Today was the day,.. i,ve been plagued with a no start,. or start up and die situation for a while,.and it,s the classic case of air in the lines etc,.i,d hot wire the fuel pump bleed the fuel filter etc,. etc,.then it,d wind over for quite a while and then mebbe fire, of i,d have to start all over again so the GP's were hot,.
I noticed that it got progressively worse as the fuel level dropped, so that was my clue,.
I dropped the tank and sure enough the pickup line was rotten,.

Here's a pic of the new unit, along with the barbed fittings adapters i,m going to use,.i,m a firm believer in rubber fuel line and good clamps over barbed fittings,.
and it makes it real easy for diconnect next? time.

I,m going to use a racor filter mounted high on the firewall drivers side, so it has a nice gradual downhill slope to the pump,.
I also bought a new fuel pump, the old one was an E3309, and even tho it was working it didn't seem to be moving much fuel,.took forever to fill up a small water bottle,.(10secs) so i bought an E8153 pump, identical in everyway except output,.it takes 3 secs to fill the same small water bottle,.:D and it was cheaper than an ac/delco stock pump,.(e3309)
i,m also looking at putting a check valve right at the pump so it doesn't bleed back from the filter,.and again barbed fittings in and out on the pump and all rubber fuel line from tank to IP,.(stuff is expensive)
I also will add the bigger 3/8ths IP fitting when it gets here, the factory stuff is rather weenie,. it's all 3/8ths till it comes out of the fuel manager, where it,s only 5/16ths to the IP,.

I,m also going to add a relay that powers the lift pump when the glows are on,.later OBD2 trucks have this feature which helps to take up any slack in the fuel supply before the motor fires,.
The stupid speed nuts on the tank straps spun of course,. so i had to take my 4" cutoff wheel and cut the bolts,.haha the tank drops real quick that way,.(oof!) To reinstall the tank i,m using threaded rod and locking nuts and new speed nuts up on the cross member,.
If this doesn't cure the problem,. it just might catch fire,.:mad:...
