Walbro fuel pump
I’m looking at putting a Walbro fuel pump on the truck. It only has one tank on it. My plan is a 190 lph pump. Any advice on the install and what part number did you use?
By fall time, I will be doing work to put me around 350 hp/tq range.
I’ve owned the truck 3.5ish and this is the 4th time I’ll be replacing the “lifetime warranty” pump. This time it left me stranded at a grocery store with my landscaping trailer!! I’m truly tired of this. Replacement warranty pump won’t come in until
this afternoon and I’m supposed to get two days of rain starting tonight. I had 7 more lawns to do!
Rant over…

Which pump are you going with? I've heard that they have some high volume in tank pumps out now that would probably be the way to go. I've got the GSL392BX pumps which are 255 lph. I haven't had one fail me in the 4 years that I have been running it, probably because I bought a couple of spares for just in case. Walbro suggests using a 100 micron pre filter, so I ended up with an Aeromotive 12319. Definitely, DO NOT waste money on a small prefilter. You will be constantly changing them when your engine starts leaning out.

In tank is my plan. I would love to just go with a rail pump if it would pull through the FDM without a problem.. I’m tired of dropping the tank! I was looking at the LMR kit for a mustang:

$10 more and I can do 255, but I didn’t feel like it was fully necessary. Maybe just say screw it and do the 255. Looking on their site, there are 3 types to choose from, all based on sock type/location on bottom pump.

I had a convo with the O Reilly manager and told them I was tired of changing it out so frequent and I lost most of my income for the day, potentially the week with the weather. I said I was going to swap to another fuel pump really soon. She actually said she agreed and was good with me returning the new one in the truck now for a full refund. If i go the Walbro route, I’ll need to go to a junkyard and get another fdm. That will still leave no money out of my pocket essentially.
O Reilly pump is $150
255 Walbro kit is $114. I can’t imagine a JY pump will be more than $30-40.
Anyone have a junk fdm for a front tank they want to part with?!
