Who has added an in-line Fuel Pump Check Valve?

Who has added a inline fuel pump check valve? where did you get it? I already installed a new Airtex pump (whole assembly) but with my luck the fuel pressure still bleeds off rapidly,I have checked the injectors & every other possibility,Since I bought the new pump off eBay I don't think warranty is possible so I am thinking of just installing a in line check valve

Good question! I plan to do this mod when the weather warms up in a couple months because I have long crank times during a cold start.

Are you sure pressure is bleeding off through the pump? It could be a leaky injector and a check valve wouldn't do anything to help that.

Absolutely positive no injector leak down verified by pulling the fuel rail/injectors, pressure bleeds to zero in 30 seconds or less,No other leaks,New Airtex pump bleeds off faster than the original pump

This is the route I was going to go about 1.5 yrs ago. I had the valve and everything. I decided to just get a new fuel pump. I enjoyed quick starts for about 1.5 yrs and guess what?

I'm going the inline route the second time around. I bought mine at a Fluid Connector and IIRC it was about $45.

I only put in factory fuel pumps in any vehicle I own for that reason. I do not trust aftermarket fuel pumps. You end up doing the job over and over again even if you have a "lifetime warranty" on the part.

If I was a betting man I'd bet a factory original pump would cure your pressure bleed off problem.

I agree I wish I would have went that route but I do not have another $300 to throw at this problem so thats why I was wanting to put in a external check valve.

I've seen them in the Summit Racing catalog but it was difficult to find since it's not in the index.

When you have a choice, buy American made.

I'm going to keep an eye on this because I'm running into the same issue with the TJ I just brought home and don't want to have a new fuel pump become part of my regular maintenance.

Let us know how it works out.

I can completely understand not wanting to throw more money at it right now, for now you can get brass check valves from McMaster Carr for around $10. You'll have to add a barb pipe fitting to each end to install it in your jeep. Here's the link.

You are welcome. I use McMaster Carr all the time. Their southeast warehouse is in Atlanta so I get ground delivery the next day here in Savannah. I am sure Jacksonville is still in their one day range on ground shipping too.
