I hope I am not to late to help anyone with this. But I was about to swap the diaphram over to my old pump but noticed that the diaphram in the new pump was shaped a little different than in the ampco pump diaphram i was replacing so instead of risking a leaking pump i replaced it completely. Also if i could say to Vital Parts. The ampco pump that was originally on my 260Z did have the donut shape diaphram rod. Although I have now put on the new pump and every thing seems to be working as it should be I am hoping I can get the repair kit for my old ampco pump with the view of putting it back on to bring it back to its original condition. Hope this helps. Kind regards to all zedders.

Hi Gav.Thanks for the advice.The new pump that I bought from (aladdin.com ) only had the philips head and no slot for flat bladed screw drivers.However I am glad to say I managed to strip it down an swap over the innards into my original pump which happened to be a "ampco" pump.I have yet to fit it and try it which I will do tomorrow. Will keep you all informed on this site. All the best for 2017.

Really love this site. So much advice,its great.

Hi Zup.You are congatulating me to soon. I gave it 4 or 5 attempts bit it still failed with all new parts so I have now been out and bought afuel pump priming tool. I saw the RAC mechanic use one of these but failed to ask him what it was.Anyway I found one in a shop called Halfords. I have also bought a petrol filter as wel.Tomorrow I will give it another try and will keep you informed as to my progress.

Hi Guys. I am that guy from England again. Tonytomb. I bought a pump from a company called Aladdin.com In the USA it cost about $24.00 but of course I had to pay for postage and packing which is to be expected. I am happy with what I have got but I only change the two upper parts of my pump and left the lower part intact as I did not wish to risk damaging the diaphram and oil seal during the course of dismantling the pumps. Good luck to you all and a healthy and wealthy 2017.

Hi again. I have now purchased a simialer brand new pump on ebay from the USA. I hope the internals are the same as the ones on mine.If so I can swap them around then at least I will have some control over the originalty of my 260Z. The problem I may have is getting out the oil seal unless someone can give me advice on a easy way to remove it,or where I may get a new one probably would be better. Grateful for any help I receive. Kind regards to you all Keep ZZZZZZEding.TonyTomB

What a facinating and informative subject.For a few months now I have been trying to fix my fuel pump which is the "Ampco.G22 Pump" ., coming across this site I have now discovered how to do it. It is sat in pieces on my kitchen window sill and I have just sent for a simialer pump from the USA.Hopefully the diaphram will be the same as the one that I have taken out of my original pump. I hope that the oil seal is as easy to take out of them both as the diaphram was. I need to keep my 1974 Datsun 260Z 2+2 as original as possible having won many best in class and concourse shows with it.It is totally original and unrestored so originallity is important. May I again thank you for such a fantastic easy to understand article and wish everyone on this site a Very Merry Christmas and the Best of Luck for the coming year. Kind regards.TonyTomB

Hi Zup. I am sending this email from England. The petrol pump on your car looks exactly like the one on mine and after stripping it down I find that I need a new diaphram as the one on mine is perished.My pump is the "Ampco G22". I would be grateful even for the slightest help you could give me. Kind regards.TonyTomB

Hi siteunseen. You may have seen my post to Mr Kerrigan if not I need a diaphram with rod to fit my ampco petrol pump for a 260z 1974. Could you supply me with any leads. Kind regards. Tonytonb

Hi Mr Kerrigan. My pump is the "Ampco G 22 " pump and I need the correct diaphram so I wonder if you could give me the site in Canada where you got your kit from.Thanks for you time. Kind regards.TonytomB

Hi, I know that this is an old subject but having just stripped my pump down I find the diaphram has perished a bit and I am trying to replace it. The diaphram is exactly like the one in the bottom photo on the extreme left. I have obtained the correct material to replace it but can anyone tell me if the diaphram shaft can be unscrewed to fit a new diaphram. I would be grateful for any help I receive. Kind regards.
