Have not seen a problem with plastic unless the fuel goes completely sour. At first I thought it was the ethanol alone but it appears it is more the overall blend than a single component.
Until I saw what the molds for these were costing the plan was to do the small boots as well, those got axed quickly. Not needed unless a baffle breaks loose....oops, wasnt that one of your things? Many of the models used the same in-tank components and is the reason the molds are complicated. I had to make a single outside shape/size mold with various sizes on the inside for the different pump diameters. Had I made 3 molds for these I would never had seen blue sky on this. Its all in the insurance companies hands now....I should have a policy price in the next day or so and that will tell me if we are all stuck with the SOP or if I can afford to cover the policy costs and still follow through as planned
Not necessary to use the little boot covers inside the tank if you connect properly. BTW those boots are the first things to turn to goo. Ernie your rubber sleeves looked great compared to mine....mine were completely dissolved and nothing was left but some black goo all in the pump housing/assembly.
The plastic shield and basket/filter were in good shape on mine and I consider my problem to be the absolute worst scenerio you will encounter. However the plastic fuel supply and return hoses where so brittle that when the rubber sleeves melted that hold the fuel pump it cracked these plastic hoses and they had to be replaced.
Update. One step in the process. TR drainback hoses were used as an experiment for the fuel cross over hoses for the earlier cars. These drain back hoses are made with a thinner liner layer than the fuel hoses but the same Aramid fiber exterior. Non pressure fuel hoses (crossover and fill neck) will be the same appearance but half the wall thickness of the hose photo'ed. Aramid fiber is what Nomex (drivers suits, Fire dept gear) is made of.....that ought to take care of any heat/fire resistant concerns FAR beyond what has been done to date. The same liner material used in this hose is what the fuel components will be molded of IF I can get the blessing of an insurance company, thankfully I have the assistance of a Chat member helping me in that area. If this is able to be followed through to the end it will be due to a great number of folks all pitching in their tallents. If I had made a decision based on my insurance reps numbers, we would all be stuck with the same old OEM parts and I would chalk up a great deal of time to an expensive education and walked away. There is still hope but this is the problem with trying to do this type of thing in such small scale, insurance costs sink many a ship! Twice the rating the Military and USCG feel is needed and still..... To get everything absolutely correct the first time, all must be done in steps. The hose company knows what they are doing and have done this for many thousands of feet of hose, now I have to be convinced everything is as good as it can be before proceeding. At first inspection it is like the coolant hose...way beyond my expectations! Image Unavailable, Please Login
