The rubber hoses between the main fuel pump and the tank on my 93 940T are looking a little worrying. I read in the FAQs that the fittings are 1/2", so I bought what was described as a 1/2" fuel injection hose. But then, I opened the back of the caliper to the ID of the hose, pulling out when I encountered slight resistance. When I put the other end of the caliper over an exposed section of pipe, it fit a little too easily. Couldn't wiggle it, but it didn't quite feel like a match.
I come on here and do a search like I should have in the first place, and see that 7/16" or 12mm hose is preferred over 1/2". But here's where it gets interesting. This is a Gates Barricade MPI hose, and the text on the hose describes its ID as 12.5mm instead of the 12.7mm that every other 1/2" hose seems to measure. I have a few questions about this.
Will the missing .2mm make enough of a difference that I can just throw this crap on and be done with it? If the caliper is any indication, it will slide on and not wiggle, but it will slide on maybe a bit too freely. Is that good enough in this situation?
I learned from my search that 30r9 is the standard for these hoses, but this one says it's 30r14t2. 30r14t2 isn't in the one SAE manual I was able to find. Every statistic I can find for 30r14t2 makes it sound like it would be more than good enough for the tank to fuel pump connection, but is there anything about that location that would cause these hoses to fail prematurely?
