Here is my current fuel system.
![]()
The main tank feeds a surge tank that then feeds a mechanical fuel pump feeding a carb.
The two tanks are vented with a non vented cap to a roll over valve before the fuel vapors move inside the air filter. Not shown is a a pcv valve installed between the roll over valve and air filter which is flipped around to allow vapors into the air filter but closes if there is a backfire.
I want to eventually upgrade this to fitech efi I want it to be october but worst case it will be this time next year.
But for now I am running the carb. Now my fuel tank has a pump in it but that thing is loud as heck so I am just going to pull through the pump/feed line to a external pump after a filter of course.
I am looking at using this pump

I have continuous aluminum line that run from the pump to the surge tank. I have some high pressure fuel hose (rated 225psi or 250 its over 200 for sure). That will connect the tank, filter, pump, and surge tank inlets barb fittings. No messing with trying to flare things.
The pump will run unrestricted. But I like to over build on stuff that can catch me on fire.
A loss of oil pressure will shut off the main pump and eventually a second pump.
The pump above can maintain a easy 70+psi and outflow anything that I will need for the fitech which has a recommended 58psi requirement so i am good there.
Right now though with the low pressure pump I am just going to run a low pressure filter clear filter 20 micron and throw it out when it starts to yellow or at 6 months(usually around 3000-500miles) to kep the carb clean.
The one from the tank to the high pressure pump has me a bit boggled. I want something cheap that I can just pull, and replace every 6 months. They recommend the thing filter 20-40 microns.
I Want the thing to have 3/8 barb fittings so I can to just slide some new hose over the thing when replacing it and avoid creating 2 more possible leak points if I was to use 2 an/barb fittings adapters.
I am open to rebuild able ones. But with the cost of those ranging from 30-80 and higher I am in the grey area wondering what I should go with.
The roll over valve is from coyote and both fuel pumps local. But the stuff like the brass fittings and low pressure fuel filter($3 there $12-30 here same part#) are coming from Japan and are showing to arrive around mid February so I need to order the stuff here soon. I want to kick my butt out of the cave in the spring and finish up all the odds and ends on this thing to get it running for summer.
What are you guys running for fuel filters with a pump like this?
Like I said I would like something I could just clamp/cut the old hoses off, throw the filter in the trash, then swap a entire new filter in with barbed ends and new fuel hose. But I am open to rebuilding the thing if it is a better option.
Sorry for the long post. Thank you for any advise.
