IMO- the closer to the carb the filter is, the better.6426yy said:Does it matter if the filter is before the fuel pump (Mechanical).
?????????????? How does a Fuel Pump generate any Crap,..???????Junk coming from the tank won't hurt the mechanical pump, but the pump itself might generate junk that you don't want getting into the carb.
The diaphragm is rubber. Rubber deteriorates.bondo said:How does a Fuel Pump generate any Crap
It doesn't much matter how, the fact is, "junk" does enter the fuel system. With cars as old as many hot rods are, there's no way the tank's gonna stay perfectly clean. If not from a deteriorating tank, then from the lines, fittings, repair work, etc. that will eventually introduce "junk" into the fuel system- it is not a closed system, after all.alittle1 said:How are all you guys getting 'JUNK' in your tank?
You are assuming that the franchise's proprietor is changing out those $10-$20-a-pop filters as per the recommended schedule. Good luck w/that! If they're even installed in the first place.Most 'good' service stations have a filter on their delivery hose to remove any debris before it gets to your tank.
Methanol 10% is de facto in FL and GA as well as other areas- there's not much in the way of choice. The gas stations are allowed to do this- and none in my area say they don't- so the assumption can be made that they do. With this alky comes water, as well. If this sits long enough, the alky evaps and the water is left behind.you do something stupid, like put methanol in with your fuel.
Thats the problem with ethanol being added to gasoline is that it harms the equipment. Rust in steel tanks causes scale to get sucked into the fuel pump. I would rather deal with two filters and be save than one and get stuck or worse.alittle1 said:How are all you guys getting 'JUNK' in your tank?
They wouldn't even be allowed to race at an NHRA or IHRA sanctioned event. One quick way to see past the BS if they are telling you how they trophied at this or that event.streetrodderbn said:I see poeple everyday that have the plastic filters with great expanses of rubber hose under hood with the filter strapped or zip tied to the front of the engine-YIKES!!ain: Safety first!!
I have seen several small surface area fuel filters plugged with trash.alittle1 said:How are all you guys getting 'JUNK' in your tank? Where do you buy your fuel, at the pick a part fuel depot!
