So I recently checked the fuel pressure on the truck and I was only getting 49-50 psi…and since the recommended pressure is 60 psi I changed the fuel filter and put a new fuel pump in the tank…checked the fuel pressure again and that changed nothing…the fuel pressure remained at the 49-50ish range… Upon doing some further investigating and following fuel lines I’ve discovered the truck also has an inline external fuel pump mounted between the regular fuel filter and the engine…just out of sight from the filter… This inline pump had apparently went out and was no longer working…I have no idea when it quit just know the pump is out…it’s an AIRTEX E8445 fuel pump that is supposed to push at 65 psi…
Question 1
With this pump being out and inline restrict the fuel pressure from the tank to the engine? Common sense says it could…but at the same time would it really though???
Question 2
Will an inline pump increase the pressure from the pump in the tank or will it basically be limited to the max pressure being pushed to it from the tank? (Does that make sense? lol)
Question 3
I’m going to put a new inline pump back on the truck since the truck is already plumbed for it and it’s done rather nicely. Any suggestions/thoughts/opinions/advice/preference on which brand to go with and what pressure rating would you suggest? I’m not looking to spend $400-500+ bucks on a pump when the spider has the basic upgraded spider with the regular size injectors…
Any suggestions would be greatly appreciated and thank in advance…
