So I figured I would write up my conversion to and intank fuel pump using a stock fuel tank. I was having issues with my inline pump and decided it would be better to make the switch. At the same time I am converting to a different style sending unit that should play nicer with my after market fuel gauge.

I have been running the holley sniper kit that comes with earls vapor lock fittings and a pump that was supposed to be capable of supplying the required 58 psi for my FiTech. However the pump would just randomly quit on me while driving. Not sure if it was getting hot from the exhaust pipes or what it was. But after 30 minutes are so the car would start and I could drive again.

I have a fairly new stock fuel tank and didn't want to buy a new one. I decide to use the FiTech intank conversion kit.


Also I was having erratic fuel level readings with the stock sender and aftermarket gauge. Tanks inc makes this floatless sending unit.


I am using all Earls Vapor Lock fuel line and fittings for this. And changing my old 5/16 supply line over to a 3/8.

Sorry about that. I have been busy trying to finish up my Doctoral degree. And then we had the freeze here in Texas. I promise will get the pics and write up done.

Fuel pumps are known for poor quality control. The ones that fail seem to do so fairly quickly. You could try your luck with another easy-to-install fuel pump

"Fuel pumps"? As in all fuel pumps are known for poor quality control? Every single type and brand?

I have never had a Walbro pump fail and they are pretty cheap...I am sure the equivalent Walbro would plug right in(a lot of in-tank pumps are the same models...some type of industry standard for inlet/outlet locations and sizes if I had to make a guess).

Trouble is there are many near perfect knockoffs of the Walbro 340 series. Holley doesn't specifically say what brand pump they use. I read on a Holley forum that these basic fuel pumps are the same design whether used in an in-tank setup or in-line. I used to hear that low fuel can cause an in-tank pump to fail early from heat. But Holley says that isn't true.

I have a Bosch fuel pump from a 98 Ford Escort sitting here that looks very similar. Those rarely fail.

That looks exactly like the Bosch fuel pump I put in my wife's 99 Explorer sport.

Of course, a fuel pump that looks the same may not be the same. There's PWM, etc. But many similar fuel pumps last the life of a car. It's common for aftermarket pumps to fail sooner. Sometimes much sooner. The reason for these failures is a matter of debate. It's probably caused by debris in the lines, tank, regulator, or filters.

I've ran the Walbro GS342 (255lph) a few times without issue. Yes, sometimes they do fail, but mine never did. They're like $80 though and should be all a Mustang guy needs assuming gasoline, naturally aspirated. At carb pressure you'd have even more room. Order from Summit and you should be getting the real thing. They're loud though. Some louder than others which nobody can explain either.
