71_Bronco 1,072 #1 Posted October 4, 2018 Okay, couple questions here. First is regarding my K321 I'm working on. It has the stock aluminum housing mechanical fuel pump on it. How do I check it to make sure it is working properly? Put my fingers over the nipples and see if I can feel suction / pressure as I turn over the motor by hand? Or should i just take it apart and give it a good cleaning for good measure? Second is regarding filters. What is a good source / brand / style for an in-line fuel filter? Third, how about an in-line shut-off? Are the Brigs & Straton plastic ones from Home Depot any good? And lastly, what about the fuel tubing itself? Has anybody used clear tubing rather than the black stuff to see the fuel in the system? 1 Share this post Link to post Share on other sites
oliver2-44 8,951 #2 Posted October 4, 2018 Good questions, and I'm interested in the reply. Especially any fuel line that is ethanol resistant. Share this post Link to post Share on other sites
pfrederi 17,206 #3 Posted October 4, 2018 (edited) you are not going to feel much of anything turning engine over by hand. if you open it up you will probably wind up needing a kit. There isn't really much to clean. I would wait until you can spin the engine with the starter and see if it pumps gas. Clear plastic paper filers 1/4" are all you need.. i use the red handled no name shutoffs with out a problem. I bough a roll of tygon can't really speak to longevity yet.

ebinmaine 63,696 #4 Posted October 6, 2018 Plus 1 for the tygon idea. I use fuel line I can see through. Either tygon (yellow) or the clear/blue available from parts stores or a - z.... Share this post Link to post Share on other sites
