could see if the fuel pressure was dropping off under boost. The pressure is suppose to follow the boost but as it turns out it did this to a point then starting dropping off which is bad.....
The pump I have is a DA-27 which should do 305lph. Something wasn't right with the pump anyway as it seemed to have a leak and the internal part of the pump turned around inside the outer case which the guy I bought it from said shouldn't happen.
I bought the pump from eBay for a good price, they have had good write ups so was worth a go. The seller has been an absolute star and his communication is spot on. After a bit of a chat he said there is no probs returning the pump for a replacement so after a bit of thought I have decided to go for the bigger pump (DA-31) as this has the same threaded ends as a Bosch 044 pump and the push fit ends Bill is getting made up fit this type of pump. Bill had got one in as a test so I swapped mine out with this one as the prototype push fit fuel pump ends had turned up.

Here are some pics of the pump and it fittings...
Fitted in place of the fuel filter...
...in comparison the previous pump fitting...
Started the car to check for leaks while the car was on the ramp and Bill noticed the pump was very quite... could hear a whirring and sounded like it was coming from the pump but putting a meter on the terminals said different.. no actual power to the pump. Checked the connections inthe car and one of the wires had come out of the crimp terminal where I spliced into the OEM fuel pump wiring DOH!!! no idea if this was like this from the start... sure when we fired her up for the first time it was working... anyhoo, working now and plenty of fuel pressure too so cured all sorts in the end... result!!
Checked for leaks and looked at the driveshaft gaiter to see if there is any probs... the water pipe from the turbo to the block has developed a small leak. Not enough to take the car off the road but it needs fixing as soon as I can. Think I will get a pipe made up from Bill's 'Pipe Guy'.
The driveshaft gaiter is still in one piece however, there is a distinct shiny wear patch on the last bit of the gaiter (not flange end, shaft end) which means at some point I am gonna have to remove it all and 'adjust' the downpipe a bit. Might see if I can loosen the v-band and move the DP up a bit on the turbine housing to give a little more clearance before resorting to other means.
Having a problem keeping the boost below 2.5bar too... ok as a spike but it holds under certain conditions and the map is dialled in for 1.7bar so a manual boost control may be needed.
Fuelling is still a bit out but to be fair the last map was tweaked to take the original fuelling issue into consideration so its over fuelling a bit now.
Few things to iron out but getting there. Actually got a chance to stick the boot in and she flys!!! bit more to come with map tweakage and then some added timing advance.
