WIX Filters - 33040 Fuel (Complete In-Line) Filter, Pack of 1

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

Fit and work well on my Jeep CJ 7. Good seller,

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.

Fit perfectly for my CJ7, good price

This vapor separation filter was the fix for the fuel percolation problem I encountered. Fuel was boiling in the fuel pump, causing bubbles to go up into the primary float bowl. The spitting of fuel caused by the bubbles caused gas to spray out of the float bowl vent into the carburetor throats and stalled the engine. This filter, along with running a return line to the gas tank via a new sending unit that had a 1/4 inch port, purchased on Amazon, cured the problem and now there is no stalling with either winter or summer blend fuel. It will be easy to change out when replacement is needed, now that all the lines are in place. It helped make for a relatively inexpensive fix to a stubborn and baffling problem.

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.

Good little filter.

Great Specialty Filter from Wix. Always a quality product.

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

Works perfect

thank you

used it on my fuel line by carb, it was vapor locking, it fixed my problem. car runs good now.

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.
