WIX 33040 In-Line Fuel Filter Replacement Compatible with American Motors (76-83), Buick (63-66), Jeep (72-90)

Love Wix filters, they always perform well. Filter fit great on my 87 Jeep Wrangler with a 4.2L

Good quality I’ve bought two in the past year, they lasted good while up to 30,000 miles!

It works

Old cars, carburetors, and heat are not a good combination. Unfortunately the gas today boils at a much lower temperature than it did just a few years ago. This is not an issue with fuel injection however, if you’re running a carburetor at 3 to 6 PSI and a mechanical fuel pump, then vapor lock sometimes happens due to heat (when the fuel in the fuel line or fuel pump actually start to boil) Causing an air gap between fuel pump and the carburetor. Ultimately the car will stop running, this fuel filter has a great smaller diameter secondary line that you can use to run a return line to your gas tank. If ran correctly, this will allow the pressurized fuel vapor A place to go back to the fuel tank, Allowing the actual fuel to flow from the fuel pump to the carburetor. This is a great solution for people that drive mostly stock 50s and 60s cars with today’s fuel.

Perfect if you need a return Back in

For anyone having trouble getting both hoses and clamps on this, make sure you're using 1/4" for the vapor line, and 5/16" for the fuel line.

WIX is rather synonymous with filters. Since ethanol fuel became standard at the pump, on older carbureted vehicles, heat soak and vapor lock became an issue in warm weather. Did I say alcohol in fuel was a bad idea? In other words, your vehicle can run fine until you shut off the engine, let it set ten minutes, and find that it won't restart. You can insulate metal fuel lines to help. A phenolic spacer under the carburetor to keep heat from being transferred to the carburetor really helps. But, the one trick that does seem to work is by using this type of fuel filter, with a third smaller spout to return fuel pressure to the gas tank. This requires some plumbing, but if you are messing with this, you can probably do the installation. So, the pressure that would build up, displacing the fuel trying to get to the carburetor, is now relieved and fuel can flow. It's actually a pretty cheap fix.

return line allows cooler fuel to make it's way to the carburetor rather than high pressure vapor pushing fuelout of carb and floodingintake manifold this filter solved our vapor lock in our 1929 chev engine

What's not to like here . WIX brand filter the best . A return line so the gas dont vapor lock any more . Cause with the lower grade gas we use now a days with ethanol just boils faster. So it's kind of a must with older carb cars . Hit the helpful button and let me know its help thanks.

thank you

Works perfect

Exact match for my 1989 Jeep Wrangler YJ 4.2L AMC 258 I-6, fitted with factory 2 Barrel Carter BBD.
