Just about to do the fuel transfer pump relay mod and also relocate to closer to the tank and 1/2" lines and straw, question is PO fitted this Fass pump https://www.dieselautopower.com/fass-direct-replacement-fuel-pump-drp02  is this good enough ? truck is 98.5 24v auto, trans is stock as far as I know,  it has been rebuilt by PO late 2017 although looking at the rest of this guys work  that may not mean much. He had used a canister pre filter and nothing else, luckily It hadn't done diddly miles and I got it, the guy wanted £60 for the original filter housing he had thrown under his bench yeah right, I fitted a Cat filter housing but this ****ant prefilter is still in the line, it's like one of those rubbish precarb plastic things you used to see on gas engines but it is steel, I haved a much bigger Cat one to add into the 1/2" lines , I also have a Cat water seperator filter but can't fit that yet as the bowl is clear so will only use that when I have to buy all fuel

I'm looking at a quad later this year when the truck is in better shape fuel wise but realise the trans is the limit.

I have been down the slippery HP slope at Ray Barton RE and have no desire to go there again all I need is belt and braces so I don't break down miles from home as no one in UK will tow this thing LOL

My thinking is DAP straw, relocate TP to frame near tank and relocate Cat filter/filters, put it on a relay and fit a fuel pressure gauge so I know what I'm dealing with, if it comes in below what's needed pressure wise fit a Cat 9.3L 12v fuel transfer pump which will put at least 70% back to tank....??

that is good for stock or a canbus box only, anything else i would go with a larger pump

going to do the mods, fit a gauge and make the decision after that..... I really don't want to get on that silly power slope as I said been there done that
