Trouty56 565 #1 Posted March 23, 2011 Working with a Charger 10 equipped with a replacement hh100 tuchy (originally was a tuchy also) that does not have a fuel pump. As far as I can see there is not a preset opening to the block to add a vacuum style pump. Firstly, am I missing something, is there a place to acquire vacuum without drilling the block?? Secondly is it feasible to drill and where?? It is a little hilly here and eventually I have to make it back up the hill and gravity, well, doesn't cooperate. :thumbs: Share this post Link to post Share on other sites
Kelly 1,028 #2 Posted March 23, 2011 Some tuckys the fuel pump screws right in where the fuel inlet goes on the carb. they are vacuum pumps. Share this post Link to post Share on other sites

Trouty56 565 #4 Posted March 24, 2011 Kelly, I can get the fuel pump that screws to the carb. Just need to know where to drill for the vacuum connection or is there an opening that I am missing somewhere on the block. :thumbs: Share this post Link to post Share on other sites
Kelly 1,028 #5 Posted March 24, 2011 I 'll look to see if I have any engines with that set up on them, I know sears used that style pump, in the 60's and 70's. Share this post Link to post Share on other sites
perry 82 #6 Posted March 24, 2011 i would not think you should not have to drill anything . i dont remember where they hook up. wait and see what kelly comes up with. or maybe send greg ( pond195520032003 ) the sears guy a PM. Share this post Link to post Share on other sites

racinfool40 202 #9 Posted March 24, 2011 Well I don't know if this will help much but on my 1970 raider 12 it had a drilled and tapped hole directly below the breath cover. Which had a brass nipple screwed into it and had a fuel line hose collar on the other end. Had a 1/4" hose to the pulse style fuel pump. I wish I had pics but the Motor went Ka-Pow about three yrs ago and have since sold all the parts.. I'll do some digging also and see if I can find some pics.. since then I have replaced with a K-301 and have never looked Back!! Might be worth a shoy to PM KB9LOR Brian Innie I know he has a Raider 10 with the tecky maybe he has the set up on his??? :thumbs: Share this post Link to post Share on other sites
racinfool40 202 #10 Posted March 24, 2011 :thumbs: Forgot I had this on the shelf in the garage it's an OH-160 but basically the same set up: I hope this helps..Works good on this motor.. Only tecky I have and runs great Just need something to put it on!!! Share this post Link to post Share on other sites
Trouty56 565 #11 Posted March 24, 2011 Thanks Mike...I dont know how hard it is to drill and tap the block but now I have a place to attempt it at. Might try an electronic one. I have to think about this. :thumbs: Share this post Link to post Share on other sites
