Nocnir Posted March 10, 2017 Report Share Posted March 10, 2017 Hey guys. So the lever in my mechanical fuel pump keeps collapsing. I uninstall the fuel pump put the lever back on and it just collapses when I turn the car on. Any ideas why it does that? Is it broken? Pump is not that old probably going to be a year since I replaced it. 1972 Datsun 510 stock Thanks. Quote Link to comment
Ranman72 Posted March 10, 2017 Report Share Posted March 10, 2017 what do you mean by collapsing and how did this start since it seems it was at one time working properly they have a spring that should be constantly pushing pressure on the cam lobe is it possibly broken or dislodged 1 Quote Link to comment
Draker Posted March 10, 2017 Report Share Posted March 10, 2017 It's probably a cheap aftermarket pump. I think I've heard other people have this issue. Does the pump have 4 or 6 bolts on the top? 1 Quote Link to comment
wayno Posted March 10, 2017 Report Share Posted March 10, 2017 I wonder if the spacer was forgotten when the pump was replaced. 3 Quote Link to comment
Nocnir Posted March 10, 2017 Author Report Share Posted March 10, 2017 Well it keeps coming out of place so it's just loose in the inside. The spring is there and the fuel pump does have a spacer. I was driving when it happened it just stopped delivering the fuel and the car turned off on me. I uninstalled it and the the metal parts on the sides of the lever where out of the slots. My fuel pump does not have any bolts on the top. Quote Link to comment
wayno Posted March 10, 2017 Report Share Posted March 10, 2017 I have not heard a lot of good about them aftermarket fuel pumps, but whatever keeps the Datsun on the road. Quote Link to comment
banzai510(hainz) Posted March 10, 2017 Report Share Posted March 10, 2017 get another pump. Aftermarket ones are 30 $. I prefer the Koyosan ones myself but alot of money now Quote Link to comment
Draker Posted March 10, 2017 Report Share Posted March 10, 2017 You can get a NOS pump still for about $80 or so I think. Quote Link to comment

datzenmike Posted March 11, 2017 Report Share Posted March 11, 2017 I thought it was a POS pump. 1 Quote Link to comment
Rick-rat Posted March 11, 2017 Report Share Posted March 11, 2017 How much NOS would a NOS pump pump if a NOS pump could pump NOS ? 2 Quote Link to comment
willz Posted March 11, 2017 Report Share Posted March 11, 2017 NOS = new old stock OEM = original equipment manufacturer TITS = awesome 3 Quote Link to comment
datzenmike Posted March 11, 2017 Report Share Posted March 11, 2017 New Obsolete Stock also. Datsun NOS parts, for all intents and purposes does not exist. Sellers have found that putting NOS in front of a part for sale is the same as putting JDM. Mostly 'knock off' parts from China/Taiwan/Whereever or clean used. 2 Quote Link to comment
