What have you done to your square lately??

I had this problem with idling and response in my 88 tbi, tech guy recommended dropping the fuel tank and replacing fuel pump and sending unit....fixed my issue... good luck.

I agree, it is definitely the usual symptoms of a weak fuel pump.

Reminds me of when my fuel tank sock was completely screwed possibly a issue @JamesSam

Replaced the low pressure power steering hose on the 75 then drove it around a bit looks like the high pressure hose is leaking just replaced the old oil soaked low side because I had 3/8" hose already busted the generator out and got it running hadn't run it for 6 months also dragged out the welder to finish up the gooseneck I'll get it done the next few days I'd like to have my main truck back lol

@Ajax19 , and @Redfish ,

I am thinking by now you both have replaced tanks/sending units/fuel pumps on your TBI trucks by now. Could you guys both tell me where you got your tanks from?
I have looked in to getting all new tanks, pumps etc...so I have a general idea of what I would be spending and the work it would require, I would just like your perspective on which ones(where you got your stuff) you chose and what you experienced. Since you both have the TBI sickness like me.
I have read many a thread and watched many a video on dropping and replacing tanks. It is quite an intimidating task(for me) especially with dual tanks...whoof.

Spectrum is the brand of tank I bought. Made in Canadastan, good stuff.

Washed it and swapped the front tag yesterday and they’ve already re-brined the roads for the 18* and possible snow chance Tuesday

@JamesSam i bought my new tank, pump/sending unit and selector valve from Oreilly. All fit great and worked fine for the years prior to selling the truck. (My 1987 R1500, 350 TBI)

I just removed the tank sock and put a filter inline under the truck on the squares I have now are both carb, I sold my tbi truck a few years ago never had any issues with them but now these trucks are getting older the way I see it can't be made at 40-50year old parts going bad I know you'll get her fixed up my dog said whooof up lol

Thanks Paul, good to know.

@JamesSam when I bought The Truck the tanks had already been replaced. The PO told me they re-used the fuel pumps.

Initially I felt that the RH tank must have a weaker pump than the LH tank but as time has passed I can tell no difference. You could have a switching valve issue, I am assuming you have not tried switching tanks to see if the truck runs better on one pump than the other.

I don't think dropping the tank is that bad of a job. Of course I have some jacks and things to help me.

Both of my tanks used to work then the drivers side died on me one day. I would switch periodically to keep things flowing, so I have always had an idea that this tank/pump/selector/sending unit issue would be abrupt and necessary.

I’m glad we Canadians are now referred to Canadastanians, granted that dimwit of a PM we have up here I understand and agree with the reference, just so we are clear some of us aren’t opposed to becoming the 51 st State, S!ft the American fast food culture is overtaken us already.
