HOGIE Posted November 21, 2016 Author Report Share Posted November 21, 2016 Question, does your fuel pump have a primer lever on it? No but it'd be a lot cooler if it did Quote Link to comment
wayno Posted November 21, 2016 Report Share Posted November 21, 2016 Well you might have to use a low pressure electric fuel pump till you find a stock one for your truck. I have no idea if any other ones are interchangeable like the J13 fuel pump, maybe difrangia knows and will chime in, he knows a lot about these little trucks. Quote Link to comment
HOGIE Posted November 21, 2016 Author Report Share Posted November 21, 2016 I did find a thread on NicoClub written by mklotz70 that talks about J13 fuel pumps and swapping pump arms from stock pump to new 620 or J13 pump. I'll have to read it again http://forums.nicoclub.com/l-series-fuel-pump-on-e1-t375572.html Quote Link to comment

I ran a low pressure electric fuel pump in the engine bay on my Datsun roadster for several years, it was the kind that vibrated all the time but didn't make noise, it worked fine, but I converted over to the U20 engine and removed it as the U20 had a good mechanical pump. Mike has written a lot of articles about 320s, when I bought mine from him they all stopped as he didn't own a 320 anymore. Quote Link to comment
HOGIE Posted November 21, 2016 Author Report Share Posted November 21, 2016 On a different note. My stepmom has a Morris Minor 1000 and I borrowed the engine hand crank and it's just a little to short to be able to grab it enough to really give it a good crank. Did turn it over a few times with it though. My dad told me he could use this as a model to make me one though. Sweet Edit: Here's the Morris for the pic whores 3 Quote Link to comment
wayno Posted November 21, 2016 Report Share Posted November 21, 2016 That looks about right except they don't have the lugnut remover end on them, here is mine. 1 Quote Link to comment
HOGIE Posted November 21, 2016 Author Report Share Posted November 21, 2016 wayno your rod is thicker than my stepmoms I'll just leave that here for now 3 Quote Link to comment
wayno Posted November 21, 2016 Report Share Posted November 21, 2016 OK, I would never try to start my engine with that crank, since are engines are advanced in timing, I would be afraid that it would kick back and hurt me. The model "T" had a start timing position, and a run timing position to keep that from happening, these trucks have starters. 1 Quote Link to comment

Or are you saying you just wouldn't use the one I have? Check out this video. Seems easy. His rod is longer than your. Seems like he can hold onto it between the bumper before the bend. https://youtu.be/upF7M_xvar0 1 Quote Link to comment
HOGIE Posted November 21, 2016 Author Report Share Posted November 21, 2016 Cool ass nl, hogie Thanks Larry. Remember that talk coming back from the rock slide in Central Oregon? I guess it came true 2 Quote Link to comment

Seems easy. His rod is longer than your. Seems like he can hold onto it between the bumper before the bend. I have used it to crank the U320 engine over as that engine had not been run in years and I wanted to make sure it was loose, but I didn't try to start it with it, I would be afraid of getting hurt from a kick back. So that guy is braver than I am, the way the lever is made makes me think it likely will not kick back but kick out, but I will just use the starter myself. I believe that I have an original hand crank as it fits in the holder made for it, but I don't know it for sure. 2 Quote Link to comment
Conner Posted November 21, 2016 Report Share Posted November 21, 2016 Yeah I've used the hand crank to turn my engine to make sure it wasn't seized, but I probably wouldn't use it to start the engine. On the fuel pumps: A stock mechanical J13 fuel pump will swap onto the E-series engine without modification. That was a much more useful piece of information back when J13 fuel pumps were very common, but these days they are pretty hard to find. Swapping the arm off my original pump onto a newer, more common pump, such as the L-series pump (which again are starting to become less common now anyway) was not possible for me. The pin that mounts the arm onto the pump was shot-peened into the pump housing. There are two little steel balls that are too large to press out on either side of the pin. My machine shop was unable to extract the pin without breaking the fuel pump body. My truck came with a J13 Nikki fuel pump installed , and I was able to rebuild it using the internals (basically the identical top half) from a new Datsun F10 fuel pump I found on ebay that had a different arm on it. I think your best bet is to get a rebuild kit for your original fuel pump or try to locate a J13 pump and swap it on. You may need to do some trial and error. Parts from Nikki pumps are more likely to fit other Nikki pumps and the same is true of the Kyosans, so if you do some trial and error make sure you are buying a donor pump that is the same make as yours is. Good luck! 1 Quote Link to comment
Stoffregen Motorsports Posted November 21, 2016 Report Share Posted November 21, 2016 BMC fuel pumps look nearly identical. Morris, Austin Healey, MG, Mini, used BMC A and B series engines. Some of which were equipped with mechanical fuel pumps. Search Google for "BMC mechanical fuel pump" to see all the options out there. 2 Quote Link to comment
Marouk Posted November 21, 2016 Report Share Posted November 21, 2016 I've cranked mine a few times - but make sure you have the saw tooth pulley! Often over the years as the part is replaced, people just slot the front for the crank. If it kicks back you're getting a broken femur or arm. Heaven forbid it hits you in the head... The right pulley has two 'saw' teeth. If it back fires the pulley forces the crank away with the sloped side of the tooth. If that makes sense... 1 Quote Link to comment
Draker Posted November 21, 2016 Report Share Posted November 21, 2016 Post pictures of that fuel pump when you get it out. 1 Quote Link to comment
HOGIE Posted November 22, 2016 Author Report Share Posted November 22, 2016 Post pictures of that fuel pump when you get it out.Yessir The inlet was full of some thick gooey nasty old fuel that looks like the shit used for dabbin. Didn't smell good 2 Quote Link to comment
wayno Posted November 22, 2016 Report Share Posted November 22, 2016 So take it apart, clean it up, and maybe it will work now if the inlet was plugged. Clean it up, stick a hose on it, stick it in a can of gas, and pump it with your hand and see what happens. 1 Quote Link to comment
HOGIE Posted November 22, 2016 Author Report Share Posted November 22, 2016 Im going to try that in a little bit later tonight When I push the arm in and out there is no resistance, zero. When I do the same to the Lseries fuel pump I have, I had to push it against the work bench to get the arm to move 1 Quote Link to comment
Draker Posted November 22, 2016 Report Share Posted November 22, 2016 It's probably all gummed up. Hope you can fix it! 1 Quote Link to comment
HOGIE Posted November 22, 2016 Author Report Share Posted November 22, 2016 Wayno, how does the top cap come off? 1 Quote Link to comment
wayno Posted November 22, 2016 Report Share Posted November 22, 2016 If it cannot even get air there would not be any more resistance than the spring for the arm, once it gets fluid it will resist if it is any good. 1 Quote Link to comment

wayno Posted November 22, 2016 Report Share Posted November 22, 2016 Wayno, how does the top cap come off? You have to take the screws out to pull it apart, not sure what that nut does on top as I have never had one apart. 1 Quote Link to comment
