Hello mate,
I think Ben says it was gx390 20 or 21 lpm, am not 100%, it is 220 bar. I had mine built on a plate so I can bolt it down in van, it can also come off the plate, but I was thinking of have another plate made so I can fit it to the top of a water tote.
I wish I had gone for the electric start, it was a bit more but it's a nightmare some mornings with pull start, I was advised to get this but am all about cutting corners to save on cost.
He started off with a gx390 and I told him what I wanted even against some of his advise, I also got quick release fitting and 2 x 25m hose, really good quality, these are very heavy so maybe think about 10m hose, I will be getting one next week.
I don't know nothing other than it starts and does the job no bother but I think Chris says which pump to ask for, I will send you picture to email tomora.
Ben has been in touch since the sale and I have called him when am not sure of things, I can't say a bad word about him, nice helpful guy.
I will find the bill as the wife transferred payment so am not sure what final bill was.
