    Do you have a DIY vacuum / pressure tester?

    Not DIY but I’ve bought both a pressure and vacuum tester a few years ago and am using it now to check for leaks in my old fuel line/fuel pick up tube….

    Fuel starvation conundrum

    Ya and yes. My QJet just has a screen in the fuel inlet that was replaced when I rebuilt it this summer. Gonna do a pressure test and see what that shows.

    Fuel starvation conundrum

    Update: vacuum test didn't hold over time but I'm not sure that's such a valid test. I am going to do a pressure test with soapy water to see if there are any leaks in the tube, anti siphon valve and old fuel line. for testing the fuel, I think I'll siphon out a gallon or 2 and see how it runs...

    Fuel starvation conundrum

    I think the same thing happens to automotive OEMs with their suppliers. When the OEMs put price pressure on them they look for other sources. I get my stuff from a marine supplier who supplies all the bigger boatyards in my area. Cheaper than West Marine and the guy knows everything! Going to...

    Yep I had done that several years earlier. All the old hoses on this boat are gonna get replaced.

    Fuel starvation conundrum

    Still looking for the smoking gun.... I rigged this up to test the old fuel pick up tube and anti-siphon valve for vacuum leaks, it's holding at -11.5"hg, I left it hooked up in the garage and will go out later to see if it holds or not. A section of the old fuel line is on the end with the...

    an old school radiator thermometer is great for checking a 'stat in a pot of water....I rigged up a length of coat hanger wire to hold the stat and the thermometer off the bottom of the pot....

    Fuel starvation conundrum

    the ones in this boat are dried out & stiff but not crumbling but i do plan to replace them... one last thing I noticed...the ID of the old fuel supply hose to the engine (3/8") seems bigger than on a new section of hose of the same size.....wondering if they could have been sucking in air even...

    Ok I’ll have to smell around again some more!

    Fuel starvation conundrum

    Last question for my iboats friends…anybody know if fuel can be tested to tell if it is still usable or not? Blackstone Labs does offer a test kit but it’s expensive….

    Fuel starvation conundrum

    I replaced the one from the tank to the fuel filter but I know the fill & vent should be done too…thank goodness the tank appears to be in pretty good shape…

    Fuel starvation conundrum

    Good thought! I checked the vent, I think it's clear, who knows with that old fuel line though. I "think" the hoses were original if you can believe. It's a 1988 boat!

    Fuel starvation conundrum

    Thought of that but it ran perfect with the test tank. The use of the test tank reduced the possibilities to: Anti siphon (tested good) Pick up tube ((clean no screen tested good but will do more testing) Fuel line, cut in half to check for delamination found none. Fuel (unknown). Only other...

    Fuel starvation conundrum

    Good suggestions I thought the same thing. Cut the old fuel line in half to check for delamination but found none. The filter, pump & steel lines from pump/filter to carb functioned fine when tested with the remote tank.

    Fuel starvation conundrum

    When I ran the test tank it was hooked to the regular filter so I assumed that filter & the fuel pump were OK. The boat ran absolutely perfect on the test tank. Also I changed the fuel filter after spring start up and dumped the contents into a large mason jar & it was totally clear like it’s...

    Fuel starvation conundrum

    As far as vacuum leaks I had the same idea and tested the old (actually well made) pick up tube, no leaks that I could find. It is all alu with the tube threaded into the top fitting, no screen to clog. Today I will rig up a better way to test it with my vacuum pump. The anti siphon valve was...

    I don’t think much if any would come out if you did that…

    I don’t think your engine has that extra hose that is referenced there.

    Fuel starvation conundrum

    That’s my thought. I may have to get a service to do it for me because it’s about 35 gallons of gas. Gonna ask people I know in the business….

    Fuel starvation conundrum

    Ok so all season had a performance problem where the engine was reluctant to plane the boat and max rpm was way low 3800-4000. First I went thru the ignition system & verified total timing advance, then rebuild the Qjet (but no real problems found). Next ran it on the remote tank with fresh fuel...
