If one mistakingly reverse the return line and the fuel line will it ruin the fuel pressure regulator. Also does the ECU have to screwed to the bracket to make a ground and will this cause it not to start? Thanks for any help:

I am restoring a 280z that I bought new in 1975. Doses the low build number make it worth more?

Putting in a 76 water temperature switch in a 75 280z. The new switch has a male and female adapter. Can someone tell me which is the neg or positive?

Received a new water temperature switch to put on my 75 z. Can some one tell me which wire is the ground by telling me if it is the male or female end?

Need to replace this switch. The ones I get have 2 tits coming out the front and the switch is too big to to fit in were the old one came out. The one I am trying to replace has 2 wire coming out of the switch and the inside is concaved. Does anyone have one for sale or know where I can find on

Thanks for the info. No your not losing your my I am new at getting around the site. I am a real ideiot (can't even spell that). Thanks everone for the help. I'll try to limit my post.

Can someone tell me what connects to the dist vac on the canister and what connects on the purge line. I have the purge line connected to the intake manifoled. The only one I can tell is the fuel.:

Years back datsun tech. told me that 75 ecu was made by Bosch and after that they were made by Hitachi. My75 yr datsun was unit #1249

Yes I clean the gas tank. Would the excess pressure cause the injectors not to work? Yes it has as a regulator. Does the fuel circulate through the fuel rail and when the the pressure get high then the regulator opens and let some fuel back to the tank?:stupid:

Purchase 280Z that sat 10 years. Replace the fuel pump and fuel filter. Have fuel up to the fuel rail but won't start. Seems that the fuel system pressures up so much that the fuel pump seems to squeal. Does anyone have any ideas?
